Civil Law And Airline Bankruptcy Passenger Compensation Claims In Europe

1. Introduction

Airline bankruptcy creates a difficult civil-law problem because a passenger may have a valid right to reimbursement or compensation, while the airline may simultaneously be insolvent and unable to pay.

In the European legal framework, three different questions must be separated:

Did the passenger acquire a right to compensation or refund?

Who is legally responsible for paying it?

How can the passenger actually recover the money when the airline enters insolvency proceedings?

The principal EU instrument is Regulation (EC) No 261/2004, which provides standardized rights for cancellation, denied boarding and long delays. Article 7 provides fixed compensation of €250, €400 or €600 depending on flight distance, while Article 8 provides reimbursement or rerouting rights. (EUR-Lex)

A major difficulty is that Regulation 261/2004 does not itself create a general insolvency-protection fund for passengers who have purchased flight-only tickets. The European Commission has specifically noted that passengers' prepayments are not generally protected against an air carrier's insolvency under the Air Passenger Rights Regulation. (EUR-Lex)

Therefore, airline bankruptcy passenger claims sit at the intersection of:

EU passenger-rights law;

contract law;

insolvency law;

consumer protection;

the Montreal Convention;

package-travel law;

national civil procedure and insolvency-ranking rules.

2. Meaning of Airline Bankruptcy Passenger Compensation Claim

An airline bankruptcy passenger compensation claim arises where:

A passenger has a legally enforceable claim against an airline for reimbursement, statutory compensation, damages, expenses or other passenger-rights relief, but the airline enters insolvency proceedings before the passenger receives payment.

Typical situations include:

airline cancels flight and subsequently becomes insolvent;

passenger purchases ticket but airline ceases operations;

passenger obtains a €250/€400/€600 Regulation 261 claim before bankruptcy;

passenger has already received a court judgment but airline enters insolvency;

passenger incurs hotel or replacement-flight costs;

passenger holds an unused ticket when insolvency occurs;

passenger claims damages under the Montreal Convention;

airline collapses after a mass cancellation.

The crucial distinction is:

Existence of a claim ≠ actual recovery of money.

3. Principal European Legal Framework

A. Regulation 261/2004

Regulation 261/2004 establishes minimum passenger rights for:

denied boarding;

cancellation;

long delay.

For qualifying cancellations, Article 7 provides:

The regulation also provides reimbursement or rerouting and rights to care. (EUR-Lex)

The regulation is therefore the primary statutory source of passenger compensation, but it does not guarantee that an insolvent airline will have sufficient assets to satisfy the claim.

4. Reimbursement Is Different From Compensation

This distinction is extremely important.

Ticket reimbursement

Where Article 8 applies, the passenger may choose:

reimbursement;

return to the first point of departure; or

rerouting to the final destination.

The regulation specifies reimbursement of the ticket price within seven days in the relevant circumstances. (EUR-Lex)

Fixed compensation

Article 7 compensation is different.

For example:

A passenger buys a €150 ticket.

The airline cancels the flight without sufficient notice and no extraordinary circumstance applies.

Potential claims may include:

€150 ticket reimbursement; and

€250 statutory compensation, if Article 7 applies.

Thus:

Refund claim + statutory compensation claim = potentially separate claims.

5. What Happens When the Airline Becomes Insolvent?

Suppose:

Passenger purchases ticket → airline cancels → passenger obtains a €400 claim → airline enters insolvency.

The passenger may have a valid substantive claim, but enforcement changes.

The passenger generally becomes a creditor in the insolvency proceedings, subject to the applicable national insolvency law.

The practical issues include:

whether the claim arose before insolvency;

whether it is a secured or unsecured claim;

whether the passenger must formally lodge the claim;

applicable filing deadlines;

whether interest and costs are admitted;

whether the claim ranks alongside ordinary unsecured creditors;

whether a statutory guarantee or insurance mechanism applies;

whether the passenger can recover through a credit-card provider or other intermediary;

whether package-travel protection applies.

Historically, the European Commission observed that many passengers affected by airline insolvency had to seek reimbursement as creditors of the failed airline through national insolvency procedures. (EUR-Lex)

6. Airline Insolvency Does Not Automatically Destroy the Passenger's Underlying Right

A central civil-law principle is:

Insolvency affects enforcement and distribution; it does not necessarily erase a pre-existing substantive claim.

For example, if a passenger became entitled to €400 under Regulation 261/2004 before the airline entered insolvency, the claim may remain legally valid.

But the passenger must then deal with insolvency law.

The actual recovery may be:

100%;

partial;

delayed;

or potentially zero,

depending on the insolvent estate and creditor-ranking system.

7. Passenger Claims Can Arise Before or After Insolvency

A. Claim arising before insolvency

Example:

Flight cancelled on 1 June.

€400 compensation becomes due.

Airline enters insolvency on 15 June.

The passenger normally has a pre-insolvency claim that must be handled through the insolvency process.

B. Claim arising after insolvency

The situation can become more complicated if an insolvency administrator or restructuring process continues to operate flights and subsequently breaches passenger obligations.

The applicable national insolvency rules and the precise legal relationship become important.

8. The Airline Remains the Primary Passenger-Rights Debtor

Regulation 261/2004 generally places passenger-rights obligations on the operating air carrier.

This is important in multi-party arrangements involving:

travel agencies;

tour operators;

ticket intermediaries;

code-sharing airlines;

charter companies;

wet-lease operators.

The CJEU has repeatedly treated the operating carrier as responsible for relevant Regulation 261/2004 obligations. For example, in Aegean Airlines, C-163/18, the Court examined the relationship between the airline, passenger and tour organiser. (EUR-Lex)

9. Case Law

Case 1 — Wallentin-Hermann v Alitalia, C-549/07

Court: CJEU
Date: 22 December 2008

Principle

The Court held that technical problems arising in the normal activity of an airline generally constitute circumstances inherent in normal air-carrier activity.

Importantly, compliance with minimum maintenance requirements does not automatically establish that the airline took all reasonable measures.

(EUR-Lex)

Relevance to bankruptcy

If an airline argues that repeated technical problems justified cancellation and therefore eliminated compensation, bankruptcy does not itself determine whether Article 7 compensation was originally owed.

The substantive compensation question must first be determined.

10. Case 2 — Sturgeon and Others, C-402/07 and C-432/07

Court: CJEU
Date: 19 November 2009

Principle

The CJEU established that passengers suffering sufficiently long delays can, under the conditions identified by the Court, obtain the same standardized compensation as passengers whose flights are cancelled.

This case is fundamental to the development of the EU compensation regime.

Bankruptcy relevance

If the delay creates an Article 7 compensation entitlement, the passenger may have a monetary claim even though the airline subsequently becomes insolvent.

The important legal sequence is:

Delay → qualifying entitlement → monetary claim → insolvency enforcement.

11. Case 3 — Nelson and Others, C-581/10 and C-629/10

Court: CJEU
Date: 23 October 2012

Principle

The CJEU confirmed the compatibility of standardized compensation under Regulation 261/2004 with the Montreal Convention.

The Court emphasized that Regulation 261/2004 provides standardized and immediate compensation, while the Montreal Convention addresses individual damages under different conditions. (EUR-Lex)

Bankruptcy relevance

This distinction is important because a passenger may have:

a Regulation 261 statutory claim; and

a separate claim for individual damage under applicable international/national law.

The two should not automatically be treated as the same claim.

12. Case 4 — Sousa Rodríguez and Others, C-83/10

Court: CJEU
Date: 13 October 2011

Principle

The Court explained the relationship between Regulation 261/2004 and additional compensation.

Article 12 permits further compensation under applicable law, including damages arising from breach of the contract of carriage. (EUR-Lex)

Bankruptcy relevance

An insolvent passenger claim may therefore contain different components:

The insolvency administrator may need to distinguish these components.

13. Case 5 — Aegean Airlines, C-163/18

Court: CJEU
Date: 10 July 2019

This is particularly important for insolvency analysis.

The Court considered a situation involving package travel and an insolvent tour organiser.

The Court held that where a passenger has a right under the package-travel regime to hold the organiser liable for reimbursement of the air-ticket price, the passenger cannot additionally claim that ticket reimbursement from the airline under Regulation 261/2004 merely because the organiser is financially incapable of paying. (EUR-Lex)

Importance

This illustrates the principle:

The existence of insolvency does not automatically transfer a reimbursement obligation from one legally responsible party to another.

That distinction is crucial in airline insolvency litigation.

14. Case 6 — Rechberger and Others, C-140/97

Court: CJEU
Date: 15 June 1999

This case concerned package-travel insolvency protection rather than direct airline insolvency.

Principle

The Court held that the former Package Travel Directive required effective protection ensuring reimbursement of money paid by consumers when a travel organiser became insolvent.

The guarantee had to be effective regardless of the cause of the insolvency. (EUR-Lex)

Importance for airline bankruptcy

It demonstrates an important European-law distinction:

Package travel → statutory insolvency protection

versus

Flight-only purchase → historically weaker insolvency protection.

This difference can materially affect the passenger's recovery prospects.

15. Case 7 — Dillenkofer and Others, C-178/94 and Others

Court: CJEU
Date: 8 October 1996

Principle

The Court dealt with Member-State responsibility for inadequate implementation of package-travel insolvency protection.

The case established important principles concerning effective consumer protection and state liability where EU obligations have not been properly implemented.

Relevance

If a passenger's protection is dependent upon national implementation of an EU insolvency guarantee, inadequate implementation may potentially raise a separate state-liability issue, although such claims require satisfaction of the stringent conditions developed in EU state-liability jurisprudence.

16. Case 8 — Finnair Oyj v Keskinäinen Vakuutusyhtiö Fennia, C-22/11

Court: CJEU

This case concerned the relationship between passenger claims and the carrier's contractual obligations in air transport.

Relevance to bankruptcy

It illustrates that passenger rights must be analysed according to the specific legal relationship and applicable EU/international aviation framework rather than simply treating every monetary passenger claim as an ordinary contractual debt.

For insolvency purposes, identifying the correct legal source of the claim is therefore essential.

17. Case 9 — Flightright and Others, C-274/16, C-447/16 and C-448/16

Court: CJEU
Date: 7 March 2018

Principle

The CJEU addressed jurisdiction and passenger compensation claims involving operating carriers and contractual arrangements.

The Court recognized the contractual character of relevant passenger claims even in situations involving parties other than the passenger's direct contractual counterparty. (EUR-Lex)

Insolvency relevance

This becomes important where:

ticket seller;

travel agency;

tour operator; and

operating airline

are different entities.

A passenger should first identify which entity legally owes which part of the claim before lodging an insolvency claim.

18. Case 10 — Delfly, C-356/19

Court: CJEU
Date: 3 September 2020

Principle

The Court held that eligible passengers or their legal successors may demand Regulation 261 compensation in the national currency of their place of residence, subject to applicable national rules concerning conversion.

(curia)

Bankruptcy relevance

The case demonstrates that passenger compensation claims retain their EU-law character even where the claimant resides in a non-euro Member State.

In insolvency proceedings, the amount may therefore require:

currency conversion;

determination of the applicable exchange rate;

proof of the claim amount.

19. Case 11 — Verein für Konsumenteninformation v KLM, C-45/24

Court: CJEU
Date: 15 January 2026

This is a recent passenger-rights decision.

The Court interpreted Article 8(1)(a) concerning reimbursement following cancellation.

It held that the ticket price for reimbursement can include an intermediary's commission forming part of the amount paid by the passenger, even where the airline did not know the exact amount of that commission. (Curia)

Bankruptcy relevance

Where an airline is insolvent, determining the correct amount of the passenger's reimbursement claim becomes important.

The claim may therefore not always equal merely the amount that the airline itself received.

20. Recent Case — European Air Charter, T-656/24

Court: EU General Court
Date: 4 March 2026

The Court addressed the causal relationship between an earlier extraordinary circumstance and a later flight delay.

It held that an airline cannot automatically rely on an extraordinary circumstance affecting an earlier flight where the later delay resulted from an autonomous airline decision that was the determining cause of the subsequent delay. (curia)

Relevance

Although this is not an insolvency case, it demonstrates why the passenger's substantive compensation claim must be established independently before calculating what becomes an insolvency debt.

21. The Major Legal Problem: No General Flight-Only Insolvency Guarantee

This is one of the most important points.

EU passenger-rights law historically provides strong protection concerning:

cancellation;

delay;

denied boarding;

reimbursement;

care.

But Regulation 261/2004 does not itself establish a general fund guaranteeing repayment of prepaid flight-only tickets if the airline becomes insolvent.

The European Commission has expressly identified this distinction between air passenger protection and package-travel insolvency protection. (EUR-Lex)

Therefore:

Passenger-rights protection is not necessarily the same thing as insolvency protection.

22. Flight-Only Passenger vs Package Traveller

23. Civil-Law Character of the Claim

An airline bankruptcy compensation claim can have several legal characters.

1. Statutory claim

Example:

€400 under Regulation 261/2004.

2. Contractual claim

Example:

Refund for a ticket that was not used.

3. Tort/delict claim

Example:

Additional damage caused by wrongful conduct, where national law permits recovery.

4. International-carriage damages

Potentially under the Montreal Convention.

5. Consumer claim

Where consumer-protection legislation applies.

6. Insolvency claim

Once the airline enters formal insolvency proceedings, the passenger becomes a creditor asserting the underlying claim through the insolvency process.

24. Passenger Compensation vs Ticket Refund

These should be separately calculated.

Example

Passenger pays:

€500 ticket

Airline cancels the flight without applicable exemption.

Potential claim:

€500 refund;

€400 Article 7 compensation;

reasonable care expenses, where recoverable;

potentially additional damages under another legal regime.

Potential total:

€900 + legally recoverable additional losses.

If the airline becomes insolvent, however, the passenger does not necessarily recover €900 in full.

The amount admitted and ultimately distributed depends on the insolvency proceedings.

25. Extraordinary Circumstances and Bankruptcy

Bankruptcy itself does not automatically determine whether Regulation 261 compensation was owed.

The legal test under Article 5(3) concerns extraordinary circumstances that could not have been avoided even if all reasonable measures had been taken.

The CJEU has repeatedly distinguished circumstances inherent in normal airline operations from genuinely external events.

For example:

Wallentin-Hermann — technical problems ordinarily inherent in airline activity;

van der Lans, C-257/14 — unexpected technical failure does not automatically constitute extraordinary circumstances;

Finnair, C-832/18 — premature component failure does not automatically qualify;

European Air Charter, T-656/24 — causal analysis of later airline decisions remains relevant.

Thus:

Financial distress ≠ automatic exemption from passenger compensation.

26. Airline Bankruptcy and Article 13

Article 13 of Regulation 261/2004 is also important.

It preserves the operating carrier's right to seek reimbursement from third parties responsible for causing its obligations, under applicable law.

The regulation therefore does not prevent:

airline → maintenance company;

airline → airport;

airline → tour operator;

airline → supplier

recourse actions.

(EUR-Lex)

But when the airline itself is insolvent, the passenger normally cannot simply bypass the insolvency process and convert the airline's third-party recourse rights into the passenger's own direct claim.

27. Insolvency Ranking

Once an airline enters insolvency, the passenger's substantive claim must be classified under the relevant national insolvency law.

A simplified hierarchy may involve:

secured creditors;

insolvency administration expenses;

preferential creditors;

certain employee/public claims;

ordinary unsecured creditors;

subordinated creditors.

The precise hierarchy differs between European jurisdictions.

A passenger holding a €600 Regulation 261 claim therefore should not assume that the €600 will be paid merely because the claim is legally valid.

28. Date on Which the Claim Arises

A particularly important civil-law question is:

When did the passenger's claim legally arise?

Possible relevant dates include:

date of cancellation;

date of delay;

date on which reimbursement became due;

date of court judgment;

date of insolvency opening.

This can affect:

creditor classification;

limitation;

insolvency registration;

set-off;

interest;

procedural deadlines.

29. Limitation and Insolvency Deadlines

Two different periods may need to be considered:

A. Limitation period

Determined by the applicable legal regime and national law.

B. Insolvency claim-registration deadline

A separate procedural deadline may apply after formal insolvency proceedings begin.

Missing the insolvency registration deadline can create serious procedural consequences even if the underlying passenger claim is otherwise valid.

30. Credit Card and Payment Intermediaries

A passenger may sometimes have an alternative recovery route through:

credit-card chargeback;

card-scheme protection;

payment-service rules;

travel insurance;

ticket protection;

bank guarantees.

These are not automatic substitutes for Regulation 261 compensation.

They depend upon:

payment method;

national law;

card agreement;

insurance policy;

applicable consumer rules.

31. Travel Insurance

Travel insurance can become particularly significant in airline insolvency.

Possible coverage may include:

airline failure;

unused tickets;

additional accommodation;

replacement flights;

repatriation.

However, insurance generally operates according to its own contractual conditions.

The passenger must therefore distinguish:

statutory passenger claim

from

insurance claim.

32. Package Travel Provides a Different Protection Structure

Package travel is particularly important because EU package-travel legislation contains specific insolvency-protection requirements.

The CJEU's jurisprudence under the former Package Travel Directive emphasized an effective guarantee of reimbursement when the organiser becomes insolvent. Rechberger is the leading authority. (EUR-Lex)

This is fundamentally different from assuming that every airline ticket automatically has an equivalent insolvency guarantee.

33. Montreal Convention and Airline Bankruptcy

The Montreal Convention may provide an additional legal basis for individual damages arising from international carriage.

But Regulation 261/2004 and the Montreal Convention perform different functions.

The CJEU explained in Wallentin-Hermann that the Montreal Convention is not decisive for interpreting the “extraordinary circumstances” exemption in Regulation 261/2004. (EUR-Lex)

Similarly, Nelson confirmed that Regulation 261 compensation operates alongside, rather than simply replacing, individual damages mechanisms under the Montreal Convention. (EUR-Lex)

34. Contractual Liability

Under ordinary civil-law principles, the passenger's ticket creates a contract of carriage.

Possible contractual breaches include:

failure to transport;

cancellation;

failure to refund;

failure to provide agreed services;

breach of applicable passenger-rights obligations.

The contractual claim then becomes subject to insolvency law when the carrier fails financially.

35. Tort/Delict Liability

A separate tort/delict claim might arise where the passenger suffers legally recognized damage beyond the standardized compensation regime.

The claimant normally has to establish:

Duty → breach → causation → damage → legally recognized remedy.

Bankruptcy does not necessarily eliminate the substantive tort claim, but recovery will depend on the insolvency process unless another liable party can be pursued directly.

36. Multiple Responsible Parties

Airline insolvency litigation may involve several entities:

Passenger

↓

Airline

↓

Tour operator / travel agency

↓

Airport

↓

Maintenance organization

↓

Manufacturer

The passenger should not automatically assume that every party is jointly liable.

Liability depends on:

contractual relationship;

statutory responsibility;

causation;

applicable EU law;

national civil law;

insolvency law.

37. Evidence Required by Passengers

A passenger seeking compensation should preserve:

ticket;

booking confirmation;

boarding pass;

cancellation notice;

delay records;

airline correspondence;

compensation application;

refund request;

airline's refusal;

receipts;

replacement-ticket invoices;

hotel bills;

food receipts;

court judgment;

insolvency administrator correspondence;

creditor-registration confirmation.

For large insolvency claims, proof of the precise amount is especially important.

38. Passenger Claim Calculation

A useful calculation framework is:

Total potential claim

Ticket refund

Regulation 261/2004 compensation

Recoverable care expenses

Further legally recoverable damages

−

Amounts already refunded/paid

=

Claim against airline

The resulting claim must then be submitted and treated according to the applicable insolvency law.

39. Example

Assume:

ticket price = €300;

flight cancelled;

passenger entitled to €400 compensation;

passenger spends €180 on necessary accommodation/food;

airline enters insolvency.

Potential claim:

€300 + €400 + €180 = €880

But €880 is the potential legal claim, not necessarily the amount ultimately recovered.

If the passenger is an unsecured creditor and the insolvency estate permits only partial distributions, recovery may be substantially lower.

40. Important Distinction: Compensation vs Insolvency Distribution

This can be expressed as:

Substantive entitlement determines how much is owed.
Insolvency law determines how and to what extent the debt can be recovered.

Therefore:

Regulation 261 entitlement ≠ guaranteed cash payment.

This is perhaps the most important principle for examination purposes.

41. Role of National Civil Law

European airline passenger law is substantially harmonized, but insolvency remains heavily influenced by national procedural and insolvency systems.

National law may determine:

creditor registration;

proof requirements;

ranking;

interest;

limitation;

insolvency administrator powers;

set-off;

distribution;

court jurisdiction;

enforcement.

Thus, “European airline bankruptcy liability” is really a combination of:

EU passenger law + international aviation law + national contract law + national insolvency law.

42. Jurisdiction

Passenger claims can involve questions concerning:

place of departure;

place of arrival;

airline's domicile;

consumer jurisdiction;

insolvency court;

applicable law.

In Ryanair v Niki/related jurisdiction jurisprudence, and especially the CJEU's jurisdiction cases concerning Regulation 261/2004, the Court has recognized important links to the contractual place of departure and arrival. For example, Rehder v Air Baltic, C-204/08 established that claims connected with passenger air transport may generally be brought at the place of departure or arrival under the relevant jurisdiction rules. (EUR-Lex)

Insolvency proceedings can complicate this because the insolvency court may have separate jurisdictional powers.

43. Class/Collective Passenger Claims

When thousands of passengers are affected by airline bankruptcy, collective mechanisms become practically important.

Examples include:

consumer associations;

assignment of claims;

collective litigation;

representative actions;

claims aggregation;

insolvency committees.

However, the availability and procedural structure of collective actions depends upon the relevant national and EU procedural framework.

44. COVID-19 and Airline Insolvency

The pandemic exposed a major weakness in airline insolvency protection.

Airlines experienced:

mass cancellations;

enormous refund liabilities;

liquidity shortages;

government-supported restructuring;

insolvency proceedings.

The underlying legal principle remained:

Cancellation → passenger rights arise according to applicable law.

Financial difficulty alone does not automatically erase those passenger rights.

45. Regulatory Breach vs Civil Liability

A regulator may find that an airline violated passenger-rights legislation.

That does not always mean that every individual claimant automatically receives every category of damages.

Civil litigation still requires analysis of:

legal basis;

standing;

causation;

damage;

limitation;

applicable remedy.

Therefore:

Administrative enforcement and individual civil recovery are related but distinct.

46. Practical Legal Test

For an airline bankruptcy passenger claim, apply this sequence:

Step 1 — Identify the flight

Was it covered by Regulation 261/2004?

Step 2 — Identify the event

Was there:

cancellation;

long delay;

denied boarding;

failure to reroute?

Step 3 — Identify the legal right

Was the passenger entitled to:

reimbursement;

rerouting;

care;

€250/€400/€600 compensation;

further damages?

Step 4 — Determine the debtor

Who legally owes the money?

operating carrier?

tour organiser?

travel intermediary?

insurer?

Step 5 — Determine when the claim arose

Before or after insolvency?

Step 6 — Lodge the claim

Follow the relevant insolvency procedure.

Step 7 — Determine ranking

Is the passenger:

secured;

preferential;

ordinary unsecured;

subordinated?

Step 8 — Examine alternative recovery

Consider:

insurer;

credit-card provider;

package-travel guarantee;

other legally responsible entity.

47. Six Most Important Cases to Memorize

48. Short Exam Answer

Airline bankruptcy passenger compensation claims in Europe are governed by a combination of Regulation 261/2004, the Montreal Convention, contract law, consumer law and national insolvency law. Regulation 261/2004 gives qualifying passengers rights to reimbursement, rerouting, care and standardized compensation of €250, €400 or €600. However, the Regulation does not itself provide a general insolvency guarantee for prepaid flight-only tickets. (EUR-Lex)

When an airline becomes insolvent, a passenger's existing compensation or refund entitlement generally becomes an insolvency claim whose practical recovery depends on national insolvency procedures and creditor ranking. The CJEU cases of Sturgeon, Wallentin-Hermann, Nelson, Sousa Rodríguez and Aegean Airlines establish important principles concerning the existence and nature of passenger claims, while Rechberger demonstrates the stronger insolvency-protection model applicable to package travel.

49. Final Legal Formula

The topic can be remembered as:

Passenger contract

↓

Cancellation / delay / denied boarding

↓

Regulation 261 entitlement

↓

Refund + standardized compensation + care

↓

Airline becomes insolvent

↓

Claim becomes insolvency debt

↓

Registration + verification + ranking

↓

Distribution from insolvency estate

↓

Alternative recovery where legally available

Core principle

European passenger law can establish the airline's obligation, but insolvency law determines the practical route and extent of recovery.

The most important distinction is therefore:

“Right to compensation” is not the same as “guaranteed recovery of compensation.” (EUR-Lex)
