Aviation Alliances and Competition Approval

1. Introduction

An aviation alliance is a form of cooperation between two or more airlines through which they coordinate some aspects of their operations without necessarily merging into a single corporate entity. Alliances may range from relatively limited code-sharing and interlining to extensive joint ventures involving coordinated pricing, capacity, scheduling, marketing and revenue sharing.

Competition authorities therefore face a central question:

Does the alliance create efficiencies and expanded connectivity that benefit consumers, or does it substantially eliminate competition between airlines that would otherwise compete independently?

The issue is particularly significant in international aviation because market access, airport slots, bilateral air-service agreements and hub concentration can make competition highly route-specific.

In the United States, international airline alliances may receive antitrust immunity (ATI) from the Department of Transportation under 49 U.S.C. §§ 41308–41309. In the EU, alliance arrangements are principally examined under Article 101 TFEU, while transactions involving acquisition of control may additionally fall under EU merger control. In India, combinations involving airlines can be reviewed by the Competition Commission of India (CCI) under the Competition Act, 2002, while operational matters remain subject to aviation regulation.

2. Types of Aviation Alliances

A. Code-sharing

One airline sells seats under its own airline code on a flight operated by another airline.

Example:

• Airline A operates Delhi–London.
• Airline B markets the same flight under its own flight number.

Competition concerns arise where the airlines are actual or potential competitors on the same route.

B. Interlining

Airlines coordinate connecting itineraries and ticketing but retain relatively independent operations.

C. Frequent-flyer cooperation

Airlines permit passengers to earn or redeem loyalty points across the partner network.

This can increase network attractiveness but can also strengthen barriers to entry where loyalty programmes become important competitive assets.

D. Joint ventures

The most competition-sensitive form involves extensive coordination over:

• prices;
• schedules;
• capacity;
• revenue;
• inventory;
• sales;
• marketing; and
• network planning.

A revenue-sharing joint venture may effectively cause the participating airlines to behave as a single economic entity for particular routes, even though they remain separate corporations.

E. Global alliances

The major global alliance structures include:

• Star Alliance;
• oneworld; and
• SkyTeam.

The U.S. DOT has historically granted ATI to numerous international alliance arrangements, including alliances involving these networks.

3. Why Competition Approval Is Necessary

An alliance can produce substantial efficiencies.

Potential benefits

1. Expanded network coverage
2. Better connecting schedules
3. Reduced duplication
4. More efficient aircraft utilisation
5. Joint marketing
6. Improved passenger connectivity
7. Frequent-flyer reciprocity
8. Lower transaction costs
9. Greater international market access
10. Potentially improved service frequency

However, extensive cooperation can also transform competitors into coordinated partners.

The principal danger is that:

An alliance may produce merger-like competitive effects without formally constituting a merger.

This is why regulators examine the substance of the cooperation rather than merely its legal form.

4. Principal Competition Concerns

A. Price coordination

Where alliance members coordinate fares, there may be little or no independent price competition between them.

This is particularly significant where the airlines are major competitors on a city-pair route.

B. Capacity coordination

Airlines may jointly determine:

• frequency;
• aircraft size;
• seat inventory;
• flight timings; and
• capacity allocation.

If competing airlines jointly reduce capacity, the resulting effect may resemble coordinated supply restriction.

C. Schedule coordination

Schedule coordination can produce efficiencies for connecting passengers.

But on overlapping routes, it may also remove independent competitive strategies.

D. Airport-slot concentration

Airport slots are often scarce.

An alliance controlling substantial numbers of slots at:

• Heathrow;
• Frankfurt;
• Amsterdam;
• Paris;
• New York;
• Tokyo; or
• other constrained airports

may make market entry or expansion difficult.

The European Commission specifically identified airport-slot scarcity as an important factor in its examination of the BA/AA/Iberia transatlantic joint venture.

E. Frequent-flyer programmes

A large alliance may have significant advantages in:

• corporate contracts;
• loyalty programmes;
• accumulated miles;
• passenger switching costs.

A new entrant may therefore find it difficult to compete even if it can obtain aircraft and airport slots.

F. Access to connecting traffic

Hub airlines depend heavily on connecting passengers.

An alliance can potentially control or redirect connecting traffic in ways that make competing airlines less viable.

This was expressly considered in the EU's BA/AA/Iberia investigation.

G. Market foreclosure

Alliance members may possess significant control over:

• airport facilities;
• reservation systems;
• connecting networks;
• corporate travel contracts;
• loyalty programmes; and
• distribution channels.

The resulting concern is foreclosure of rival airlines.

5. Competition Approval Framework

United States

The U.S. system is distinctive.

The Department of Transportation has authority to approve international airline agreements and, where justified, grant antitrust immunity.

The DOT's analysis has historically considered:

• public interest;
• international transportation;
• consumer benefits;
• competition between global alliances;
• network integration;
• market access; and
• competitive overlap.

The DOJ has also examined the competitive consequences of airline immunity, particularly the possibility that immunity could reduce the number of genuinely independent competitors.

Importantly, ATI does not mean that every form of airline conduct becomes automatically immune from every competition law. The scope of the relevant authorization matters.

6. European Union

The principal provision is:

Article 101 TFEU

It addresses agreements and concerted practices that have as their object or effect the prevention, restriction or distortion of competition.

An airline alliance can therefore raise Article 101 issues where it involves:

• price coordination;
• capacity coordination;
• market allocation;
• scheduling coordination; or
• other commercially significant cooperation.

However, Article 101(3) permits restrictive arrangements where the statutory conditions concerning efficiencies, consumer benefit, necessity and preservation of competition are satisfied.

The European Commission has therefore frequently used commitments and remedies in airline alliance cases rather than treating every alliance as automatically unlawful.

7. India

Under the Competition Act, 2002, airline combinations can be examined where they satisfy the statutory combination criteria.

The CCI may consider:

• relevant geographic markets;
• relevant product/service markets;
• market shares;
• closeness of competition;
• airport access;
• route overlaps;
• entry barriers;
• network effects;
• consumer benefits; and
• potential adverse effects on competition.

India's aviation sector also involves coordination with sector-specific aviation regulation.

The CCI's examination of the Jet Airways–Etihad transaction is particularly important because the parties combined investment, governance and commercial cooperation arrangements. The CCI considered international passenger markets using an origin-and-destination approach.

8. Important Case Laws and Regulatory Decisions

1. Lufthansa–United Airlines–SAS Alliance

European Commission, Cases COMP/D-2/36.201, 36.076 and 36.078

This was one of the foundational European examinations of major airline alliance cooperation.

The Commission examined coordination arrangements involving Lufthansa, United Airlines and SAS under the then EC Treaty competition provisions.

Significance

The case demonstrates that:

• airline alliances can constitute competition-law agreements;
• cooperation between major network carriers requires substantive scrutiny;
• international route overlaps are particularly important; and
• regulatory approval cannot be assumed merely because the arrangement is described as an alliance.

Principle

The substance and competitive effects of airline cooperation matter more than its contractual label.

2. KLM–Northwest Joint Venture

European Commission, Case COMP/36/111

KLM and Northwest operated extensive cooperation on transatlantic routes, including coordination involving:

• scheduling;
• marketing;
• sales; and
• pricing.

The arrangement benefited from U.S. antitrust immunity, while the European Commission also examined its compatibility with European competition law. The Commission ultimately closed the relevant proceeding without imposing remedies.

Significance

The case illustrates the interaction between:

• U.S. ATI;
• European competition law;
• transatlantic aviation agreements; and
• efficiency-producing network cooperation.

Principle

Antitrust immunity in one jurisdiction does not eliminate the need to consider competition-law consequences in another jurisdiction.

3. SkyTeam Alliance

European Commission, Case COMP/37.984

The Commission investigated cooperation among members of the SkyTeam alliance.

The participating airlines included carriers such as:

• Air France;
• Delta;
• Alitalia;
• KLM;
• Northwest;
• Korean Air;
• Aeromexico; and
• Czech Airlines.

The Commission received commitments concerning the effects of the cooperation under Article 81 EC, the predecessor to Article 101 TFEU.

Significance

The case illustrates the importance of:

• overlapping routes;
• coordinated services;
• network effects;
• consumer access; and
• commitments designed to preserve competition.

Principle

Large alliance networks can require behavioural commitments where cooperation threatens competition on particular routes.

4. British Airways–American Airlines–Iberia

European Commission, Case COMP/39.596

This is one of the leading modern airline-alliance competition cases.

BA, American Airlines and Iberia proposed a revenue-sharing joint venture covering their transatlantic passenger operations.

The cooperation included:

• pricing coordination;
• capacity coordination;
• schedule coordination; and
• revenue sharing.

The Commission identified competition concerns on several routes, including:

• London–Dallas;
• London–Boston;
• London–Miami;
• London–Chicago;
• London–New York; and
• Madrid–Miami. 

The Commission was concerned that the alliance could eliminate competition between the participating airlines on particular routes and that competitors might be unable to replicate the alliance's network advantages.

Significance

This case demonstrates that regulators examine route-by-route competitive effects, rather than simply assessing the overall size of an alliance.

Principle

A large alliance can be acceptable overall while requiring remedies on individual routes where competition would otherwise disappear.

5. Air Canada–United–Lufthansa A++ Joint Venture

European Commission, Case COMP/39.595

Air Canada, United Airlines, Continental Airlines and Lufthansa developed a transatlantic revenue-sharing joint venture.

The arrangement involved:

• pricing;
• capacity;
• scheduling;
• marketing; and
• revenue sharing.

The Commission initially considered that the arrangement was likely to raise concerns under Article 101 TFEU, particularly where the parties were actual competitors.

The parties subsequently offered commitments, which the Commission made legally binding under Article 9 of Regulation 1/2003.

Significance

This case is especially important because it shows the distinction between:

ordinary alliance cooperation → extensive joint venture → potential elimination of independent competition.

Principle

Revenue-sharing joint ventures receive intensive scrutiny because they can align the economic interests of formerly competing airlines.

6. Air France–KLM–Alitalia–Delta Transatlantic Joint Venture

European Commission, Case concerning the Transatlantic Joint Venture

The Commission examined the profit/loss-sharing joint venture involving:

• Air France;
• KLM;
• Alitalia; and
• Delta.

The arrangement covered passenger services between Europe and North America.

In 2015, the Commission made commitments offered by the parties legally binding under Article 9 of Regulation 1/2003.

Significance

The case demonstrates the importance of:

• transatlantic route overlaps;
• joint revenue arrangements;
• market concentration;
• entry conditions; and
• commitments designed to preserve competitive alternatives.

Principle

Where alliance partners jointly share profits and losses, regulators may treat their incentives as substantially integrated for competitive-effects analysis.

7. Jet Airways–Etihad

CCI, Combination Case No. C-2013/05/122

This is particularly important for Indian competition law.

Etihad proposed to acquire a 24% stake in Jet Airways while the parties entered into:

• an Investment Agreement;
• Shareholders' Agreement; and
• Commercial Cooperation Agreement.

The CCI treated the arrangements collectively because they had the common objective of enhancing the airlines' businesses through joint initiatives.

The CCI examined international passenger markets and used an origin-and-destination approach in assessing relevant markets.

Significance

The case demonstrates that:

Competition authorities may examine interconnected investment, governance and commercial cooperation agreements together rather than artificially separating them.

8. Air India–Vistara–Singapore Airlines

CCI Combination Case — Air India, Vistara, Tata Sons and Singapore Airlines

The CCI reviewed the transaction involving:

• Air India;
• Vistara;
• Tata Sons; and
• Singapore Airlines.

The CCI's public case record categorizes the transaction as a combination approved with modifications.

Significance

The matter demonstrates the contemporary Indian approach to airline consolidation, where the authority can approve a transaction subject to modifications intended to address identified competition concerns.

Principle

Airline consolidation can be permitted while competition concerns are addressed through structural or behavioural modifications.

9. U.S. Department of Transportation – American/British Airways

The U.S. ATI proceedings involving American Airlines and British Airways illustrate the U.S. approach to international airline alliances.

The DOT historically considered whether immunity would produce sufficient public benefits and whether competitive conditions, including international market access and inter-alliance competition, justified immunity.

The historical DOT record also shows that an earlier American–British Airways proceeding was terminated, while later proceedings involved tentative approval subject to conditions.

Principle

ATI is regulatory approval based upon statutory public-interest considerations, not an automatic entitlement of alliance partners.

10. Competition Tests Applied to Aviation Alliances

A regulator will generally examine the following questions.

Step 1 — Identify the relevant market

Possible market definitions include:

• city-pair/O&D markets;
• airport-pair markets;
• connecting markets;
• passenger segments;
• premium/non-premium passengers;
• cargo markets.

The O&D approach is particularly important because passengers generally regard alternative itineraries between the same origin and destination as potential substitutes.

Step 2 — Identify overlapping routes

The authority asks:

Were the alliance members actually competing against each other before cooperation?

If the answer is yes, the alliance requires much closer scrutiny.

Step 3 — Examine market shares

Relevant indicators may include:

• passenger shares;
• seat capacity;
• frequencies;
• airport slots;
• connecting traffic;
• corporate contracts.

Step 4 — Examine entry barriers

Authorities consider:

• airport congestion;
• slot scarcity;
• bilateral air-service restrictions;
• aircraft availability;
• airport infrastructure;
• regulatory restrictions;
• loyalty programmes; and
• network effects.

Step 5 — Examine efficiencies

The airlines may demonstrate:

• increased frequencies;
• improved connections;
• lower costs;
• new routes;
• better aircraft utilisation;
• improved consumer choice.

Step 6 — Examine whether efficiencies require the restraint

This is crucial.

The question is not merely:

"Does the alliance create benefits?"

It is:

"Are the restrictive aspects of the alliance reasonably necessary to obtain those benefits?"

Step 7 — Assess consumer benefit

Potential benefits include:

• lower fares;
• more destinations;
• improved schedules;
• increased frequencies;
• better connections;
• enhanced service quality.

11. Typical Competition Remedies

Regulators may impose remedies rather than prohibit an alliance completely.

A. Slot remedies

Alliance members may be required to make slots available to competitors.

B. Frequency commitments

The parties may be required to maintain particular service levels.

C. Access to connecting traffic

Competitors may receive improved access to connecting passengers.

D. Interline commitments

Alliance participants may be required to enter interline arrangements with competing carriers.

E. Fare commitments

In appropriate cases, mechanisms may be introduced to prevent certain competitive harms.

F. Withdrawal from particular routes

Parties may be required to modify cooperation on specific city-pairs.

G. Monitoring trustees

A regulator may require independent monitoring of compliance.

12. Alliance Versus Merger

The important point is that an alliance can produce merger-like effects even without a legal merger, particularly where it involves revenue sharing and comprehensive coordination.

14. Key Legal Principles from the Case Law

Principle 1 — Form does not control

Calling an arrangement an "alliance" does not protect it from competition law.

Principle 2 — Route-level analysis is critical

An alliance may produce little concern on one route and substantial concern on another.

Principle 3 — Revenue sharing increases scrutiny

Profit/loss sharing can substantially remove incentives for alliance members to compete independently.

Principle 4 — Airport slots matter

Even a theoretically contestable market may be difficult to enter when airport capacity is constrained.

Principle 5 — Network effects matter

The combined alliance network can become substantially more valuable than the sum of individual routes.

Principle 6 — Consumer benefits must be substantiated

Claims concerning better connectivity, lower fares or expanded services must be assessed against the actual competitive restrictions.

Principle 7 — Remedies can preserve competition

Slot releases, access commitments and route-specific modifications can sometimes address competitive concerns without eliminating the alliance.

Principle 8 — International coordination requires multi-jurisdictional analysis

An alliance may be reviewed by several authorities because aviation markets cross national borders. U.S. ATI, EU competition law and Indian combination law operate through different legal mechanisms.

15. Conclusion

Aviation alliances occupy an unusual position in competition law because they can simultaneously be pro-competitive and competition-reducing.

They can generate substantial benefits through:

• network expansion;
• coordinated connections;
• increased international access;
• economies of operation; and
• improved passenger convenience.

At the same time, extensive cooperation involving pricing, capacity, schedules and revenue sharing can eliminate competition between airlines that previously competed independently. The BA–American–Iberia, A++ and Air France–KLM–Alitalia–Delta matters demonstrate the importance of examining precisely where such coordination affects competition.

The central competition-law principle can therefore be stated as:

An aviation alliance should be assessed according to its actual economic integration, the markets and routes affected, the competitive relationship between the members, the barriers faced by rivals, and the demonstrable consumer benefits produced by the cooperation.
