IATA and ELFAA ruling: CJEU validates Regulation (EC) 261/2004

The IATA and ELFAA v Department for Transport ruling (CJEU, Grand Chamber, 10 January 2006, C-344/04) is the foundational ruling of the entire EC 261 edifice. Without it, the Regulation might never have survived its first attacks.

The context: airlines attack the Regulation

From the adoption of Regulation (EC) 261/2004 in February 2004, airlines organised their counter-attack. Two associations seized the British High Court of Justice:

• IATA (International Air Transport Association) — representing the global air industry
• ELFAA (European Low Fares Airline Association) — the European low-cost association (Ryanair, easyJet, etc.)

Their arguments aimed to annul the Regulation entirely:

1. Incompatibility with the Montreal Convention of 1999 (governing compensation in international air transport)
2. Violation of the proportionality principle (amounts allegedly excessive)
3. Violation of equal treatment (between carriers and between passengers)
4. Violation of legal certainty (concepts too vague)
5. Insufficient reasoning of the Regulation

The British High Court submitted these questions to the CJEU.

The decision: Regulation valid on all counts

The CJEU, in Grand Chamber, fully dismisses the actions. Point by point:

1. Compatibility with the Montreal Convention

At paragraph 45, the Court clearly distinguishes the regimes:

• Montreal Convention: governs the individual contractual liability of the carrier for proven damages (baggage, injuries, delays). The passenger must prove their loss and obtains case-by-case compensation.
• Regulation EC 261: provides standardised and immediate measures (flat-rate compensation, care, rerouting) without the passenger having to prove individual loss.

The two regimes are not in competition but complementary. EC 261 therefore does not violate Montreal.

2. Proportionality

The Court holds (paragraph 80) that the obligations imposed on airlines (care, compensation, rerouting) are not excessive in light of the objective pursued: protection of passengers, considered the weak party of the transport contract.

3. Equal treatment

At paragraph 96, the Court rejects the argument that low-cost airlines are disadvantaged. The Regulation treats all carriers the same way, and economic inequalities between business models do not create legal discrimination.

4. Legal certainty

At paragraph 109, the Court validates the Regulation's concepts (notably "extraordinary circumstances") as sufficiently precise, leaving to case law the task of defining their contours over time. This will be done with Wallentin-Hermann, Krüsemann, Pešková, etc.

5. Reasoning

At paragraph 67, the Court holds the Regulation sufficiently reasoned by its recitals, which clearly set out the objective of passenger protection and the need to remedy abusive practices.

Impact: paving the way for all subsequent case law

Without IATA and ELFAA, the entire EC 261 structure would have remained fragile. This ruling:

• Locks in the principle of the Regulation against structural challenges
• Confirms cumulativity with the Montreal Convention (flat-rate compensation + individual damages can be cumulated)
• Paves the way for Sturgeon (2009): the CJEU can interpret the Regulation extensively without declaring it invalid
• Consolidates the "weak party" status of the passenger, justifying a protective regime

Cumulating flat-rate compensation + individual damages

A crucial practical consequence of IATA-ELFAA: you can cumulate.

Example: Paris-Lagos flight cancelled. You receive:

• €600 flat-rate compensation under Article 7 EC 261 (without having to prove anything)
• + Ticket refund under Article 8 EC 261
• + Reimbursement of care expenses under Article 9 EC 261 (hotel, meals, transport)
• + Compensation for proven individual damages under the Montreal Convention (loss of non-refundable hotel booking at destination, proven professional loss, etc.) — before national court

Cumulation possible and confirmed by case law.
