# EU261, Explained

The regulation only ever mentions cancellation and denied boarding — the right to be paid for a long delay comes from a court, not the text itself.

EU261 (Regulation (EC) No 261/2004) entitles passengers to fixed compensation — €250 to €600 — for a cancelled flight, an involuntary denied boarding, or (per later CJEU case law) a delay of 3+ hours at arrival, on any flight departing an EU/EEA/Swiss airport or arriving there on an EU-licensed carrier — unless the airline proves the cause was a genuinely extraordinary circumstance.

EU261 is the common name for Regulation (EC) No 261/2004, the EU law on compensation and assistance
for airline passengers. It's one of the most litigated pieces of EU consumer legislation, largely
because the version enforced today is significantly bigger than the version actually voted into law.

## What the text itself says

Three situations, three articles:

- **Article 4 — Denied boarding.** If you're bumped from an oversold flight against your will, the
  airline "shall immediately compensate" you per Article 7. No excuse is written into this article
  at all.
- **Article 5 — Cancellation.** Compensation is due unless the airline gave enough advance notice
  (14+ days, or less with a tight enough replacement flight) or proves "extraordinary circumstances
  which could not have been avoided even if all reasonable measures had been taken."
- **Article 7 — The amounts.** €250 for flights of 1,500km or less, €400 up to 3,500km, €600 beyond
  that, measured by the great-circle distance between the airports.

Notice what's missing: a flight that's simply delayed, but not cancelled, gets no mention at all in
the operative articles. The regulation's Article 6 only requires the airline to provide meals, hotel
and communication for a long delay — not money.

## What the courts added

In 2009, the Court of Justice of the EU decided *Sturgeon v Condor* (C-402/07) and a companion case
together. The reasoning: a passenger who arrives 3+ hours late has lost essentially the same time as
one whose flight was cancelled and rebooked, so denying the delayed passenger compensation while
paying the cancelled one would treat comparable situations unequally — a breach of the general EU
principle of equal treatment. The Court reinterpreted Articles 5-7 to apply "mutatis mutandis" to
long delay.

This is why "the EU261 3-hour rule" is common knowledge despite not appearing anywhere in the
regulation's own text — it's the practical effect of that single, still-controversial judgment
(airlines challenged it repeatedly; the CJEU reaffirmed it in *Nelson v Lufthansa*, C-581/10, in
2012).

## The extraordinary-circumstances fight

Nearly every disputed EU261 claim comes down to one question: was the cause "extraordinary"? The
regulation gives examples in its recitals — political instability, unsafe weather, security risks,
strikes — but the real boundaries were drawn case by case:

- **Technical faults are (mostly) not extraordinary.** *Wallentin-Hermann v Alitalia* (C-549/07,
  2008) held that fixing a technical problem is inherent in running an airline, with a narrow
  exception for a hidden defect affecting a whole aircraft type.
- **The airline's own staff striking is not extraordinary**, even a wildcat strike its management
  didn't organise (*Airhelp v SAS*, C-28/20, 2021) — a third party's strike (air traffic control,
  airport staff) generally is.
- **The burden of proof sits with the airline**, not the passenger. An airline that simply asserts
  "technical issue" without evidence hasn't discharged that burden.
