What are passengers owed when a Delta Air Lines qualifies?
Under Regulation (EC) No 261/2004, a delay of three hours or more at arrival, or a late cancellation, can mean €250, €400 or €600 per passenger, by distance. Delta Air Lines compensation follows the same rules as any other airline's. The airline can still refuse for extraordinary circumstances, such as a storm. Delta Air Lines cancellations count from the day the airline cancels; the notice it gave decides each claim.

- Read the EU261 guide in plain language.
- Read our Delta Air Lines guide.
- Start a claim if your own flight was one of them.
The rules will change. The European Parliament approved a reform of EU261 on 7 July 2026, expected to apply from the second half of 2027. Until then the current rules stand.
How were these Delta Air Lines figures made?
We record the scheduled and actual times of passenger flights at a panel of monitored airports. A flight qualifies when it arrived three hours or more late, or was cancelled. Qualifying is not the same as owed. The panel is a sample, so every count is a floor, not the whole market. A codeshare counts once, under the airline that operates it. The monthly release explains the method in full.
