Passenger Rights under EU Regulation 261
For passengers departing from an airport in the European Union, such as London Heathrow, Regulation (EC) No. 261/2004 protects rights in case of delay or cancellation. Here are the main protections for those flying from LHR to LAX with AA:
-
Delay:
- If the flight arrives more than 3 hours late, passengers are entitled to financial compensation ranging from €250 to €600, depending on the distance (the LHR-LAX route falls in the >3500 km category, so up to €600).
- In the case of a significant delay, passengers must receive assistance (meals, communication, and if necessary, accommodation).
-
Cancellation:
- If the flight is canceled, the passenger can request a full refund of the ticket or an alternative flight to the destination at no extra cost.
- If the cancellation was not communicated at least 14 days in advance, a financial compensation similar to that for long delays is due.
-
Exceptions:
- Airlines are not obliged to pay compensation if the delay or cancellation depends on “extraordinary circumstances” such as extreme weather or unpredictable strikes.
Remember that, for flights departing from EU airports, these rights apply regardless of the operating airline.
