Delays and Cancellations: What to Do in Case of Disruption
Delays
If your flight from LHR to SFO is delayed, it is important to:
- Monitor the flight status via the airline’s official app or website or Heathrow’s site.
- Keep in mind that an average delay of 9 minutes should not significantly affect your experience but can obviously vary in cases of air traffic or bad weather conditions.
- Keep all receipts for any additional expenses caused by the delay to claim compensation where applicable.
Cancellations
Cancellations are a more serious event, although on the LHR-SFO route their frequency is relatively low (2.4%). In case of cancellation:
- The airline must offer you either a ticket refund or rebooking on the next available flight as soon as possible.
- You should be assisted during the wait with meals, drinks, and if necessary, accommodation.
Your Rights According to EU Regulation 261
If you depart from an airport located in the European Union, such as London Heathrow, you are protected under Regulation (EC) No 261/2004:
- Refund or alternative flight in case of cancellation or long delay.
- Financial compensation between 250 and 600 euros depending on distance and length of delay, except in extraordinary circumstances (e.g., extreme weather conditions).
- Assistance such as meals, communication, and accommodation, depending on the duration and timing of the disruption.
These rights also apply on the LHR-SFO route operated by American Airlines, as the flight departs from an EU country.
Exceptions to Know
The regulation does not cover delays under 3 hours on arrival and does not apply in extraordinary situations.
