Despite the fact that American Airlines is not a European carrier, they follow European laws whenever they fly in Europe. That's great news for passengers who have been stranded due to a flight cancellation, because a last-minute cancellation of a European journey may entitle them to a fair American Airlines compensation settlement. If an American flight cancellation, you will be provided an alternative ticket to your destination or a full refund if you want. Furthermore, if your flight was cancelled less than 14 days before it was scheduled to depart a European airport, EU guidelines provide that passengers may be eligible to compensation of up to £510 per person. If American Airlines was able to provide you with a different flight, They won't have to compensate you because it will land at a pretty similar time to your original.
