Was on AA flight120 on 11/20 from JFK-CDG for a week vacation (treating my mother for her birthday), when our flight was diverted to Gander, Canada due to electrical system malfunction. We were stuck in Gander for roughly 12 hours while a new plane was flown in from JFK with new crew. AA did put us up in a local hotel for a 5 hours while we waited from 2:30AM-9:00AM before being taken back to the airport. We then waited for 4 more hours as the new plane taking off from JFK was delayed before being able to finish the flight to CDG. What is fair compensation for losing 1 day of the vacation along with non-refundable tickets (30 euros) and one night non-refundable hotel in Paris? If it matters, we were flying International Business Class ("I" fare I think). I'm not greedy and I'm very grateful that we made it here safely. However, I do feel something is owed and am wondering what is considered fair? Any help would be appreciated.
