My husband (US citizen) traveled from Mumbai, India, to Cleveland, OH, via Newark. The Mumbai-Newark flight was delayed just over 8 hours due to crew availability. (Scheduled departure 11:20 pm, actual departure 7:30 am the next day).
Once on the Mumbai-Newark flight, they had to make an emergency diversion to Stockholm, complete with an emergency fuel dump, due to a passenger medical emergency. A passenger and a flight attendant left the plane. The crew announced refueling, and that they had to wait for the flight attendant to return, as they did not have a replacement and FAA rules required them to have 10.
This took 3 hours. They arrived to Newark 11 hours 45 minutes later than they should have. What compensation is required by law, and what laws apply?
