Uncomfortable experience with cancelation and waiting. Waiting in the airplane and sleeping at the airport with my children without delta support, rebooking was ok, next day at 01.00 pm but changed the gate many times and delay flight delays again and now it is more than 3 hours again inside airplane and don't know what will happen next. Yesterday we was inside airplane about 3 times before cancelation. It looks like they don't care about theirs passengers. After what happened yesterday, today's booking should be better. What about all of our appointments and booking in LAX? I am talking about flight from JFK airport to LAX. I am feeling no one is hearing.
