Wife had a Delta flight from JFK to DCA last night. After waiting for about an hour at the gate (sitting in the plane), they were told the flight was cancelled. They rebooked her to a flight this morning, as there were no later flights last night.
She wasn't able to get any clear answer as to why the flight was cancelled, just one of the gate agents mentioned that several flights were being cancelled and that their time on the runway got timed out (not sure if this makes sense).
Needless to say that she missed her morning meeting in DC. spent over $100 in taxis going to and back from the JFK, and also was not able to cancel her hotel reservation in DC as it was already too late.
What would be a proper compensation for such hassle?
