it happened to me once at LGA a year ago when complete
northeast coast was under heavy snow storm. I was on a
ATA B727-200 on my way back to MDW and we were number
38 for takeoff. We were on the taxiway for little over 2 hours
due to heavy traffic out of all major NY airports. I guess
the flight control in NY area was restricting the airports for
letting them to permit only certain number of aircrafts to take
off or something... Well, that's what the captain told us...
Since ATA does not serve anything, but drinks, they were serving
only water while we're on the ground between the time of
5:30pm until 7:30pm, most of passengers were very hungry and
tired...
