I sometimes watch those programmes too, recently the Airport USA featuring Southwest.
Thing that always annoys me is the passengers who chuck their toys out of the playpen when they turn up late and can't get on the plane. Everyone knows that you need to be there in plenty of time, yet on every flight there seems to be at least one person who gets there 10 mins after gate is shut and then goes off on one at all and sundry, when its their own stupid fault for not allowing enough travel time to get to the airport.
Whenever I see these programmes I have an irresistable urge to smack the offending passenger in the mouth, how the staff in situ don't really amazes me cos they must have the patience of saints.
