Yeah, but if you've got a flight that takes a set amount of time, and
one of the endpoints switches zones and the other doesn't, you'd have to
reschedule one of them anyway. Airlines are the one place I think it
_would_ make sense to schedule everything in UTC. The only situation it
wouldn't is if both endpoints make the same change (as when the whole US
changed its daylight saving rules).

Do we have any airline people here who can comment?
