- its because the airline request it, to make their on-time departures look better rather than sit at the gate and show 'a delay'
I kind of figured that was the case. But I'm sure it's only a matter of time before someone loses it and decides to pop an exit hatch and escape his "captors." Once I spent 3 hours on the ground at DFW with no A/C and I can tell you that it sure crossed my mind. Luckily I was still sane enough to think of what a royal mess that would have caused and how long I would probably have spent in jail.
