I am about to fly on a Delta 767 (domestic), so this pertains to this specific airline and plane type.
Do they allow you to use a laptop computer during flight? Which parts of the flight is it not allowed? do Delta's 767-300, 767-200, and MD11 have power outlets in COACH section?
I know this is kinda off topic and I hope the mod's won't delete it, but if you do not use a power plug, how long can you expect battery life to last on a compaq laptop (newer model Li-Ion battery) assuming no CD burning, no downloading..mainly use for flight tracking.
