DJ MOM: I mostly read books on the plane. But I did watch 1 movie and I had plenty of charge left. We did have a really LONG fling (Kauai). Maybe look at the apple web site to see how long the battery lasts. Also, at the condo we all used it and only charged it in the evening.
I've flown Midwest a few times. Great service, seats are nice, love the extra leg room and the best part is the cookies! Worth the extra hr drive to Milwaukee too fly them.
