Depends on where you sit. But with skirt that short, you'd be flashing panties all over the place just by bending over to move the seat belt out of the way, bending over to put your bag under the seat in front of you, bending over to scooch under the overhead bins to get to your seat, and so on. If she sat in the aisle, she'd flash if she got up to go to the bathroom or just walk around or to deboard the plane. (And if she sat by the window, she'd flash the guys outside when she got up to deboard.)
that’s ridiculous
