What's the best way to sleep on a plane?
That's helpful. Do you think it's better to sleep leaning against the window or in the middle seat?
It's usually better to sleep leaning against the window because you can have something to rest your head against. However, if you can't get a window seat, the middle seat isn't necessarily bad if you can lean on the armrests or use a pillow to prop yourself up.
