On my last flight, I noticed that I kept falling asleep with my mouth hanging open. I like that this has a chin strap, and each part is adjustable to fit your head. I am not sure how I will be able to attach it to the airplane seat whenever I go again, but it works for car seats, and we tend to drive to locations more than fly anyway. It folds up into a little travel pouch and is easy to take with you. My husband thinks it's nice. He turns into a bobblehead whenever he tries to sleep in cars.
