Another option could be something like Nreal Air AR Glasses. You are supposed to be able to connect to a PC and have a 200" screen in front of you. I don't have one so I can't tell you how good it is. I do, however, has a Meta Quest 2 and the virtual big screen is really nice. I am not taking that to a flight though because it looks really weird wearing one with other people around. The AR glasses seems like it would be something less nerdy looking.
