I’ll admit that I’m a germaphobe, but these airplane seat covers are a bit much, even for me. Not only does this kit come with covers for the seat, it also includes armrest and tray table covers and a disinfectant wipe. If it makes you feel better, why not? I would expect some strange looks from fellow passengers though. They come in disposable and reusable/machine washable versions.
