4. Adjust the headrest
If you’re not provided with a neck pillow and if you’re not carrying one either and you happen to be on a plane with adjustable headrests then you’re not completely doomed. You can simply fold the flaps inward to keep your head from rolling back and forth. Try to secure an airplane pillow when you board, fold it in half and place it on one of your shoulders. This will give your head a place to rest comfortably working as a backward U-shaped pillow.
