Trtl Pillow Plus - Airplane Neck Pillow for Traveling - Height-Adjustable, Breathable Travel Pillow for Head and Neck Support While on Planes, Cars, and Trains - Machine Washable

Neck pillows are more personal for each person so it'll be harder to determine but you do have a bit of time to try it out and return before your trip. Personally I use this pillow due to how it can mold to whatever shape I want and bunch up the beads to go toward the side of my head which I lean on https://amzn.to/3TLP9eV SO finds my pillow a little discomforting due to how the beads can move but likes this adjustable trtl pillow to keep the neck up with your head only slightly tilted vs the beaded pillow https://amzn.to/4ejEuAm I don't like the stiffness of the trtl which emphasizes how personal the neck pillow can be. So try what neck pillows seem interesting to you at home while watching TV, in the car, or wherever you can take a nap to see how comfortable it can be for you. Hope you find one you like and those that you don't you can return as long as you keep the original packaging to return it with.
