Yes, you can absolutely take pillows in your suitcase, and there are no TSA or airline security restrictions against them. Since pillows are mostly air and fabric, they are perfectly safe to fly. The main challenge is the physical space they occupy. In 2026, many frequent travelers use vacuum-seal compression bags to shrink a standard bed pillow down to about 20% of its original size, allowing it to fit easily into a checked suitcase or a carry-on. If you don't want to pack it, many airlines allow you to carry a pillow as your "personal item" or even as a "free" extra, though this depends on the gate agent's discretion. Small neck pillows or "travel pillows" do not count toward your carry-on limit on most airlines if you are wearing them around your neck during boarding. If you are packing a specialized medical or orthopedic pillow, it is a good idea to keep it in your carry-on in case your checked luggage is delayed, as these can be difficult and expensive to replace while on vacation.
