Pillows. Just like with blankets, if you're offered a pillow during your flight you need to leave it when you're leaving. “It's for in-flight comfort, not a freebie to take home,” says Deane.

Generally, the answer is no, you cannot take the pillows provided by the airline, as they are considered the property of the company and are intended to be laundered and reused for future flights. This is especially true for the high-end, branded pillows found in First and Business Class. Taking them can technically be considered theft, though most airlines rarely enforce this with small, low-cost economy pillows. However, in 2026, many travelers prefer to bring their own personal neck pillows, which are explicitly allowed as "personal items" and do not count toward your carry-on limit on most airlines like Southwest or Delta. If an airline provides a "disposable" pillow (usually wrapped in thin plastic) on a long-haul flight, it is still intended to stay on the plane. If you truly love the comfort of a specific airline's bedding, many carriers now sell their signature pillows and blankets through their online "Boutique" stores.
