Blankets. Business and first-class flights offer comfort items like blankets during the flight. You must leave them on board when you're leaving the plane as they can be reused.

As of 2026, the general rule remains that you cannot take airline-provided blankets home. These items are considered company property intended for reuse; after each flight, they are typically collected, laundered, and repackaged for the next set of passengers. Taking them is technically considered theft, though most airlines rarely prosecute for a single blanket. However, many modern airlines have moved to a "sustainability-first" model where they may sell high-quality, branded blankets in their "Duty Free" or "In-Flight Shop" catalogs for passengers who wish to keep them. If you are provided a disposable, thin fleece blanket in a sealed plastic bag on a low-cost carrier (which you may have paid for as an "amenity kit"), those are often yours to keep. For standard long-haul blankets in Economy or the high-end duvets in First Class, they must stay on the aircraft. To avoid confusion, 2026 travel experts suggest bringing your own compact travel blanket, which is more hygienic and guaranteed to be yours.
