In 2026, the short answer is yes, airlines do reuse blankets, but they are almost always professionally laundered and hermetically sealed in plastic between flights. After a flight lands, cleaning crews collect used blankets and pillows, which are then sent to massive industrial laundry facilities to be washed at high temperatures to kill bacteria and viruses. They are then folded and "shrink-wrapped" to signify to the next passenger that they are fresh. However, there is a "tiered" reality to this: on many short-haul domestic flights, blankets are not provided at all or may only be "refolded" rather than laundered if time is tight between turns. For the highest hygiene standard, blankets in First and Business Class are often higher quality and undergo more rigorous cleaning. It is a peer-to-peer "pro-tip" that if a blanket is not sealed in plastic when you find it on your seat, it may have been left over from the previous passenger. For this reason, many frequent flyers in 2026 prefer to carry their own lightweight, packable travel blanket for guaranteed cleanliness and comfort.
