The question of whether airplane blankets are "free" has two parts: are they free to use, and are they free to take? In 2026, most full-service airlines (like Emirates, Lufthansa, or Delta) still provide blankets free of charge for use during the flight on long-haul international routes. However, these blankets are the property of the airline and are meant to be laundered and reused; taking them home is technically considered theft and can lead to a fine or being blacklisted, though this is rarely enforced. On the other hand, many budget airlines (like Spirit, Ryanair, or JetBlue's basic fares) may charge you a fee to "rent" or buy a blanket pack. Some airlines, particularly in First or Business Class (like ANA or Qatar), occasionally provide high-end amenity kits or sealed "travel sets" that are explicitly gifted to the passenger. If the blanket is in a sealed plastic bag and looks like a disposable or personal travel kit, you might be able to keep it, but it is always best to ask the flight attendant. For most economy passengers, it's safer to assume the blanket must stay on the plane.
