In 2026, the general rule is that if an airline provides you with a full set of pajamas (loungewear) in a sealed bag or as a gift in Business Class, you are absolutely allowed to take them home. Airlines like Qatar Airways, Emirates, Qantas, and United (Polaris) consider these items a "soft product" amenity, much like the eye masks and socks in your amenity kit. They are designed to be a "take-away" souvenir and a tangible memory of your flight. However, there are a few notable exceptions: ANA (All Nippon Airways) and some other carriers operate on a "rental" or "borrow" model for their loungewear in Business Class, where the cardigans or pajamas are collected by the crew before landing to be laundered and reused. If the pajamas are presented in a high-quality reusable bag or if the crew encourages you to change into them for the flight, they are almost certainly yours to keep. If you are unsure, simply asking the cabin crew, "Are these for me to take home?" is common practice; most travelers find they make excellent, high-quality loungewear for use at home or on future trips.
