Absolutely. Amenity kits in First and Business Class are considered gifts for the passenger to use during the flight and keep as a souvenir. In fact, airlines often partner with luxury designers like Armani, Tumi, or Missoni to create these kits specifically so that they are high-quality enough to be reused for storing cables, makeup, or travel documents after the trip. Inside, you will usually find travel-sized skincare (lotions and lip balms), a dental kit, eye shades, earplugs, and sometimes even high-end socks or pajamas. While items like the pillow, blanket, and headphones must stay on the aircraft, the amenity kit pouch and everything inside it are yours to take. Many frequent flyers collect these kits or donate unopened ones to local shelters, where the travel-sized toiletries are highly valued for those in need.
