Of course, all United Polaris customers are welcome to take their amenity kits featuring Cowshed products with them at the end of the flight. Slippers and pajamas — on flights where they are offered — are also available for customers to take with them.

Yes, you are absolutely allowed—and even encouraged—to keep your United Polaris slippers. These slippers are considered a "single-use" amenity provided for your comfort during long-haul international flights. Once they are removed from their plastic packaging, the airline cannot reuse them for another passenger due to hygiene reasons. Many frequent flyers keep them as souvenirs or to use as lightweight house shoes after their trip. The slippers are part of the premium Polaris experience, which also includes Saks Fifth Avenue bedding and Therabody amenity kits. However, you should be aware that the bedding (pillows and duvets) and the Saks Fifth Avenue blankets are not complimentary and must remain on the aircraft; taking them is considered theft and can result in being charged or flagged by the airline. The slippers, along with the contents of the amenity kit (eye masks, earplugs, and skincare items), are yours to take. Some travelers even grab an extra pair from the Polaris Lounge shower rooms to provide for guests at their homes, though they are famously "flimsy" and rarely last more than a few days of consistent use.
