Yes, you are absolutely permitted to keep the pyjamas provided in First Class and select Business Class cabins on long-haul flights. In 2026, these high-fidelity loungewear sets are considered a high-value "take-home" amenity, much like the items in your amenity kit. Airlines like Emirates, Qatar Airways, and Virgin Atlantic design these pyjamas to be high-value souvenirs of your "High-Fidelity" premium experience. However, there is a high-fidelity exception: some carriers, particularly ANA (All Nippon Airways) and occasionally Japan Airlines, may provide cardigans or "relax wear" that are intended for onboard use only and must be returned. For 2026 travelers, a high-value "pro-tip" is that if the pyjamas are presented to you in a sealed bag or box, they are almost certainly yours to keep. These high-fidelity sets are often made of high-value sustainable cotton or bamboo, making them a high-fidelity and practical addition to your home sleepwear collection long after your high-value journey has ended.
