American Airlines has launched its new sleeper service globally in partnership with bedding company Casper.

Available from today, customers seated in long-haul international and transcontinental First or Business class and Premium Economy can enjoy a suite of advanced sleep offerings designed by Casper’s award-winning engineering team.

The Casper line of sleep products will include a mattress pad, duvet, pillow, day blanket, lumbar pillow, pyjamas and slippers, with the exact offering varying based on the route.

American Airlines’ new First Class bedding offering

Casper researched more than a dozen versions of the on-board pillow and tested it with a variety of fibres to find the perfect balance of support and breathability for customers.

Inspired by performance outerwear, Casper’s signature duvet and the on-board duvet are created to provide comfort at all altitudes, and its sewn-through seams create small, rectangular chambers for a consistent fill distribution to stay fluffy and in place.

American put these designs to the test with customers on some of its longest flights, including Los Angeles to Auckland, New Zealand.

The airline also tapped the expertise of some of its most frequent travellers, its flight attendants, for advice on fit, durability and comfort.

“Customers and crew members who tried Casper on our flights said they loved it,” said American Airlines Senior Vice President for Marketing, Loyalty and Sales, Kurt Stache.

“Casper has set a new standard for premium sleep products and our new line showcases their attention to detail and design, and their commitment to providing the best rest possible for American Airlines customers.”

Casper was founded in 2014 with the mission of improving sleep and modernizing the mattress industry. This is the first time Casper has applied its sleep expertise beyond the home to the world of travel.
