What makes Polaris lounges different from United's normal lounges? For starters, they're exclusively for passengers traveling in Polaris business class on United (or business or first class on a Star Alliance flight) for a long-haul international flight.

Seat Locations United Polaris seats are located at the very front of the aircraft, allowing you to be the first on and first off. These seats are in a private cabin in the aircraft, with separate lavatories from the Premium Plus and economy cabins, creating less foot traffic throughout the flight.

Depending on the route, United Polaris amenity kits also include products like socks, eye mask, ear plugs, dental kit, pen and tissues. United Polaris passengers get Saks Fifth Avenue bedding. In addition to a large pillow, passengers get a choice between a quilted duvet and a lighter throw blanket.
