United Airlines officially offers United First® as its premier cabin for domestic flights within the U.S. and for short-haul international routes to Canada, Mexico, the Caribbean, and Central America. In 2026, this cabin features wide, ergonomic leather seats, priority "Premier Access®" at the airport, and complimentary hot meals on flights over 800 miles. For long-haul international flights, however, United does not use the "First Class" branding; instead, it offers United Polaris® business class, which features lie-flat pods with all-aisle access and luxury Saks Fifth Avenue bedding. A new "Polaris Studio" product is debuting in 2026 on select Boeing 787-9 aircraft, offering an even more elevated "First-class lite" experience in the front rows. This naming convention can be confusing for travelers: if you are flying from Chicago to Los Angeles, you book "First Class," but if you are flying from Chicago to London, the top tier is "Polaris." Both cabins offer elevated service and free alcoholic beverages, but only the international Polaris product provides a full lie-flat bed and access to the exclusive Polaris Lounges.
