In 2026, United Polaris is a Business Class product, but it is currently the "top-tier" offering on United's international long-haul flights because the airline no longer offers a traditional First Class. United officially retired its "Global First" cabin several years ago to focus on the Polaris experience. While Polaris features many "First Class" amenities—such as individual lie-flat pods with direct aisle access, Saks Fifth Avenue bedding, and exclusive access to Polaris Lounges with sit-down dining—it is technically marketed and priced as Business Class. On domestic flights within the U.S., United still uses the term "First Class," but the service and seats are significantly inferior to the international Polaris product; domestic First is usually just a wider recliner seat. If you are flying between continents, "Polaris Business" is the highest level of luxury United provides, offering a refined balance of privacy and service that aims to compete with the international Business products of carriers like Delta or British Airways.
