United Airlines Introduces Base Polaris Fare to Expand Premium Cabin Access

United Airlines is overhauling its premium cabin fare structure by introducing a new 'Base' fare for its Polaris business class and Premium Plus cabins. The move, set to begin this spring, aims to make high-end travel more accessible while segmenting the market with varying levels of flexibility and perks. The Base fare includes access to lie-flat seats in long-haul business class but requires passengers to pay extra for seat selection, limits checked baggage to one bag, and restricts lounge access to the United Club instead of the more luxurious Polaris lounges. Changes to the ticket are not permitted under this fare class. Alongside the Base fare, United is offering 'Standard' and 'Flexible' fare tiers for Polaris, with the latter providing access to the new Polaris Studio suites featuring sliding doors and larger screens. This strategy mirrors the segmentation seen in economy class, where airlines have long offered basic economy and premium economy options with added fees. The overhaul coincides with a broader upgrade to United's Polaris cabins, which have been in service for nearly a decade. The airline is also applying similar fare segmentation to its Premium Plus premium economy class, with new options rolling out in select markets this month and expanding to international and long-haul domestic routes later in 2026. United's approach reflects a growing trend among airlines to maximize revenue by offering tiered premium experiences, a strategy that could influence competitors like Delta Air Lines, which has also considered similar changes. A United spokesperson noted that Base Polaris passengers will receive the same meals, including ice cream, as other premium cabin travelers, but declined to specify pricing differences between fare tiers. The airline emphasized that the Base fare is intended as an entry-level option to attract a broader customer base to its premium offerings.
