United Airlines offers a place for passengers to relax before or after their flight. The United Club^? lounge is available to United Club members, Star Alliance Gold members, passengers traveling in United Polaris business class or United first class, or passengers who purchase a one-time pass.

On United Airlines, a standard domestic First Class ticket does not typically grant access to the United Club. This is a common point of confusion for travelers; in the United States, "Domestic First Class" is treated as a premium cabin for flight service but not for lounge privileges. However, there are significant exceptions: you do get access if you are flying "United Business" on a premium transcontinental route (such as between New York/Newark and Los Angeles or San Francisco). Additionally, international travelers flying in United Polaris℠ business class or International Business Class have full access. For those flying strictly domestic First Class without a premium route designation, access is only granted if the traveler holds a separate United Club membership, a high-tier Star Alliance Gold status, or is using a one-time pass. In 2026, United has maintained these strict barriers to prevent overcrowding in their lounges, focusing their "complimentary" access exclusively on long-haul international flyers and those on their most lucrative transcontinental "business" routes.
