Yes, you can access a United Club after landing in 2026, but only under specific conditions. If you have a standard United Club membership (annual or through a credit card), you are permitted "same-day" access upon arrival, provided you have a valid boarding pass from your just-completed United or Star Alliance flight. However, if you are attempting to access the more exclusive United Polaris Lounge, arrival access is generally restricted to passengers who have just completed a long-haul international flight in Polaris Business Class. For those using a "One-Time Pass" (often provided by the United Explorer card), the rules have become stricter; these passes are primarily intended for departure or connecting flights and may be restricted at arrival if the lounge is near capacity. It is also important to note that most lounges are located "airside" (past security), so you must enter the lounge before you exit the secure area to claim your checked baggage, as you cannot re-enter the terminal without a departing ticket.
