In 2026, American Airlines (AA) provides lounge access for First-Class passengers, but the type of lounge depends heavily on your specific "ticketed itinerary." If you are flying Flagship First on a qualifying international or transcontinental route (e.g., LAX to JFK or DFW to London), you gain access to the premium Flagship Lounge and the exclusive Flagship First Dining area. However, a standard domestic First-Class ticket for short-haul flights (e.g., Miami to Atlanta) does not typically include Admirals Club access unless you have a separate membership, high-level AAdvantage status, or a qualifying credit card like the Citi® / AAdvantage® Executive. For international travelers, the "First Class" designation on a short-haul leg that connects to a long-haul Flagship flight usually grants access for the entire journey. Always check your digital boarding pass in the AA app, as it will explicitly state "Lounge Access" if your fare class and route combination qualify for entry into the Admirals Club or Flagship facilities.
