Inputting a trusted traveler identification into an already-made American Airlines flight booking allows passengers to potentially access expedited security screening programs like TSA PreCheck. This process typically involves accessing the reservation online, through the airline’s mobile application, or by contacting customer service and providing the trusted traveler number. For example, a passenger who initially booked a flight without including their Global Entry number can later update their reservation to reflect this information.
The inclusion of this identification can offer significant advantages, such as reduced wait times at airport security checkpoints. Historically, security lines have been a major source of stress and delay for air travelers. Programs like TSA PreCheck aim to alleviate this by providing a faster screening process for vetted individuals. Adding the relevant information to an existing reservation ensures that the boarding pass is correctly flagged for PreCheck eligibility, assuming all other requirements are met.
