About 2 to 4 weeks prior to departure, American Airlines requires the final payment and passenger list for your group. This marks the transition from planning to preparation. At this stage, group discounts have already saved you from fare hikes, and your agent can assist with seat assignments, special requests, or baggage arrangements. You may also be allowed limited last-minute name changes, depending on your agreement. This period is crucial for ensuring all travelers are ready and accounted for, and American’s group desk remains available for any last-minute adjustments or support.
