Saving your DoD ID Number as part of your profile will prevent you from having to enter it each time you make an airline reservation. It also ensures that it is included in all future reservations. It is important to note that updating your profile with your DoD ID Number will only qualify you for expedited screening for new reservations; it does not apply to existing reservations.

If it is at least 72 hours prior to scheduled flight departure, you may still be able to add your DoD ID Number to your existing reservation.
