Before heading to the airport, passengers can save time by knowing the Southwest Airlines Rick Husband Amarillo Airport Terminal location. Southwest uses the Main Terminal at Rick Husband Amarillo International Airport for its passenger services. Travelers can check in, handle their luggage, pass through security, and then continue to the appropriate boarding gate. Gates 6 and 7 are generally used for Southwest flights at AMA. Since airport information can change, passengers should confirm their gate and flight status before departure. Arriving early is recommended so there is enough time for check-in, security, and boarding.
