TSA Security Checkpoints: Passengers departing on Southwest, Sun Country, United and Via Air airlines enter the A Gates at the east side of the ticketing level. Passengers departing on Alaska, American and Delta airlines enter the B gates at the west end of the terminal. Passengers with boarding passes who are not checking bags or otherwise need to check-in at an airline counter, may want to be dropped off at the entrance to their concourse. The Concourse B entrance near the first doors as you approach the terminal and the Concourse A entrance is adjacent to the last doors as you leave the terminal area.
The Transportation Security Administration security checkpoints at Tucson International Airport open by 4 a.m. daily or earlier if flight schedules warrant. They close when the last flight of the day departs. Wait times are usually less than 10 minutes except during busy times early in the morning before 8 a.m. and mid-day from about 11:30 a.m. to 1 p.m. (Please note: Tucson does not observe Daylight Saving Time and airlines adjust their schedules accordingly. From November until early March when Standard Time is in effect in the United States, the busy times are an hour later.)
Information regarding the checkpoint process can be found at the Transportation Security Administration’s website.
Specially designated lanes on both the A and B Concourses allow passengers who have been qualified through U.S. Department of Homeland Security programs including TSA Pre✓, Global Entry, SENTRI and active duty military personnel to use expedited screening. Passengers who qualify for this will have it noted on their boarding pass with a reference to TSA Pre✓. At times when there are not sufficient passengers the TSA may close the PreCheck queueing lane and/or screening equipment. At those times, the document checker will direct qualified passengers how to proceed through the screening process. In some cases, the PreCheck equipment may still be used and at other times passengers will have to go through the regular screening lane and are permitted to wear their shoes but will be required to remove laptops and similar devices from carrying cases.
Personnel are prepared to assist passengers using wheelchairs or strollers and their traveling companions, including service animals, through the TSA checkpoints. Passengers being dropped off and needing wheelchair assistance should request that assistance when making their airline reservations. Due to security regulations, the airport cannot permit drivers to leave their vehicles unattended at the curb while assisting passengers into the terminal.
