TSA Security Checkpoints: There are separate TSA security checkpoints for the C, B and A gates, which are not connected post-security. Passengers departing on Allegiant enter the C gates checkpoint from the breezeway at that facility, which is the first you come to as you enter the terminal area. Passengers departing on Alaska, American and Delta enter the B gates at the west of the departures level of the main terminal. Passengers departing on Frontier, Southwest, Sun Country, United and Via Air enter the A Gates at the east side, or the last gates, of the main terminal.
The Transportation Security Administration checkpoints in the main terminal at Tucson International Airport open by 4 a.m. daily or two hours before a scheduled flight. They close when the last flight of the night departs. The checkpoint at the C gates is open only when flights are scheduled from that building. Wait times are usually less than 15 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 at the entrances to both the A gates and B gates 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 on how to proceed through the screening process. In some cases, the PreCheck equipment may still be used and at other times passengers will go through the regular screening lane and permitted to wear their shoes but will be required to remove laptops and similar devices from carrying cases. TSA PreCheck✓ is not currently available at the C gates checkpoint.
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.
