PHX TSA wait times and how to beat the line

Where to see live security waits at Phoenix Sky Harbor, which checkpoint to use, and the free trick that lets you skip the regular line.

Where to see live wait times

Phoenix Sky Harbor posts current wait times for each checkpoint on the skyharbor.com home page, and the flight information screens inside the terminals show them too. TSA's MyTSA app also shows checkpoint waits.

Checkpoints and hours

Terminal 3One checkpoint, open 24 hours
Terminal 4, Checkpoint AOpen 24 hours (gates A1 to A14 and A17 to A30)
Terminal 4, Checkpoint B4:15am to 8:30pm (gates B1 to B28)
Terminal 4, Checkpoint C3:15am to 12:30am (gates C1 to C19)
Terminal 4, Checkpoint D3:15am to 7:30pm (gates D1 to D18)

In Terminal 4 you can use any checkpoint to reach any gate, because the concourses connect after security. If the line at your usual checkpoint is long, check the screens and walk to a shorter one. Terminals 3 and 4 are separate buildings, so you need the right terminal for your airline (see the airlines by terminal).

PHX Reserve: book a time slot for free

PHX Reserve lets you book a time to go through security, so you skip most of the regular line. It is free and you don't need an account.

  • Book up to 6 days ahead at phx.seamless.aero, or sign up at the airport using the kiosks and QR-code signs.
  • Slots run from 4 hours to 1 hour before your departure, with a 15-minute grace period.
  • It works for groups of up to 10, in Terminal 3 and at all four Terminal 4 checkpoints. Use the checkpoint named in your confirmation email.
  • It sends you through general screening. If you have TSA PreCheck or CLEAR, you are usually better off in those lanes.

TSA PreCheck and CLEAR

When PHX is busiest

  • Spring break (March) is the peak. March 2026 was the busiest month in Sky Harbor's history, with 5,128,429 passengers. The busiest single day on record was March 8, 2026, when 86,250 people went through the checkpoints.
  • Thanksgiving: the Wednesday before and the Sunday after are the heaviest days.
  • School breaks: Arizona's fall break in October and the winter holidays from late December to early January are also busy.
  • Large events like the Super Bowl push numbers up too. The previous record day was the day after the 2023 Super Bowl in Glendale.

How early to arrive

Sky Harbor's own advice for busy periods is to arrive at least 2 hours before a domestic flight and 3 hours before an international flight. On a quiet weekday with PreCheck you can usually cut that down, but on spring break weekends and holiday peaks, give yourself the full time.
