How early should I get to PHX?

PHX posts live checkpoint wait times on the skyharbor.com homepage and terminal flight information screens; it publishes no typical wait figures.

Nationally, TSA checkpoints are busiest from 5 to 7 AM local time. See TSA's hourly numbers and the busiest days to fly.

TSA PreCheck: PreCheck hours are limited: Terminal 3 from 5 a.m.-2 p.m., and all Terminal 4 checkpoints (A-D) from 5 a.m.-7 p.m., subject to change. Outside those hours, PreCheck travelers go through regular screening. Free PHX RESERVE appointments (book up to 6 days ahead, for 60-240 min before departure) are for general-screening passengers only.

CLEAR: Available at this airport (see terminals below for which checkpoints).

Touchless ID: PHX is on an April 2026 list of 65 airports with TSA PreCheck Touchless ID; participating airlines there were not specified. Opt in with your airline.

Between terminals: The free PHX Sky Train runs 24/7 between Terminals 3 and 4, both Economy lots, the Rental Car Center and the 44th St Valley Metro Rail station. Waits average about 3.5-7 minutes from 5 a.m. to 10 p.m. and can be 15+ minutes during nightly maintenance (10 p.m.-5 a.m.). Passengers changing terminals must be screened again.

Terminals are not connected after security. Go to the right terminal the first time.

Rideshare and taxi: Uber, Lyft, Wridz, Waymo and HUM serve PHX. Pickups are on the Terminal 3 outer curbs and Terminal 4 Level 1 outer curbs (doors 1, 2, 6, 8). Waymo picks up and drops off at each terminal's rideshare location 24/7. PHX suggests using the 24th St or 44th St PHX Sky Train stations for drop-offs to avoid terminal traffic.

Transit: Valley Metro Rail connects directly to the PHX Sky Train at the 44th St & Washington station, with access to Phoenix, Tempe and Mesa. Bus Route 13 stops at the 24th St Sky Train station and Route 44 at the 44th St station. PHX does not publish a downtown travel time.

Driving and parking: Expect construction on Sky Harbor Boulevard: a realignment took effect Oct 10, westbound west-airport traffic is down to a single lane (since Aug 14), and Terminal 3 has indefinite overnight lane restrictions. Reserve parking in advance, and use the free 24-hour cell phone waiting lots.

• Terminal 3 North Concourse (six new gates) under construction, completion expected 2027. Overnight lane restrictions on Sky Harbor Blvd at Terminal 3 are indefinite, and at times the Terminal 3 garage can be entered and exited only from the south side via westbound Sky Harbor Blvd.
• Eastbound and westbound Sky Harbor Boulevard realignment on the west side of the airport took effect Oct 10
• Taxiway Uniform project: westbound Sky Harbor Blvd on the west end reduced to a single lane since 5 a.m. Aug 14, until further notice; eastbound Sky Harbor Blvd rerouted beneath the new taxiway bridge. PHX advises planning for longer travel times.
• PHX Sky Train nightly maintenance from 10 p.m.-5 a.m. can mean 15+ minute waits; staged buses run from 44th St Station to the Terminal 3 and Terminal 4 curbs
• Sept 21, 2026: PHX named American Airlines the primary carrier for a future West Terminal (Destination PHX 2050); no 2026 passenger impact announced

Delta: bags at least 45 min before departure, check-in at least 30 min without bags, at the gate 15 min before. Southwest: bags 45 min, check-in 30 min (domestic). Alaska: check-in and bag drop typically close 40 min before. At PHX, Frontier closes ticket counters 1 hour before departure and Porter 90 minutes before. Free Early Bag Check (Rental Car Center and East Economy, 5 a.m.-5 p.m.) requires bags at least 90 minutes and no more than 4 hours before departure, for domestic flights on Alaska, American, Delta, Frontier, Southwest and United.

• PreCheck lanes close early (2 p.m. at Terminal 3 and 7 p.m. at Terminal 4). On evening flights, plan for standard screening or book a free PHX RESERVE slot.
• Book PHX RESERVE up to six days ahead for a dedicated general-screening lane; appointments have a 15-minute grace period
• Terminals 3 and 4 are not connected after security, so confirm your terminal: Southwest and American use Terminal 4, while Delta, United and Alaska use Terminal 3
• Returning a rental car or parking at East Economy? Free Early Bag Check (5 a.m.-5 p.m.) lets you drop domestic bags before taking the Sky Train
• Late-night Sky Train trips can involve 15+ minute waits during nightly maintenance (10 p.m.-5 a.m.), so add buffer time
• Frontier's ticket counters at PHX close 1 hour before departure, earlier than most airlines
