Airport Overview

To help you plan your layover or overnight sleepover, we are here to give you the low-down on what travellers have reported back to us during their time at Houston Airport.

What to Expect

  • A large and busy airport with five terminals (Terminals A, B, C, D and E) connected by Skyway and Subway.
    Many reviewers describe the airport as dirty, chaotic and inefficient, noting the very long lines at security checkpoints and Customs/Immigration, a lack of seating, confusion at the baggage carrousels, and rude airline/airport staff. Reports are conflicting on which terminal is the worst.
  • Missed flight connections due to the very long lines at Customs/Immigration.
  • Free WiFi is available. See WiFi in the airport guide below.
  • A large variety of dining options. 24-hour dining is available in Terminal B.

Where to Sleep

  • Expect armrests on all of the seats throughout the airport. Have a travel mat or sleeping bag handy and snag a choice spot on the floor!
  • One reviewer mentioned Terminal E (Gate E8) for being a quiet and safe place to sleep (until shops open at around 5:30AM), with a strong WiFi signal and lots of power outlets and charging stations nearby.
  • Some areas of the airport are very bright and very noisy all through the night, so have a sleep mask and earplugs or noise-cancelling headphones handy for a good night’s sleep!
  • Have a travel blanket and dress warm as the terminal can get cold (day and night)!
  • For uninterrupted sleep, there are hotels near the airport that provide a free airport shuttle. See Airport Hotels in the airport guide below.

Good to Know

  • The airport is open 24 hours, but if you are not already inside the airport during night hours, you will be locked out until 4:00AM.
  • After security checkpoints close for the night, passengers are restricted to landside only. Passengers sleeping airside will be required to go back to landside until security reopens, and will need to clear security again to re-enter.
  • Economy class passengers can pay to use one of the first class lounges. See Airport Lounges in the airport guide below for locations and rates.

Airport Hours

While the airport is open 24 hours, it only remains open to ticketed passengers already within the terminal who have been stranded or arrived late at night and await connecting flights in the morning.

If you are a traveller looking to spend the night inside the airport prior to an early morning flight, the terminal doors are locked to outsiders. According to a review we received on March 25, 2016 from a traveller at Terminal C it was not possible to enter overnight. The reviewer tells us " You say that the airport is open 24h. It is just not true. They close the doors for the night hours. If you are already in, its OK, but from the outside you can't get in during these hours. If your ticket is for the next calendar day, they dont let you in and have to wait until 4 AM. In this case, you should be prepared to wait outside the terminal or make other arrangements.

Keep in mind that airline check-in and baggage drop hours vary according the flight schedule. Check these hours with your airline. If you are in the public area of the terminal (landside) you will not be able to get through to the secure area of the terminal (airside) until the morning. The TSA security screening checkpoint hours vary according to terminal:

  • Terminal A North: 4:30AM - 8:00PM
  • Terminal A South: 3:30AM - 10:30PM
  • Terminal B: 5:00AM - 9:00PM
  • Terminal C North: 4:30AM - 7:00PM
  • Terminal C South: 4:00AM - 11:00PM
  • Terminal D: 4:00AM - 12:30AM
  • Terminal E: 4:30AM - 12:01AM
