IAH Airport Overview

To help you plan your layover or overnight sleepover, here is a quick run-down about what to expect during your time at Houston George Bush International Airport.

What to Expect

Houston George Bush International Airport (Code: IAH) consists of five separate terminals (Terminals A through E) interconnected by Subway (Landside) and the Skyway (Airside), allowing passengers with inter-terminal connections to transit without having to re-clear security. Perhaps due to its large size and busy nature, many reviewers describe the airport as being dirty, chaotic, inefficient, and as having long lines, limited seating and rude airport/airline staff. While there are plenty of shops and eateries throughout the different terminals, many close early in the evening. The airport offers free WiFi, and all terminals have charging areas and/or outlets for charging mobile devices. For additional comfort while you wait, economy class passengers can pay to use one of the first-class airport lounges. See Airport Lounges in the guide below for locations and rates.

Sleeping in Houston Airport

Airport seating is limited and almost all seating throughout the airport includes armrests. While the airport is generally not conducive to sleeping, some travellers reportedly find workable nooks, with Terminal D (try the chapel) getting the most mentions, followed by Terminal C. With seating so bad throughout, travellers recommend a travel mat for floor sleeping. Also strongly recommended are eyeshades, earplugs/noise-cancelling headphones and a sweater or travel blanket. Explore our guide to sleeping in Houston Airport or read some traveller airport reviews for more tips.  For uninterrupted sleep, there is an airport hotel connected to all terminals via the Subway, and numerous other hotels within a quick shuttle ride away. See locations in the  Airport Hotels section below.

Good to Know

Travellers report that although the massage chairs located throughout the airport look comfortable, security staff do not let people sleep in them.

Covid-19 Update

Due to the current Covid-19 pandemic, all services and times listed below are subject to change. Some services and facilities may remain closed or operate with reduced hours.  Airport tips and suggestions in this guide and elsewhere on the site were written before March 2020 and may no longer be valid. If you are planning to sleep in the public area of the terminal overnight, have a back-up plan! We’ve heard from a few travellers at other airports and they were not permitted to stay overnight. We’re not sure if that will apply to this airport, until a reader lets us know the current situation. We will start updating all of our guides in October 2021.  To help us with this massive update, you can add or update information or write a review and submit photos and airport tips.

For more airport information continue scrolling down to explore more in our Houston Airport Guide.

In this guide we may refer to locations as “landside” and “airside”. Landside is the public area of the terminal located in the non-secure zone, before security. Airside is the secure area of the terminal that you must reach by going through security.  For more information on Europe’s Schengen Area, click here.

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 don’t let you in and have to wait until 4:00 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: 4:00AM – 7:00PM
Terminal A South: 3:15AM – 11:00PM
Terminal B: 5:00AM – 9:05PM
Terminal C North: 4:15AM – 10:00PM
Terminal C South: 5:00AM – 7:30PM
Terminal D: 4:00AM – 1:00AM
