Planning your first trip through George Bush Intercontinental Airport (IAH)? Get expert tips for parking, terminals, security, rideshare, and more so your travel day is smooth and stress-free.

Traveling through an airport for the first time can be exciting, but also a bit overwhelming. George Bush Intercontinental Airport (IAH) in Houston, one of the busiest travel hubs in the U.S., offers plenty of services and conveniences, but first-timers especially benefit from knowing how the airport works before stepping onto its grounds. This guide will walk you through everything you need to know, from parking and check-in to dining and getting around the terminals.

Arriving & Parking at IAH

IAH offers a variety of parking options to match different travel styles and budgets. Planning ahead can save time and reduce stress before your flight.

Terminal Parking

If you want to be as close as possible to your gate, parking garages are located next to each terminal. Terminal garages usually have the fastest access to check-in and security. Rates are generally around the daily max of approximately $25. Covered parking and electric vehicle (EV) charging stations are available in these areas.

Economy / EcoPark Lots

Travelers headed out for longer trips often choose EcoPark and EcoPark2, which offer lower daily rates and free shuttle service to all terminals. These are excellent budget-friendly choices if you don’t mind a short bus ride.

Valet & Short-Term Options

Valet parking is offered at the terminal garages and adds convenience at a slightly higher price point. Additionally, if you’re just dropping off or picking up passengers, remember curbside parking is not permitted, so use the designated drop-off lanes or nearby cell phone lots where you can wait for free until your party is ready.

Know Your Terminals

IAH consists of five main terminals labeled A through E, each serving different airlines and destinations. The airport helps passengers navigate using clear signage and maps, and most terminals are connected via shuttles or walkways.

  • Terminal A: Often serves non-United domestic flights.
  • Terminal B: Currently undergoing renovations, with passengers using Terminal C check-in and skyway connections to B gates.
  • Terminal C: A busy hub for United and many domestic routes.
  • Terminals D & E: International and long-haul flights often operate here, with customs/immigration services in Terminal E.

Tip: Check your airline and flight details ahead of time so you know which terminal you’re flying from. That helps you plan parking and arrival timing.

Security & Timing

IAH can get busy, especially during holidays and peak periods. As a general rule, you should plan to arrive at least 2 hours before departure for domestic flights and 3 hours or more for international flights.

Security wait times fluctuate, so check live updates on the official IAH or Fly2Houston app/website before you go.

Pro Tip: If you’re using services like CLEAR or TSA PreCheck, you can often move through the security lines faster.

Ground Transportation Options

IAH makes it easy to reach and leave the airport without driving:

  • Rideshare & Taxis: Designated pick-up and drop-off zones are clearly marked outside each terminal.
  • Rental Cars: The airport’s rental car center offers shuttle service and easy access to major car companies.
  • Public Transit: For budget-friendly travel, an airport bus service connects downtown Houston and IAH with scheduled departures (fare around $4.50).
Eat, Shop, and Relax

IAH offers a variety of dining and shopping options inside the terminals. From quick grab-and-go cafes to local Houston-flavored restaurants and duty-free shopping for international travelers, there’s plenty to explore while you wait for your flight.

Many terminals also offer lounges and quiet spaces to relax, free Wi-Fi throughout the airport, and services such as assistive tech for accessibility. Go to our ‘Related Content’ page for more details on dining and shopping options available throughout IAH.
