Whether you’re flying out of George Bush Intercontinental Airport (IAH) or arriving in the Bayou City, a compact checklist of seven must‑have items can keep your trip smooth and stress‑free. Below is an answer‑first summary followed by a concise breakdown of each essential, plus practical tips for using them at the airport and on the road.
All passengers 18 years and older must present a government‑issued photo ID at the TSA checkpoint. A U.S. driver’s license, state ID, or a valid passport works. If you’re traveling internationally, ensure your passport is not within six months of its expiration date. IAH’s five terminals (A‑E) each have dedicated ID verification lanes, so having the correct document speeds up the process.
Most carriers now offer mobile boarding passes, but it’s wise to have a backup printed copy or a screenshot saved offline. The Fly2Houston website reminds travelers that many airlines at IAH also have self‑service kiosks where you can re‑print a pass if needed. Having your confirmation code handy helps when checking baggage or changing seats.
If you’ve purchased a policy, keep the policy number and emergency contact information in your carry‑on. This can be critical for delayed flights, lost luggage, or medical emergencies while you’re navigating the airport’s sprawling concourses. Many insurers allow you to store documents in a mobile app, but a printed copy provides an extra layer of reliability.
IAH offers numerous charging stations throughout the terminals, especially near gate seating areas. However, a fully charged portable power bank (10,000 mAh or higher) ensures you stay connected while waiting for boarding calls, navigating ride‑share pickups, or using the airport’s free Wi‑Fi. Bring a cable compatible with your device and the airport’s USB‑A ports.
Staying hydrated is key, especially in Houston’s warm climate. IAH provides water‑bottle filling stations near the main concourse restrooms and in the food courts. Bring an empty reusable bottle through security and fill it after the checkpoint. This reduces waste and keeps you refreshed during long layovers.
While IAH hosts a variety of dining options—from fast‑casual to sit‑down restaurants—having a small stash of granola bars, nuts, or fruit can save time and money, particularly on early‑morning flights. Pack items that comply with TSA’s 3‑1‑1 liquids rule, and store them in a clear, resealable bag for easy inspection.
A compact kit with adhesive bandages, antiseptic wipes, pain relievers, motion‑sickness tablets, and any prescription medication you need can be a lifesaver if you experience minor injuries or unexpected aches. Keep the kit in an accessible pocket of your carry‑on so you can reach it quickly after landing or during a layover.
IAH sits roughly 15 miles north of downtown Houston, serving as the region’s primary international gateway. Whether you prefer the speed of a rideshare, the cost‑effectiveness of public transit, or the convenience of a hotel shuttle, the airport offers multiple transportation modes to fit any schedule.
The IAH Rental Car Center is located adjacent to the airport, accessible via a short complimentary shuttle ride from each terminal. Major companies (Enterprise, Hertz, Avis, National, and others) operate on‑site, allowing you to pick up a vehicle minutes after you claim your luggage. If you’re heading toward the Energy Corridor or The Woodlands, taking Interstate 45 (I‑45) south will connect you to the downtown loop (I‑610) and then to I‑10 or US‑290.
Uber, Lyft, and traditional taxi services have designated pickup zones on the arrivals level of each terminal. The average travel time to downtown Houston is about 30‑45 minutes, depending on traffic on I‑45, I‑610, or the Hardy Toll Road. Fares are metered and can fluctuate; always confirm the estimated cost in the app before confirming the ride.
METRO’s Route 102 provides direct bus service between IAH and the Downtown Transit Center, with a travel time of roughly 45‑60 minutes. Buses run every 30‑60 minutes, and the fare is a standard METRO base rate (exact change or a Go Card is accepted). From the Downtown Transit Center you can connect to the METRORail Red Line, which reaches the Museum District, the Texas Medical Center, and the Convention District.
Many hotels in the Greenspoint area, the Energy Corridor, and downtown offer complimentary shuttle service to and from IAH. Shared‑van services such as SuperShuttle also operate, providing curb‑to‑curb transport. Shuttle schedules typically align with flight arrival times; it’s best to reserve a seat in advance through the hotel’s website or a shuttle provider.

If you have a layover or are visiting Houston for the first time, several notable sites are within a short drive of IAH. The Johnson Space Center, home of NASA’s astronaut training, lies about 20 minutes south on I‑45. The Houston Museum District, encompassing 19 museums, is reachable via I‑610 eastbound and offers cultural exhibits ranging from fine arts to natural science. For shopping, the Galleria—Texas’s largest mall—sits just west of downtown on Westheimer Road, accessible via I‑610. Sports fans can catch a game at Minute Maid Park or the Toyota Center, both located in the downtown corridor, reachable by I‑45 or I‑10.
METRO Route 102 is the most cost‑effective choice, connecting the airport to the Downtown Transit Center in about 45‑60 minutes. From there you can transfer to the METRORail Red Line for further travel within the city. Buses run frequently, and the fare is lower than rideshare or taxi options.
Currently, IAH does not have a dedicated rail line. The closest rail service is the METRORail Red Line,
