Quick answer
IAH sits about 37 km (23 miles) northwest of downtown Houston. The cheapest way in is the METRO bus 102 for $1.25, which takes roughly 70-90 minutes depending on traffic. A private transfer runs $55-$85 and gets you there in 30-45 minutes. Rideshares are priced by the app, and taxis run on the city's regulated IAH zone tariff - you pay the lesser of your zone's flat rate or the meter, and the rate card is posted inside the cab.
Houston traffic can be brutal, especially during rush hours (7-9 AM, 4-7 PM). Plan accordingly.

What actually happens after landing
IAH has five terminals (A, B, C, D, E) connected by the Skyway automated train. International flights arrive at Terminal D or E. After clearing customs and immigration, you will walk through a long corridor before reaching the arrivals hall.
Baggage claim areas are clearly signed. Reclaim can take 20-40 minutes for international flights. Once you have your bags, follow signs to ground transportation on the lower level of each terminal.
The airport is large. If you are connecting between terminals, allow at least 15-20 minutes on the Skyway.

The METRO bus 102 runs from Terminal C to downtown. You need to take the Skyway to Terminal C first if you land elsewhere. Service runs roughly every 30 minutes during peak hours but drops off significantly after 9 PM.
Rideshare pickup is on the lower level of each terminal at designated spots. Neither Uber nor Lyft publishes a fare table, and surge pricing during rush hour or after midnight lifts the price well above the daytime norm - the app quotes you before you confirm.

Houston regulates IAH taxi fares by zone. The city publishes a flat rate for each zone - $46.13 for the nearest zone up to $141.71 for the farthest on a daytime trip, each $1.00 more at night (City of Houston, 2026 rates) - and the ordinance requires the driver to charge the lesser of the zone flat rate or the actual meter (Chapter 46, Sec. 46-31). The meter itself is $3.72 for the first 1/11 mile by day ($4.72 at night) plus $2.97 per additional mile, with waiting time at $24.00 an hour.
You do not have to guess which zone you are in: every Houston cab is required to carry a zone rate card and a zone map, one posted on the dashboard and one on the back of the front seat, so you can read the price for your destination before you set off. Ask the starter or the driver to point to your zone. The city raised these rates in 2026 and revises them periodically, so treat the card in the cab as the authority.
A $2.75 departure fee applies to trips leaving the airport, and a $1.00 surcharge is added between 8 PM and 6 AM. Seniors get 10% off. Tips of 15-20% are customary on top. Private transfers lock in the price at booking, which removes the traffic gamble.
Late night arrivals
IAH handles flights around the clock, but ground transport thins out after midnight. The METRO bus 102 stops running around 11 PM on weekdays and earlier on weekends.
Taxis queue at the lower level 24/7, though lines can be short after 1 AM. Rideshares are available but expect surge pricing of 1.5-2.5x between midnight and 5 AM. Wait times for a ride can stretch to 15-20 minutes.
A pre-booked transfer is the most reliable late-night option. The driver waits for you regardless of delays, and the price does not change.
Families and luggage
IAH has good facilities for families. Nursing rooms are available in Terminals A, B, and E. Restrooms with changing tables are in every terminal.
The bus is not practical with strollers and multiple suitcases. Taxis from the queue are standard sedans and fit two large bags at most. If you are traveling with car seats, a stroller, and more than two checked bags, a private transfer with a minivan or SUV is the sensible choice.
Free luggage carts are available near baggage carousels.
Where you meet the driver
Taxis: Lower level (arrivals) of each terminal, follow the yellow taxi signs.
Rideshares: Lower level, designated rideshare pickup zones marked with signs. Check your app for the exact spot.
Private transfers: Most drivers meet you in the arrivals hall holding a name sign. Some wait at the curb on the lower level. Your booking confirmation will specify the exact meeting point.
METRO Bus 102: Terminal C, lower level, bus stop area.
Decision helper
Take the bus if you are traveling light, have time, and want to save money.
Take a rideshare if you are alone or with one other person, traveling during normal hours, and comfortable with variable pricing.
Take a taxi if you prefer to just get in a car without an app and do not mind paying a bit more.
Book a private transfer if you are arriving late, traveling with family, have lots of luggage, or simply want a fixed price and someone waiting for you with your name.
Frequently Asked Questions
How far is IAH from downtown Houston?
George Bush Intercontinental Airport is 37 km (23 miles) north of downtown Houston. The drive takes 30-45 minutes in normal traffic.
Is there a train from IAH to Houston city center?
No. Houston does not have a rail link to IAH. The METRO bus 102 is the only public transit option, running to downtown for $1.25.
How much does a taxi cost from IAH to downtown?
There is a flat rate - this is the thing most guides get wrong about Houston. The city divides the area around IAH into zones and publishes a flat fare for each one, and Chapter 46 of the Houston Code requires the driver to charge whichever is lower, the zone flat rate or the meter. Daytime zone rates run from $46.13 for the nearest zone to $141.71 for the farthest, each $1.00 more at night (City of Houston, 2026). Every cab must post the zone rate card and a zone map on the dashboard and the rear seat back, so read your zone's price off the card before you set off. Add a $2.75 departure fee, a $1.00 surcharge between 8 PM and 6 AM, and a 15-20% tip.
Can I get an Uber or Lyft from IAH?
Yes. Rideshare pickup is on the lower level of each terminal at designated zones. Neither app publishes a fare table, so check the quote when you land - it rises with rush hour, late-night demand and bad weather.
Does the METRO bus 102 run at night?
No. The last bus leaves around 11 PM on weekdays and earlier on weekends. For late arrivals, taxis, rideshares, or pre-booked transfers are your options.
How long does it take to get through customs at IAH?
International arrivals at Terminal D or E typically take 30-60 minutes through immigration and customs, depending on time of day and flight volume.
Is there a shuttle service from IAH?
Yes, shared shuttle services operate from IAH. Fares are set by the individual operators rather than by the airport or the city, so get a quote from the operator before booking. Journey times run 45-75 minutes because of the multiple stops.
Which terminal do international flights use at IAH?
Most international flights arrive at Terminal D (the Mickey Leland International Terminal) or Terminal E. Some international carriers use Terminal C.
Can I rent a car at IAH?
Yes. The Rental Car Center is connected to the terminals by a free shuttle bus. Major companies are on site. Rates move a great deal with season and demand, so compare quotes for your dates.
Is it safe to take public transport from IAH?
The METRO bus 102 is generally safe during daytime hours. The route runs through standard urban areas. At night, a taxi or private transfer is a more comfortable choice.
Houston is a car-dependent city, and IAH reflects that. Public transit exists but is limited. If you value predictability, especially arriving late or with family, a pre-booked transfer removes the guesswork. Whatever you choose, avoid rush hour if you can.
