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 typically cost $30-$55, and metered taxis start around $50-$70 before tip.
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.
Transport options explained honestly
| Option | Price | Time | Best for | |--------|-------|------|----------| | METRO Bus 102 | $1.25 | 70-90 min | Budget travelers, light luggage | | Rideshare (Uber/Lyft) | $30-$55 | 30-45 min | Solo travelers, small groups | | Metered taxi | $50-$70 | 30-45 min | Those who prefer no app | | Private transfer | $55-$85 | 30-45 min | Families, groups, guaranteed price | | Shared shuttle | $25-$35 | 45-75 min | Budget with comfort | | Rental car | $40-$80/day | Self-drive | Extended stays |
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. Surge pricing during rush hour or after midnight can push fares to $60-$80.
Realistic pricing expectations
Houston is a sprawling city, and your final cost depends heavily on where you are headed.
| Destination | Taxi | Private transfer | |-------------|------|------------------| | Downtown Houston | $50-$70 | $55-$75 | | The Galleria / Uptown | $45-$60 | $50-$70 | | Texas Medical Center | $50-$65 | $55-$75 | | Sugar Land | $70-$90 | $75-$95 | | Galveston | $120-$160 | $130-$170 |
Taxis charge by meter. There is no flat rate to downtown. Tips of 15-20% are customary. 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
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 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.
