What Are the Different IAH Parking Options?

IAH offers five distinct parking categories, each suited to a different traveler. Here is a quick breakdown so you can match your needs to the right lot.

On-Airport Options

• Terminal Garages — Best for short stays or same-day trips. Attached to each terminal, no shuttle required. Pay $5/hour up to $25/day. Payment accepted by cash, Visa, Mastercard, Amex, Discover, Apple Pay, and Google Pay.
• ecopark (JFK Boulevard) — Best for multi-day trips on a budget. Free 24/7 shuttle runs every 10-15 minutes. Uncovered costs ~$6.47/day; covered costs ~$8.31/day.
• ecopark 2 (Will Clayton Parkway) — Same pricing and shuttle service as ecopark. A second option when the main lot fills up during peak travel.
• Valet Parking — Best for travelers who want zero hassle. Drop your car at the terminal curb. Costs $30/day, per Houston Airport System published rates.

Off-Site Options

Private off-airport lots compete hard on price. Based on current Triply rates, six verified lots near IAH range from $6.63/day to $11.25/day — all with free 24/7 shuttle service. That is up to 74% cheaper than the terminal garage daily max. Off-site is especially attractive for trips lasting three days or more, where the savings add up fast. For a full breakdown of shuttle frequencies and lot details, see our guide to IAH airport parking shuttle options and free rides.

How Much Can You Save by Booking IAH Parking in Advance?

Booking ahead is one of the easiest ways to cut the george bush intercontinental airport parking cost. The official Houston Airport System parking page offers online pre-booking discounts for ecopark and valet. Off-site lots booked in advance through platforms like Triply can run significantly below walk-up rates.

Here is a real-numbers comparison for a 7-day trip across all major IAH options (based on current published rates and Triply verified lot data, June 2026):

*PreFlight's 7-day uncovered rate drops to $3.99/day, making a full week just ~$27.93 — compared to $175 at the terminal garage. That is a saving of more than 84%. Even the most expensive off-site option (The Parking Spot at $11.25/day) saves you nearly $100 over a week. For tips on finding discount codes on top of these rates, see our Bush Airport parking coupon guide.

Which IAH Parking Lot Is Closest to Your Terminal?

Choosing the right garage saves time on arrival and departure. Here is how terminal garages map to airlines at IAH (per Houston Airport System):

• Terminal A/B Garage → Terminal A (Alaska, American, Delta, Frontier, JetBlue, Southwest, Spirit, Sun Country) and Terminal B (United, United Express — note: Terminal B ticketing is closed through late 2026; check in at Terminal C)
• Terminal C Garage → Terminal C (United, United Express)
• Terminal D/E Garage → Terminal D (international carriers: Air France, British Airways, Emirates, Lufthansa, Singapore Airlines, Turkish Airlines, and more) and Terminal E (United, United Express)

Important 2026 construction note: The Terminal B ticketing lobby is closed. All Terminal B (United) passengers must check in at Terminal C, then take the Skyway to their gate. Allow at least 15 extra minutes. This is part of United's $2.6 billion Terminal B expansion — the largest single-airline terminal project in the U.S. For a visual guide to lot locations, the George Bush Airport parking map guide shows exactly where each garage and off-site lot sits relative to each terminal.

What Is the Cheapest Way to Park at George Bush Intercontinental Airport?

The cheapest option depends on your trip length. For stays under a few hours, the terminal garage's $5/hour rate is hard to beat. For anything longer than one day, off-site lots win on price every time.

Based on our analysis of verified lot data, here are the cheapest options ranked by daily rate:

1. PreFlight Airport Parking (IAH) — $3.99/day (7-day rate, uncovered) | 5-8 min from airport | Free 24/7 shuttle
2. ecopark uncovered — ~$6.47/day | on-airport | Free shuttle every 10-15 min
3. PreFlight covered — $5.78/day (7-day) / $6.63/day (standard) | Free 24/7 shuttle
4. ecopark covered — ~$8.31/day | on-airport | Free shuttle every 10-15 min
5. Comfort Suites Houston IAH Airport — $8.95/day | 6-10 min | Hotel lot with shuttle

All off-site lots listed here include free 24/7 shuttle service to all IAH terminals. The shuttles are not a downgrade — Fine Airport Parking runs every 5-7 minutes, faster than many on-airport connections. You can also enroll in TSA PreCheck to speed through security and make the slight extra transit time from an off-site lot feel invisible.

How Much Does IAH Parking Cost for a Week?

A 7-day trip is where parking costs really diverge between options. At the terminal garage, seven days costs $175. At PreFlight's weekly uncovered rate, the same trip costs just ~$27.93. That is a difference of over $147 — enough to cover checked baggage fees or a nice dinner.

Here is a quick comparison for three common trip lengths, using on-airport ecopark (uncovered, ~$6.47/day) vs. the terminal garage ($25/day):

• 3 days: Terminal Garage = $75 | ecopark = ~$19.41 | Save ~$56
• 7 days: Terminal Garage = $175 | ecopark = ~$45.29 | Save ~$130
• 14 days: Terminal Garage = $350 | ecopark = ~$90.58 | Save ~$259

For two-week trips, using an off-site lot instead of the terminal garage can save you close to $300. Booking online through fly2houston.com locks in your rate and guarantees a spot. Online pre-booking is especially important during peak periods like summer, Thanksgiving, and the December holiday window, when lots near capacity can sell out.
