How Much Does IAH Airport Parking Cost in 2026?

George Bush Intercontinental Airport offers parking at five distinct price points, per official Houston Airport System published rates. The cheapest on-airport option is ecopark uncovered at ~$6.47/day. The terminal garages cost $5/hr with a $25/day cap — fine for a few hours, expensive for multi-day trips. Here is the full breakdown of IAH airport parking charges (verified June 2026):

These rates apply to standard daily parking. Hourly garage charges accumulate quickly — five hours in a terminal garage already hits the $25/day maximum. If you plan to stay longer than five hours, the daily cap kicks in automatically, so the garage becomes cost-equivalent to one full day regardless of your actual departure time.

What Are the Different Parking Options at George Bush Intercontinental Airport?

IAH has roughly 40,000 parking spaces across on-airport and nearby off-site facilities, according to Houston Airport System data. Each option serves a different traveler need. Here is how each one works:

Terminal Garages

Three garages serve IAH's five terminals. The Terminal A/B Garage is closest to Terminals A and B. The Terminal C Garage serves Terminal C. The Terminal D/E Garage covers Terminals D and E. All garages are a short walk to their respective terminals. Use the free Skyway (inside security, above ground) or the free Subway train (outside security, underground) to reach a different terminal from your garage.

Ecopark and Ecopark 2

Ecopark sits on John F. Kennedy Boulevard near the airport entrance. It offers uncovered self-parking at ~$6.47/day. Ecopark 2 is located on Will Clayton Parkway and provides covered parking at ~$8.31/day. Both lots run free 24/7 shuttle service to all terminals every 10-15 minutes. The main difference: ecopark 2 gives your car a roof over it, which matters during Houston's intense summer heat and sudden rainstorms. For a deeper look at ecopark 2, see our guide to IAH EcoPark2 covered parking rates and features.

Valet Parking

Valet is available at $30/day. You drive directly to the terminal, hand over your keys, and the team parks your car. Retrieval typically takes a few minutes after you call ahead. It is the most convenient option but costs nearly five times more than ecopark uncovered over a 7-day trip.

Off-Site Private Lots

Six verified off-site lots operate near IAH with rates from $6.63/day to $11.25/day. All include free 24/7 shuttle service. The two hotel-based lots (Comfort Suites and Hilton Garden Inn) add the perk of hotel amenities if you are combining a park-sleep-fly trip. For a full breakdown of hotel parking packages, see our IAH airport hotel parking guide.

How Much Is Long-Term Parking at IAH Per Day and Per Week?

Long-term parking costs at IAH depend heavily on which lot you choose and whether you book in advance. Based on current published rates, here is what a 7-day stay costs across the main options:

• Terminal Garage: $25/day × 7 days = $175/week
• Ecopark uncovered: ~$6.47/day × 7 days = ~$45.29/week
• Ecopark 2 covered: ~$8.31/day × 7 days = ~$58.17/week
• Valet: $30/day × 7 days = $210/week
• PreFlight Airport Parking (7-day prepaid, uncovered): $3.99/day = $27.93/week — cheapest available
• PreFlight Airport Parking (7-day prepaid, covered): $5.78/day = $40.46/week
• Fine Airport Parking: $9.99/day = $69.93/week
• The Parking Spot (covered): $11.25/day = $78.75/week

PreFlight's 7-day prepaid rate of $3.99/day uncovered is the lowest we found across all verified IAH options. That is 84% cheaper than the terminal garage over a week. For frequent travelers, that difference adds up fast. For more detail on week-long pricing, our IAH long-term parking rates guide covers extended-stay strategies in full.

What Is the Cheapest Way to Park at IAH Airport?

The cheapest IAH airport parking charges you will find are at PreFlight Airport Parking on a 7-day prepaid booking: $3.99/day uncovered. For stays under a week, ecopark uncovered at ~$6.47/day is the most affordable on-airport option. Off-site lots often beat on-airport prices even without a weekly deal. Here are the top money-saving moves:

1. Book in advance online. Pre-booking at fly2houston.com or through a comparison tool like Triply locks in the lowest rates. Walk-up rates are typically higher.
2. Use a 7-day prepaid rate. PreFlight's $3.99/day uncovered rate is only available on multi-day advance bookings.
3. Choose ecopark over the garage for stays over 5 hours. The garage hits its $25/day cap quickly. Ecopark at ~$6.47/day is far cheaper for anything longer than a quick errand.
4. Check for coupons. Some off-site lots offer promo codes. Our Bush Airport parking coupon guide lists current deals.
5. Compare off-site shuttle lots. Fine Airport Parking at $9.99/day runs shuttles every 5-7 minutes — the most frequent off-site service at IAH.

Houston traffic on I-69 and the Sam Houston Tollway (Beltway 8) can be unpredictable. Before you drive, check real-time traffic on Waze so you arrive with enough buffer time before your flight.

How Do Off-Site IAH Parking Lots Compare to On-Site Garage Parking?

Off-site lots generally cost 55-84% less per day than the terminal garages, based on our analysis of current verified rates. The trade-off is a short shuttle ride instead of a direct walk. Here is a direct comparison of key factors:

• Cost (7-day trip): Terminal Garage $175 vs. PreFlight off-site $27.93 — off-site saves $147
• Distance to terminal: Garages are a direct walk. Off-site lots are 4-8 minutes by shuttle.
• Shuttle frequency: Fine Airport Parking runs every 5-7 min. The Parking Spot runs every 15 min. All operate 24/7.
• Covered options: Both have them — ecopark 2 on-airport (~$8.31/day) and Fast Park & Relax off-site ($10.95/day).
• EV charging: On-airport at ecopark, ecopark 2, Terminal A/B Garage Level 4, and Terminal CDE Garage Level 4 (via Blink). Fine Airport Parking off-site also has 20 EV spaces.
• Cancellation: All six verified off-site lots offer free cancellation. On-airport pre-bookings vary — check fly2houston.com.
• Security: All listed off-site lots are gated with 24/7 cameras and lighting. On-airport garages are staffed and monitored by the Houston Airport System.

For short trips under three hours, the terminal garage is the most convenient. For anything longer — especially multi-day trips — off-site lots or ecopark deliver significantly lower IAH airport parking charges without a meaningful trade-off in experience.

How Do You Reserve IAH Airport Parking in Advance?

Reserving in advance is the single most reliable way to secure a lower rate and guarantee a space. Online pre-booking at fly2houston.com covers on-airport lots including ecopark, ecopark 2, and the terminal garages. For off-site lots, book directly through the lot's website or compare options via Triply.

1. Go to fly2houston.com/iah/parking or Triply's IAH parking search.
2. Enter your arrival and departure dates.
3. Select your preferred lot type — garage, ecopark, or off-site.
4. Complete payment online. Accepted methods include Visa, Mastercard, Amex, Discover, Apple Pay, and Google Pay.
5. Save your confirmation email or QR code for lot entry and exit.

IAH's total capacity is approximately 40,000 spaces, but popular lots can fill up during peak travel periods like Thanksgiving, Christmas, and spring break. Booking 1-2 weeks ahead during busy seasons is a smart move.

What Amenities and Services Come With IAH Parking?

IAH parking facilities offer more than just a space for your car. According to Houston Airport System data, accessible parking is available on the ground level of all terminal garages and in all ecopark lots, including van-accessible spaces. EV drivers can charge at ecopark, ecopark 2, Terminal A/B Garage Level 4, and Terminal CDE Garage Level 4 — all powered by Blink charging equipment.

Off-site lots add their own perks. Fine Airport Parking includes 20 EV charging spaces, luggage assistance, and ADA-accessible facilities. The Parking Spot includes free water bottles, Spot Club rewards, and covered options. Fast Park & Relax is fully covered with 24/7 staffing and luggage help. If you have TSA PreCheck, factor in that faster security lanes mean you can cut your airport arrival buffer — TSA PreCheck enrollment pays for itself quickly for frequent flyers.

2026 Construction: What IAH Parkers Need to Know

IAH is in the middle of a $1.46 billion Terminal Redevelopment Program, with a separate $2.6 billion United Airlines Terminal B expansion also underway. The most important impact for parkers right now: Terminal B's ticketing lobby is closed through late 2026. All Terminal B passengers must check in at Terminal C and take the free Skyway to their gates. Allow at least 15 extra minutes if you are flying United out of Terminal B.

No parking closures are expected in 2026. The new Terminal D-West Pier (opened October 2024) added six wide-body gates and 16 dining and shopping options. Terminal E's new ticketing lobby opened in February 2025 with its own departures curb. These expansions mean more passengers — and more competition for parking spaces during peak periods. Pre-booking is especially important this year. For short-term parking near the updated Terminal E, see our guide on IAH airport short-term parking rates for 2026.
