IAH Airport Parking: What You Need to Know First

George Bush Intercontinental Airport is Houston's primary international gateway, located 23 miles north of downtown Houston. The drive takes 25-40 minutes depending on traffic — and Houston traffic can be severe, especially on Interstate 69 and Beltway 8. According to FAA aviation statistics, IAH ranks among the busiest airports in the United States, serving tens of millions of passengers annually.

The airport has five terminals: A, B, C, D, and E. Terminal A handles most domestic carriers including Alaska, American, Delta, Frontier, JetBlue, Southwest, and Spirit. Terminals B, C, and E are United Airlines hubs. Terminal D — officially the Mickey Leland International Terminal — handles international carriers like Emirates, British Airways, Lufthansa, Singapore Airlines, and 11 others. Parking garages are attached to specific terminals, so knowing which terminal you depart from saves a lot of walking.

The airport is operated by the Houston Airport System, a department of the City of Houston. You'll sometimes hear it called "Bush Airport" or "Houston Intercontinental" — both refer to the same place. The IATA code is IAH. When searching for parking, use either the full name or the code to pull up accurate options.

One critical 2026 update: the Terminal B ticketing lobby closed in January 2025 and won't reopen until late 2026. All Terminal B passengers must check in at Terminal C, then take the free Skyway people mover to their gates. Build in extra time if you're on United and departing from Terminal B.

Terminal Garages at IAH: Parking by Terminal

The terminal garages at IAH charge $5 per hour with a $25/day maximum, per official Houston Airport System published rates (verified June 2026). Each garage connects directly to its terminal, making them the most convenient option for short-term parking and drop-offs.

Here's how the garages are organized by terminal:

• Terminal A/B Garage — Serves Terminals A and B. Alaska, American, Delta, Southwest, and other domestic carriers use Terminal A. United Airlines (Terminal B) passengers check in at Terminal C in 2026 — allow extra time.
• Terminal C Garage — Serves Terminal C. United Airlines and United Express. Also where Terminal B passengers currently check in.
• Terminal D/E Garage — Serves Terminals D and E. Terminal D handles all international flights. Terminal E opened its new ticketing lobby in February 2025 and now has its own independent check-in.

The free Skyway (an automated people mover running above ground, inside security) and the Subway (a free underground train running outside security) connect all five terminals. If you park at the wrong garage, you can still reach your terminal — just budget extra time. Accessible parking is on the ground level of every terminal garage, with van-accessible spaces available. The garages accept cash, Visa, Mastercard, Amex, Discover, Apple Pay, and Google Pay.

The terminal garages don't publish specific height clearances publicly, but standard passenger vehicles clear without issue. Oversized vehicles, trucks with high profiles, or vehicles with roof racks should consider the ecopark lots, which are open-air and have no height restrictions.

IAH Ecopark: The Best Value On-Airport Parking

The ecopark lots are IAH's economy parking option and the cheapest way to park on airport property. Ecopark uncovered costs approximately $6.47/day and ecopark covered costs approximately $8.31/day, based on current Houston Airport System published rates.

There are two ecopark locations:

• Ecopark — Located on John F. Kennedy Boulevard near the airport entrance. Free 24/7 shuttle to all terminals, running every 10-15 minutes.
• Ecopark 2 — Located on Will Clayton Parkway. Also offers free 24/7 shuttle service to all terminals.

Both lots run shuttles around the clock, every day of the year. You don't need to call ahead — just pull in, grab a ticket, and board the next shuttle. The shuttle drops you at your terminal directly. On the return, the shuttle picks up at the terminal arrivals level and brings you back to your lot.

Houston summers are brutal — temperatures routinely top 95°F with high humidity. The covered ecopark option costs just $1.84/day more than uncovered. For a one-week trip, that's about $13 extra to protect your car from the heat. Many travelers find it worth it. Houston also sees occasional flooding, particularly during hurricane season (June–November), so covered parking provides an extra layer of protection.

You can pre-book ecopark online at fly2houston.com's parking page for prepaid discounted rates. Pre-booking guarantees your spot, which matters during Thanksgiving, spring break, and summer peak weeks when ecopark fills up fast.

How Much Does IAH Airport Parking Cost in 2026?

IAH parking rates vary significantly by lot type, duration, and whether you book in advance. Here's the full breakdown based on Houston Airport System published rates and verified off-site provider data (verified June 2026):

For a cost reality check: a 7-day trip in the terminal garage costs $175. The same trip at PreFlight's 7-day uncovered rate costs $27.93 — a savings of over 84%. Even ecopark uncovered at ~$6.47/day runs $45.29 for 7 days, compared to the terminal garage's $175. The math strongly favors economy or off-site options for any trip longer than two days.

Long-Term IAH Parking: Best Options for 4+ Day Trips

For trips lasting four days or more, the terminal garages become expensive fast. The best long-term IAH parking options are ecopark, PreFlight, and Fine Airport Parking — all under $10/day with free 24/7 shuttles.

Here's a budget breakdown by trip length based on verified 2026 rates:

*PreFlight standard rate applies for trips under 7 days; 7-day discounted rate kicks in at booking.

For two-week trips, the savings at PreFlight or ecopark are dramatic. Travelers heading out for 14 days can save over $260 by choosing PreFlight over a terminal garage. Long-term travelers should always pre-book — both ecopark and off-site lots can fill up during peak holiday periods.

Shuttle logistics for long-term parking are straightforward. Ecopark shuttles run every 10-15 minutes, 24/7. Fine Airport Parking's shuttle is the most frequent of any off-site provider at every 5-7 minutes. Fast Park & Relax and PreFlight run every 10-15 minutes. The Parking Spot runs every 15 minutes. All shuttles operate 24 hours a day, 365 days a year.

Hotel Park-and-Fly Packages Near IAH

Hotel park-and-fly packages combine one or more nights at an airport hotel with days of parking — useful for early-morning flights or late arrivals. Several hotels near George Bush Intercontinental offer these packages, all with shuttle service to IAH terminals.

Park-and-fly packages typically work like this: you stay the night before your flight, leave your car in the hotel lot during your trip, and use the hotel's shuttle to reach the terminal. On return, the hotel shuttle picks you up and drives you back to your car. The hotel parking rate covers your entire stay — not just the night you slept there.

For flights departing before 6 AM or arriving after 11 PM, confirm shuttle hours with the hotel directly. Not all hotel shuttles run 24/7. The on-airport ecopark shuttles do run 24/7, which gives them an edge for very early or very late flights.

For a broader list of park-sleep-fly options near IAH, Park Sleep Fly's IAH directory catalogs current hotel-parking bundles with pricing. Parking Access also lists park-and-fly hotels near IAH with direct booking links.

Valet Parking and Short-Term Options at IAH

IAH valet parking costs $30/day, per Houston Airport System published rates (verified June 2026). Valet is available at select terminal locations. It's the most convenient on-airport option — drive up, hand over your keys, and walk straight to check-in.

Valet is worth considering if:

• You're in a rush and can't afford time to find a parking spot
• You have heavy luggage or mobility limitations
• You're parking for just one or two days and convenience outweighs cost
• Your flight is very early or very late

For short-term parking and visitor drop-offs, the terminal garages charge $5 per hour. If you're picking someone up and waiting less than 30 minutes, use the free cell phone lots. There are two: one at 17010 John F. Kennedy Boulevard (accessible from Sam Houston Tollway via JFK Blvd north) and a second at 4500 Will Clayton Parkway. Both are free. Wait there until your passenger texts you they've grabbed their bags, then pull up to arrivals. This avoids both parking fees and the circling-the-airport game.

The Parking Spot and Fine Airport Parking also offer valet service as an off-site option at their lots — at lower daily rates than the on-airport valet. The Parking Spot's valet is included with their premium covered pricing. Fine Airport Parking offers valet as an add-on service.

Off-Site Parking Near IAH: Best Lots Compared

Off-site parking near George Bush Intercontinental starts at $6.63/day and tops out at $11.25/day across six verified providers, based on current Triply rates. Every major off-site lot includes a free 24/7 shuttle to IAH terminals — and most are within 4-10 minutes of the airport by road.

Fine Airport Parking runs the most frequent shuttle of any off-site provider — every 5-7 minutes, 24/7. The lot also has 20 EV charging spaces, luggage assistance, and valet service. It's the best all-around off-site option for most travelers. Fast Park & Relax is the closest to the airport at just 4-6 minutes and offers fully covered parking — a strong pick for Houston's summer heat and storm season.

The Parking Spot at IAH is the largest off-site brand at the airport and offers a rewards program (Spot Club) that benefits frequent fliers. Uncovered spaces start at $8.75/day. The shuttle runs every 15 minutes and picks up at your car — you don't haul your bags to a bus stop. Before you drive to any of these lots, check real-time traffic on Waze — IAH access roads off Beltway 8 and JFK Boulevard can back up badly during rush hour.

IAH Parking Tips, Maps, and Practical Info

A few practical details that save time and money at IAH airport parking — most travelers skip these and end up paying more or waiting longer than necessary.

EV Charging at IAH

IAH has EV charging stations in the airport parking facilities. The official EV charging page has current station locations. Off-site, Fine Airport Parking offers 20 EV charging spaces — the most of any off-site lot near IAH. If you drive an EV, Fine Airport Parking is the most reliable off-site choice.

What About the 2026 Construction?

IAH is mid-way through a $1.46 billion Terminal Redevelopment Program, with a separate $2.6 billion United Airlines Terminal B expansion also underway. No parking closures are expected in 2026 — all lots remain open. The main travel impact is the Terminal B ticketing lobby closure: Terminal B passengers check in at Terminal C through late 2026. Arrive 15-20 minutes earlier than usual if you're on a United flight. More details at the official IAH redevelopment page.

Parking Maps and Real-Time Availability

Parking maps for each terminal garage and ecopark are available on the IAH terminal parking page. Real-time availability status is also posted there. During peak holiday travel, check availability the morning of your departure — ecopark fills up fastest.

Security and Getting to Your Gate

From any IAH parking area, you'll enter one of the terminal security checkpoints. Review TSA security screening guidelines before you fly — especially for international travel through Terminal D. Travelers with TSA PreCheck can use dedicated lanes and typically clear security in under 10 minutes. International travelers should look into the Global Entry program — it covers both TSA PreCheck and expedited customs on return, which matters a lot at a busy international hub like Terminal D.

Oversized Vehicles and Special Situations

Oversized vehicles, trucks with raised suspensions, or vehicles with roof cargo should use ecopark or off-site lots. The open-air design has no height restrictions. If you're traveling with a large group, Fine Airport Parking and The Parking Spot both offer luggage assistance. Lost items in a parking facility should be reported directly to parking operations via the contact info on fly2houston.com.

On-Airport vs. Off-Site: Quick Comparison

• Terminal Garages: Walk to your terminal in minutes. Best for short trips (1-2 days). Costs $25/day max.
• Ecopark: Cheapest on-airport option at ~$6.47-$8.31/day. Shuttle every 10-15 min. Best for 3-14 day trips.
• Off-site lots: Starting at $3.99/day with free 24/7 shuttles. Best savings for long trips. Adds 5-15 min to airport arrival time.
• Valet (on-airport): $30/day. Zero hassle. Best for travelers who prioritize time over cost.
• Hotel park-and-fly: Combines overnight stay with parking. Useful for very early or very late flights.
