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

The cheapest IAH parking options are EcoPark uncovered (on-airport, ~$6.47/day) and PreFlight Airport Parking (off-site, from $3.99/day on 7-day bookings). Both include free 24/7 shuttle service to all terminals.

Here's a quick breakdown of budget-friendly choices:

• EcoPark (on-airport, JFK Boulevard): ~$6.47/day uncovered, ~$8.31/day covered. Free shuttle every 10–15 minutes. Best for travelers who want on-airport security without the garage price.
• EcoPark 2 (on-airport, Will Clayton Parkway): Same rates as EcoPark. Free 24/7 shuttle to all terminals. Useful if EcoPark is full during busy travel periods.
• PreFlight Airport Parking (IAH): $6.63/day standard, drops to $3.99/day uncovered for 7-day bookings. Gated, well-lit, 24/7 monitoring, 5–8 minutes from the airport.
• Fine Airport Parking (IAH): $9.99/day with the fastest shuttle frequency of any off-site lot — every 5–7 minutes. Also offers EV charging (20 spaces) and valet.

For long-term parking, off-site lots consistently beat on-airport prices. Our IAH long-term parking rates guide breaks down weekly and extended-stay costs in detail. If you're staying near the airport the night before a flight, check the IAH park-sleep-fly hotel packages — hotel lots like Comfort Suites and Hilton Garden Inn offer parking from $8.95/day bundled with a room.

On-Site vs Off-Site IAH Parking: Which Is the Better Deal?

Off-site parking is almost always cheaper for stays longer than one day. On-site parking wins when you need the closest walk to your terminal or a short-notice same-day spot.

On-Site Parking: Pros and Cons

• Pro: Walk directly from your car to the terminal — no shuttle needed for garage parking
• Pro: Three dedicated garages serve specific terminals (A/B Garage, C Garage, D/E Garage)
• Pro: Accessible parking on the ground level of all terminal garages
• Con: Terminal garages cost $25/day — among the priciest options
• Con: Valet at $30/day is convenient but expensive for multi-day trips
• Con: EcoPark still requires a free shuttle, so you're not saving time vs off-site lots

Off-Site Parking: Pros and Cons

• Pro: Rates from $6.63/day — up to 74% cheaper than terminal garages
• Pro: All major off-site lots include free 24/7 shuttle to all terminals
• Pro: More amenities at some lots — Fine Airport Parking offers EV charging and valet
• Con: Shuttle adds 15–30 minutes to your airport arrival time
• Con: Less convenient for very short trips (under 3 hours) vs driving straight to the garage

Bottom line: For trips of 2 days or more, off-site parking saves real money. For a 7-day vacation, switching from a terminal garage ($175) to PreFlight Airport Parking ($27.93) saves over $147. That pays for a meal or two on your trip.

How Do IAH Parking Shuttles Work — and How Long Do They Take?

Every major IAH parking option includes free shuttle service. Shuttle wait times and frequency vary by lot — here's exactly what to expect at each one (verified June 2026).

• EcoPark and EcoPark 2 (on-airport): Free 24/7 shuttle to all five terminals. Runs every 10–15 minutes from designated pick-up areas.
• Fine Airport Parking (IAH): Best shuttle frequency off-site — every 5–7 minutes, 24/7. Shuttles rotate continuously between the lot and all terminals.
• PreFlight Airport Parking and Fast Park & Relax (IAH): Free 24/7 shuttle every 10–15 minutes. Both lots are 4–8 minutes from the airport.
• The Parking Spot (IAH): Free 24/7 shuttle every 15 minutes. The shuttle picks you up at your car — no walking to a central stop.
• Comfort Suites and Hilton Garden Inn (Parking): Shuttle service to and from IAH terminals. Check operating hours when you book, as hotel shuttle schedules may differ from 24/7 lots.

Once you reach the terminal, IAH's free Skyway (automated people mover, inside security) and free Subway (underground train, outside security) connect all five terminals 24/7. You don't need a separate shuttle between Terminal A, B, C, D, or E.

2026 construction note: Terminal B's ticketing lobby is closed through late 2026. United Airlines passengers flying from Terminal B must check in at Terminal C and take the Skyway to their gates. Budget an extra 15–20 minutes if you're a United traveler parking at the Terminal A/B Garage. Per the Houston Airport System redevelopment page, no parking closures are expected in 2026.

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

Booking IAH airport parking in advance — especially online — typically unlocks lower rates than paying at the gate. The Houston Airport System's official site, fly2houston.com, allows pre-booking for ecopark lots at discounted rates. Off-site lots also offer lower prices through online reservation platforms compared to walk-up rates.

Key savings strategies:

• Book at least 1 week ahead: PreFlight Airport Parking drops to $3.99/day (uncovered) or $5.78/day (covered) on 7-day pre-bookings — vs $6.63/day standard rate
• Use coupon codes: Several off-site lots offer first-time discount codes. The Bush Airport parking coupon guide lists current deals for 2026
• Compare multiple lots: Rates across IAH's six off-site lots span nearly $7/day — comparing before booking is the single fastest way to save
• Choose free cancellation: All six verified off-site lots offer free cancellation, so there's no risk in booking early
• Avoid driving in without a reservation on holidays: IAH has ~40,000 parking spaces, but popular lots fill up during Thanksgiving, Christmas, and spring break

For travelers flying on TSA PreCheck or CLEAR biometric screening, pre-booking parking ahead of time completes your pre-trip checklist — you arrive, park, clear security fast, and board stress-free.

Which IAH Parking Lot Is Closest to My Terminal?

The closest parking to your terminal depends on which airline you're flying. The three terminal garages each serve specific terminals — walk directly from your car without a shuttle.

• Terminal A/B Garage: Serves Terminals A and B. Use this for Alaska Airlines, American Airlines, Delta, Frontier, JetBlue, Southwest, Spirit, and Sun Country (Terminal A) or United Airlines domestic (Terminal B).
• Terminal C Garage: Serves Terminal C. United Airlines and United Express passengers. Note: Terminal B passengers must currently check in at Terminal C due to 2026 construction.
• Terminal D/E Garage: Serves Terminals D and E. Use for international flights on Air France, British Airways, Emirates, Lufthansa, Singapore Airlines, Qatar Airways, and other carriers in Terminal D. United passengers at Terminal E can also use this garage.

If your airline's garage is full, use the free Skyway or Subway to reach your terminal from any other garage. All five terminals are connected 24/7 — it adds time, but it works. For a full breakdown of which airlines fly from which terminal, the Bush Airport parking options guide covers terminal-by-terminal details.

Is There Covered Parking at IAH — and Is It Worth the Extra Cost?

Yes, covered parking is available at IAH both on-airport and off-site. Houston's heat and storm season make covered parking worth considering — summers regularly push past 95°F, and afternoon thunderstorms are common from May through September.

Here are the covered options and their daily rates (verified June 2026):

• EcoPark covered (on-airport): ~$8.31/day — about $1.84/day more than uncovered EcoPark
• Terminal Garages (on-airport): Fully covered, $25/day max — the most weather-protected option, but the priciest for multi-day stays
• PreFlight Airport Parking covered: $6.63/day standard, $5.78/day on 7-day bookings — best value for covered off-site parking
• Fine Airport Parking covered: $9.99/day, includes EV charging at 20 dedicated spaces
• Fast Park & Relax (IAH): $10.95/day, fully covered long-term lot, 4–6 minutes from the airport
• The Parking Spot covered: $11.25/day — highest-priced off-site option, but includes Spot Club Rewards and valet availability

For travelers parking more than 5 days during summer, covered parking pays off in comfort — you won't return to a 140°F car interior. For short trips or budget travelers, EcoPark uncovered at ~$6.47/day remains the most popular choice.
