How Much Does IAH Airport Parking Cost? (2026 Rates)

IAH airport parking rates range from $3.99/day to $30/day depending on the lot type, distance from terminals, and booking method. On-airport options are convenient but pricier. Off-airport lots offer the best daily rates, especially for trips of 3 days or more.

Here is a full breakdown of verified 2026 rates, based on official Houston Airport System data and current lot pricing:

For stays of 7 days or more, PreFlight Airport Parking drops to $3.99/day for uncovered and $5.78/day for covered — the lowest verified rate near IAH. That is a saving of over 84% compared to the terminal garage daily cap, based on current Triply rates.

Which IAH Parking Lot Is Closest to Your Terminal?

The right parking lot depends on which terminal your airline uses. Each on-airport garage serves specific terminals, and the free Skyway and Subway connect all five terminals 24/7.

Terminal-by-Terminal Parking Guide

• Terminal A (Alaska, American, Delta, Frontier, JetBlue, Southwest, Spirit, Sun Country) — Use the Terminal A/B Garage. Direct walkway access.
• Terminal B (United Airlines, United Express) — Important 2026 update: The Terminal B ticketing lobby is closed through late 2026. All United passengers must check in at Terminal C, then take the Skyway to B gates. Use the Terminal A/B Garage or Terminal C Garage.
• Terminal C (United Airlines, United Express) — Use the Terminal C Garage. Direct access.
• Terminal D (International — Air France, British Airways, Emirates, Lufthansa, Singapore Airlines, Qatar Airways, and more) — Use the Terminal D/E Garage. Direct access.
• Terminal E (United Airlines, United Express) — Use the Terminal D/E Garage. The Terminal E ticketing lobby opened February 2025 with its own departures curb.

If you park off-airport, every major lot's free shuttle drops you at your specific terminal. Fine Airport Parking runs the most frequent shuttles — every 5–7 minutes, 24/7 — making it the best choice for travelers with tight connections.

Is Off-Site IAH Parking Worth It? (On-Airport vs. Off-Airport)

For most travelers staying 2 or more days, off-site parking saves significantly over on-airport options. Here is a direct comparison based on verified 2026 rates.

On-Airport vs. Off-Airport IAH Parking

• On-airport terminal garages: $25/day max — no reservation needed, closest to terminals, walk-in convenience. Best for trips under 2 days.
• On-airport ecopark: ~$6.47–$8.31/day — good value, free shuttle every 10–15 min, add 15–20 min for shuttle travel. Best for budget-conscious travelers who want an airport-managed lot.
• Off-airport lots (PreFlight, Fine, Fast Park, The Parking Spot): $3.99–$11.25/day — lowest daily rates, all include free 24/7 shuttles, 4–10 minutes from the airport. Best for trips of 3 days or more.
• Hotel parking (Comfort Suites, Hilton Garden Inn): $8.95–$9.95/day — adds hotel amenities; shuttles may not run 24/7. Good if you need a pre-flight overnight stay.
• Valet parking (on-airport): $30/day — maximum convenience, no walking or shuttles. Best for business travelers or passengers with mobility needs.

A 5-day trip in the Terminal Garage costs $125 total. The same trip at PreFlight Airport Parking (covered) costs $28.90 — a saving of over $96, or about 77%, based on current published rates.

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

Every major off-airport lot near IAH includes a free 24/7 shuttle that drops you directly at your terminal. Shuttle frequency and travel time vary by lot.

• Fine Airport Parking: Shuttle runs every 5–7 minutes — fastest frequency of any IAH off-airport lot. Travel time 5–8 minutes to terminals.
• Fast Park & Relax: Shuttle every 10–15 minutes, 24/7. Located just 4–6 minutes from the airport.
• PreFlight Airport Parking: Shuttle runs 24/7. Located 5–8 minutes from terminals.
• The Parking Spot: Shuttle every 15 minutes, 24/7. The shuttle picks you up at your car — no walking to a shuttle stop.
• ecopark and ecopark 2 (on-airport): Free shuttle every 10–15 minutes, 24/7, operated by the Houston Airport System.

Plan to add 20–30 minutes to your arrival time when using any off-site lot. That accounts for shuttle wait, ride to the terminal, and check-in. With Houston traffic on Interstate 69 or the Sam Houston Tollway potentially adding delays, check real-time traffic on Waze before you leave home. Then factor in TSA PreCheck status — PreCheck lanes move faster and can reduce your security buffer time at IAH.

Are There Park-Stay-Fly Hotel Deals Near IAH Airport?

Yes — several hotels near George Bush Intercontinental Airport offer park-stay-fly packages that bundle a hotel night with extended parking at a combined rate lower than booking separately.

• Comfort Suites Houston IAH Airport: Parking from $8.95/day with shuttle service. Hotel guests can extend parking during their trip.
• Hilton Garden Inn Houston/Bush IAH: Parking from $9.95/day, shuttle included. Good mid-range option with reliable brand amenities.

These hotel lots are 6–10 minutes from IAH terminals by shuttle. For a full breakdown of park-sleep-fly packages — including which terminal each hotel is closest to and how to book — read our IAH airport hotel parking guide. You can also browse package rates at ParkSleepFly.com.
