The IAH airport parking daily rate is the per-day cost to leave your car at George Bush Intercontinental Airport, ranging from $6.47/day at the on-airport ecopark (uncovered) to $30/day for valet — with off-site lots starting as low as $3.99/day for multi-day bookings (verified June 2026).

What Is the Daily Parking Rate at IAH Airport in 2026?

IAH offers five distinct parking tiers, each with its own daily rate. Per official Houston Airport System published rates, the IAH airport parking daily rate spans from $6.47 (ecopark uncovered) to $30 (valet) for on-airport options in 2026. Off-site lots bring that floor even lower — down to $3.99/day on extended prepaid bookings.

Here's every IAH parking tier in one place:

How Much Does IAH Garage Parking Cost Per Day? (A/B vs C/D/E Garages)

IAH terminal garages charge $5 per hour with a $25/day maximum, per official Houston Airport System data. That rate applies to all three garage complexes. The difference between garages is which terminals they serve — not price.

Here's exactly which garage serves which terminal:

• Terminal A/B Garage: Serves Terminals A and B — Alaska Airlines, American Airlines, Delta, Southwest, JetBlue, Spirit, Frontier, Sun Country, and United Airlines
• Terminal C Garage: Serves Terminal C — United Airlines and United Express
• Terminal D/E Garage: Serves Terminals D and E — all international carriers (Air France, British Airways, Emirates, Lufthansa, Qatar, Singapore, Turkish, etc.) plus United Express

If you park in the wrong garage, you're not stuck. IAH's free Skyway people mover connects all five terminals above-ground, inside security. The free Subway train runs underground outside security. Both run 24/7. Still, parking in the right garage saves time — especially during morning rush at IAH's busiest checkpoints.

At $25/day max, the garages make sense for trips of one to two days. For anything longer, the ecopark or an off-site lot will cost you significantly less. A 3-day garage stay runs $75 total. The same trip at ecopark uncovered costs roughly $19.41 — a savings of over $55.

2026 Construction Note: The Terminal B ticketing lobby is closed through late 2026. All Terminal B passengers (United Airlines) must check in at Terminal C and take the Skyway to their gates. Allow at least 15 extra minutes if you're flying United out of Terminal B.

How Much Does IAH Ecopark Cost? (Uncovered vs Covered Daily Rates)

The IAH ecopark is the best-value on-airport option, with two rate tiers based on coverage. According to official Houston Airport System published rates, ecopark uncovered runs ~$6.47/day and ecopark covered runs ~$8.31/day (verified June 2026).

Both ecopark locations — one on John F. Kennedy Boulevard and one on Will Clayton Parkway — offer the same free 24/7 shuttle service every 10-15 minutes to all five terminals. The shuttle is the key trade-off: you're 10-15 minutes from your terminal instead of a short walk, but you're paying about a third of the garage rate.

Which ecopark tier is worth it? Houston summers are brutal. If you're leaving your car for more than a few days, the covered ecopark at ~$8.31/day protects your car from sun, rain, and hail. The $1.84/day difference adds up to just over $12 on a 7-day trip — a reasonable cost for covered parking compared to a scorched interior.

Both ecopark lots offer accessible parking with van-accessible spaces available. Payment is accepted via cash, Visa, Mastercard, Amex, Discover, Apple Pay, and Google Pay. You can also pre-book online at fly2houston.com for confirmed daily rates before you arrive.

How Much Is Valet Parking at IAH Airport?

IAH valet parking costs $30/day, making it the most expensive on-airport parking option. You drop your car at the terminal curbside, hand over your keys, and skip the shuttle entirely. It's the fastest option for anyone who values time over money.

Valet makes the most financial sense for short trips — one or two nights. At $30/day, a 3-day trip runs $90. The same trip at ecopark uncovered costs under $20. Over a full week, valet costs $210 vs roughly $45 at ecopark — a difference of $165.

Valet is also available through some off-site lots. Fine Airport Parking (IAH) offers a valet option at $9.99/day with luggage assistance and a shuttle that runs every 5-7 minutes. That's a significant savings over on-airport valet for trips longer than a day or two.

What Are the Cheapest Off-Airport Parking Options Near IAH?

Off-site lots are consistently cheaper than on-airport parking at IAH. Based on current Triply rates, the IAH airport parking daily rate at off-site lots ranges from $6.63 to $11.25/day — and prepaid weekly rates drop as low as $3.99/day. All six verified lots include free 24/7 shuttle service to all IAH terminals (verified June 2026).

For a full breakdown of the best off-site options including amenities and shuttle frequency, see our IAH off-airport parking guide with 2026 rates.

PreFlight Airport Parking (IAH) offers the lowest standard daily rate at $6.63/day for covered parking. For the fastest shuttles, Fine Airport Parking runs every 5-7 minutes — the best frequency of any off-site lot near IAH. Fast Park & Relax is covered and fully staffed 24/7, making it a strong choice for overnight or multi-day trips.

Hotel park-and-fly packages at the Comfort Suites and Hilton Garden Inn add access to hotel amenities. For more on that option, check out the IAH airport hotel parking and park-sleep-fly guide.

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

Booking online is the easiest way to lower your IAH airport parking daily rate. According to Houston Airport System, pre-booking at fly2houston.com unlocks discounted rates not available at the gate. Off-site lot rates also vary by how far in advance you book — prepaid rates are consistently lower than drive-up prices.

Here's a concrete example of the savings. PreFlight Airport Parking's 7-day prepaid rate drops to $3.99/day uncovered — compared to $5.78/day at the standard rate. Over 7 days, that's a savings of about $12.53. At the on-airport garage, the same 7-day trip at $25/day runs $175. Choosing PreFlight's weekly rate instead saves you over $147 on a one-week trip.

All six verified off-site lots offer free cancellation on pre-booked reservations. That means there's no risk in booking early. Lock in your rate now and cancel for free if your plans change.

Which IAH Parking Lot Is Closest to Your Terminal?

The closest parking to any IAH terminal is always the matching terminal garage — but not every lot is equal for every airline. Here's a terminal-by-terminal breakdown to help you choose the right parking option.

• Terminal A (Alaska, American, Delta, Southwest, JetBlue, Spirit, Frontier, Sun Country): Use the Terminal A/B Garage. Walk directly to the terminal — no shuttle needed.
• Terminal B (United Airlines — check in at Terminal C in 2026): Terminal A/B Garage is the closest on-site option. Take the Skyway from Terminal C to gates.
• Terminal C (United Airlines, United Express): Terminal C Garage is your best bet. Direct walking access.
• Terminal D — Mickey Leland International Terminal (Air France, British Airways, Emirates, Lufthansa, Qatar, Singapore, Turkish, etc.): Use the Terminal D/E Garage. Walking distance to the terminal.
• Terminal E (United Airlines, United Express): Terminal D/E Garage. The Terminal E Ticketing Lobby opened February 2025 — independent check-in is now available without going through Terminal C.

For off-site lots, all six verified lots provide shuttle service to all five terminals — not just one. The shuttle drops you at your specific terminal curb. Distance from lot to terminal curb is 4-10 minutes by shuttle, depending on the lot.

IAH Airport Parking Tips: How to Avoid Peak Rates and Long Walks

IAH has roughly 40,000 parking spaces across all facilities, per Houston Airport System data. Even so, peak travel periods — holiday weekends, spring break, and major events — can fill popular lots fast. Here's how to get the best IAH airport parking daily rate and avoid the most common headaches.

• Book at least 3-5 days ahead. Off-site lot rates rise closer to departure. Early bookings lock in the lowest prices.
• Use ecopark for trips of 2+ days. At ~$6.47/day uncovered, it's the cheapest on-airport option. The 10-15 min shuttle is a fair trade at that price.
• Choose covered parking in summer. Houston heat is extreme. Covered ecopark or an off-site covered lot like Fast Park & Relax protects your car and keeps it cooler on return.
• Skip the garage for long trips. At $25/day, garages are fine for one night. For 5+ days, even the ecopark saves over $90.
• Allow extra time for the Terminal B situation. United passengers using Terminal B must check in at Terminal C and take the Skyway. Build in at least 15 extra minutes in 2026.
• Check traffic before you leave. IAH sits 23 miles north of downtown Houston. Houston traffic can add 20-30 minutes to your drive. Use the Waze live traffic map to time your departure.
• TSA PreCheck saves time at security. Faster screening means you can cut it closer to departure. TSA PreCheck enrollment pays for itself quickly on frequent flights out of IAH.
• Use free cancellation to your advantage. All six off-site lots on Triply include free cancellation. Book early, cancel if plans change — no risk.

IAH is in the middle of two major construction programs in 2026: a $1.46 billion Terminal Redevelopment Program nearing completion and a $2.6 billion United Airlines Terminal B expansion underway. No parking lot closures are expected, but allow extra time near Terminal C and B areas during peak hours.

The iah airport parking daily rate varies widely depending on how early you book and which lot you choose. Off-site lots can run 74% cheaper than garage rates for week-long trips. The best move is to compare options before you drive to the airport — you can't change your rate once you pull up to the gate.
