IAH Airport Parking Cost Per Day: 2026 Rates & Savings Guide

Back to IAH Airport Parking Fee Guide | Complete IAH Airport Parking Guide

IAH airport parking cost per day is the daily rate you pay to store your vehicle at George Bush Intercontinental Airport — ranging from $6.63/day at off-site lots up to $25/day at on-airport terminal garages, with valet at $30/day. The on-airport ecopark sits in the middle at roughly $6.47–$8.31/day depending on covered or uncovered. Off-site lots start even lower — PreFlight Airport Parking runs as low as $3.99/day on 7-day bookings (verified June 2026). That is a spread of over $26/day between the cheapest and most expensive options, so knowing the difference before you drive saves real money.

• Terminal garages cost $5/hr with a $25/day maximum, per Houston Airport System official rates.
• EcoPark uncovered runs ~$6.47/day; EcoPark covered runs ~$8.31/day — both with free 24/7 shuttle every 10–15 minutes.
• Valet parking at IAH costs $30/day — the most expensive on-airport option.
• Off-site lots range from $6.63/day (PreFlight) to $11.25/day (The Parking Spot), all with free 24/7 shuttles.
• Booking online at fly2houston.com unlocks discounts on ecopark; off-site lots offer free cancellation when pre-booked.
• Terminal B passengers must check in at Terminal C through late 2026 due to active construction — allow extra time.

How Much Does IAH Airport Parking Cost Per Day in 2026?

IAH airport parking cost per day spans five distinct tiers, from free (cell phone lots) to $30/day valet. According to Houston Airport System's official parking rates, the terminal garages charge $5 per hour up to a $25 daily maximum. That cap makes garages reasonable for short stays but expensive for trips lasting more than a day or two.

Here is a full breakdown of every on-airport option (verified June 2026):

For multi-day trips, ecopark is the best on-airport value. A 5-day stay in the ecopark uncovered lot costs roughly $32.35 total — compared to $125 in a terminal garage. That is a savings of over $90 on a single trip, based on current Houston Airport System rates.

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

George Bush Intercontinental Airport offers five main categories of parking: terminal garages, ecopark lots, valet, off-site private lots, and hotel park-and-fly packages. Each one suits a different traveler and trip length.

On-Airport Options

• Terminal A/B Garage — Serves Terminals A and B. Covered, closest to Alaska, American, Delta, JetBlue, Southwest, Spirit, United, and United Express gates.
• Terminal C Garage — Serves Terminal C. Direct covered access for United Airlines passengers.
• Terminal D/E Garage — Serves Terminals D and E. Best for international flights on Emirates, Lufthansa, British Airways, Air France, and other carriers at the Mickey Leland International Terminal.
• EcoPark (JFK Boulevard) — Uncovered lot near the airport entrance. Free shuttle every 10–15 minutes to all terminals.
• EcoPark 2 (Will Clayton Parkway) — Covered option. Same free 24/7 shuttle. Slightly higher rate (~$8.31/day) but protects your car from Houston's heat and rain.
• Valet Parking — Drop your car at the terminal curb. Staff park it for you at $30/day.

IAH has roughly 40,000 total parking spaces across all facilities, per Houston Airport System data. That sounds like a lot — but terminal garages fill fast during holidays and summer peak season. Booking ahead is always smart.

Off-Site Private Lots

Six verified off-site lots operate near IAH, all with free 24/7 shuttles. They run 74% cheaper than valet at their best rates. For a deeper look at every nearby lot, see our guide to IAH off-airport parking options and rates for 2026.

How Much Does It Cost to Park at IAH for a Week?

A one-week trip is where the cost differences really add up. The table below shows total cost for a 7-day stay at each option, based on verified 2026 daily rates.

PreFlight's 7-day uncovered rate of $3.99/day is the lowest verified rate across all options — that is 84% cheaper than valet on a week-long trip. Even compared to EcoPark, PreFlight saves you roughly $17 over seven days. For a full look at week-long and extended stays, check our IAH long-term parking rates guide.

Where Are the Cheapest Parking Lots Near IAH Airport?

The six cheapest off-site lots near George Bush Intercontinental Airport are all located within 4–10 minutes of the terminals and include free 24/7 shuttles. Here are all six, ranked by daily rate (verified June 2026):

Fine Airport Parking runs the most frequent shuttle — every 5–7 minutes, 24/7 — making it the best option if you have an early morning flight or a late arrival. It also has 20 EV charging spaces on-site, which no other off-site lot currently offers. The two hotel lots (Comfort Suites and Hilton Garden Inn) give you the added option of a park-sleep-fly package if you have an early departure. For more on that strategy, see our IAH airport hotel parking and park-sleep-fly guide.

Is It Cheaper to Book IAH Parking Online or Pay at the Gate?

Yes — booking online is almost always cheaper at IAH. The Houston Airport System offers discounts when you pre-book ecopark through fly2houston.com. Off-site lots also lower their rates for advance online reservations, and all six verified off-site lots offer free cancellation when booked in advance.

Beyond price, pre-booking guarantees you a spot. Terminal garages and ecopark fill up during peak periods — Thanksgiving week, spring break (March), and summer (June–August). During a holiday weekend, arriving without a reservation can mean circling full lots or paying valet rates you did not budget for.

Use Triply's IAH parking search to compare live rates across on-airport and off-site lots side by side. You can filter by price, covered vs. uncovered, and shuttle frequency — then book in under two minutes.

How Do IAH Airport Shuttles Work and How Long Do They Take?

IAH shuttle service falls into two categories: on-airport people movers and off-site lot shuttles. Both are free. Understanding how each works saves you from missing your flight.

On-Airport: Skyway and Subway

The Skyway is a free automated people mover that runs above ground, connecting all five terminals inside security. The Subway is a free underground train connecting all terminals outside security. Both run 24/7. If you park in the Terminal C garage but fly from Terminal A, the Subway gets you there in minutes — no shuttle needed.

2026 note: The Terminal B ticketing lobby is closed through late 2026 due to the United Airlines $2.6 billion Terminal B expansion — the largest single-airline terminal project in U.S. history. All Terminal B passengers must check in at Terminal C, then take the Skyway to their gates. Build in an extra 15–20 minutes. No parking closures are expected in 2026.

EcoPark Shuttles

EcoPark (JFK Boulevard) and EcoPark 2 (Will Clayton Parkway) both offer free 24/7 shuttle service every 10–15 minutes to all terminals. Ride time is typically 5–10 minutes. Look for the dedicated shuttle pickup area when you arrive — signage at both lots directs you there.

Off-Site Lot Shuttles

Every major off-site lot runs 24/7 service. Fine Airport Parking has the highest frequency at every 5–7 minutes. Fast Park & Relax and PreFlight Airport Parking run every 10–15 minutes. The Parking Spot runs every 15 minutes. All shuttles serve all IAH terminals. Plan for a total transfer time (walk to shuttle, ride, terminal drop-off) of 15–25 minutes from most off-site lots.

What Is the Parking Plus Loyalty Program at IAH and Is It Worth It?

The Houston Airport System operates a Parking Plus loyalty program for frequent IAH parkers. Enrolled members earn points on paid parking stays at on-airport lots, including the terminal garages, ecopark, and ecopark 2. Points accumulate toward free parking days and other rewards.

If you fly out of IAH regularly — say, twice a month for business — the program adds up quickly. A frequent traveler parking in ecopark covered at ~$8.31/day for 24 trips per year spends roughly $200/year on parking. Even a modest reward redemption rate cuts that meaningfully. Enrollment is free through the Houston Airport System. Check the official IAH parking page for current program terms and point values, as reward structures can change seasonally.

Off-site lots have their own loyalty programs too. The Parking Spot offers its Spot Club Rewards program, which provides members with free days and discounts. If you use The Parking Spot regularly, enrolling in Spot Club before your next trip is a smart move.

IAH Parking Tips: How to Save Money and Avoid Common Mistakes

These tips come from a close analysis of all verified IAH parking options and common traveler patterns at George Bush Intercontinental Airport in 2026.

Book at Least 48–72 Hours Ahead

Off-site lots and ecopark fill during peak periods. Booking 2–3 days in advance locks in the best rates and guarantees your space. For holiday travel (Thanksgiving, Christmas, spring break), book 2–3 weeks ahead — especially for covered or close-in lots that sell out first.

Match Your Lot to Your Terminal

Flying United from Terminal B or C? The Terminal C Garage is your closest covered option. Flying international from Terminal D? Use the Terminal D/E Garage. Using the wrong garage means a longer walk or an extra leg on the Subway — not a disaster, but it adds time. Remember: the Subway runs outside security, so if you need to change terminals before clearing TSA, budget that transfer time.

Factor in the Terminal B Closure

All Terminal B passengers check in at Terminal C through late 2026. Even if you park in the Terminal A/B Garage, you will need extra time to navigate check-in at Terminal C. TSA PreCheck helps speed up security, but the extra walking distance remains. Arrive at least 2.5 hours before your flight if you are a Terminal B flyer.

Choose Covered Parking for Long Trips

Houston summers are brutal. Leaving your car in uncovered parking for 7–14 days during July or August means returning to a scorching interior. EcoPark 2's covered option at ~$8.31/day and Fast Park & Relax at $10.95/day are worth the modest premium for longer trips.

Check Traffic Before You Leave

IAH sits 23 miles north of downtown Houston. The drive can take 25 minutes or 60 minutes depending on traffic on Interstate 69 / US-59 or the Sam Houston Tollway (Beltway 8). Always check real-time traffic on Waze before you leave home. Missing your shuttle window because of a traffic jam is one of the most common — and avoidable — IAH parking mistakes.

Do Not Lose Your Ticket

Lost-ticket fees at terminal garages can be steep. Take a photo of your parking level, section, and space number the moment you park. Store your ticket in the same pocket as your boarding pass. At off-site lots, many operators use license-plate recognition — confirm your lot's system at check-in so you know what to expect on return.

Use Coupons and Promo Codes

Many off-site lots release discount codes through booking platforms. Our Bush Airport parking coupon guide tracks the best current deals across all major IAH lots — it is updated regularly and worth checking before you book.

The IAH airport parking cost per day ranges from under $4 to $30 depending on the option. Most travelers find the sweet spot in ecopark or a pre-booked off-site lot, where you save $80–$150 on a typical week-long trip versus parking in a terminal garage.
