What Are the Onsite Parking Options at IAH Airport?

George Bush Intercontinental Airport offers four distinct types of onsite parking. Each serves a different traveler need and budget, all managed by the Houston Airport System (verified June 2026).

• Terminal Garages — Five garages, each directly connected to its terminal. Rates are $5/hour with a $25/day maximum. The A/B Garage serves Terminals A and B, the C Garage serves Terminal C, and the D/E Garage covers Terminals D and E.
• Ecopark — Located at John F. Kennedy Boulevard near the airport entrance. Uncovered daily rate is approximately $6.47/day. A free shuttle runs 24/7, every 10-15 minutes, to all five terminals.
• Ecopark 2 — Located at Will Clayton Parkway. Covered spaces available at approximately $8.31/day. Also served by a free 24/7 shuttle.
• Valet Parking — Available at select terminals for $30/day. You drop your car at the curb and skip the walk entirely.

All onsite lots accept cash, Visa, Mastercard, Amex, Discover, Apple Pay, and Google Pay. You can also pre-book online at fly2houston.com to secure lower rates. The terminal garages are the most convenient option when time matters. The ecopark lots are the best deal for trips of two days or more.

How Much Does IAH Airport Onsite Parking Cost?

According to official IAH parking rate data published by the Houston Airport System, onsite rates in 2026 break down as follows:

For short trips under four hours, a terminal garage is hard to beat — you pay $5/hour and skip the shuttle entirely. For trips of two days or longer, the ecopark uncovered lot saves you up to 74% compared to the terminal garage daily maximum. That's a meaningful difference on a one-week trip: roughly $45 at ecopark vs. $175 at the garage. For travelers concerned about Houston's heat and rain, the ecopark covered option at ~$8.31/day is a smart middle ground.

Seasonal demand can push prices higher during Thanksgiving, spring break, and the winter holidays. Booking in advance through fly2houston.com locks in current rates before surge pricing kicks in. For a full breakdown of what different trip lengths cost at IAH, the IAH long-term parking rates guide walks through weekly and extended-stay totals in detail.

Which IAH Parking Lot Is Closest to My Terminal?

Each terminal garage at IAH is physically attached to its terminal via covered walkways — no shuttle needed. Here's the breakdown by terminal (per Houston Airport System):

• Terminal A/B Garage → Terminals A and B (Alaska, American, Delta, Frontier, JetBlue, Southwest, Spirit, Sun Country, United)
• Terminal C Garage → Terminal C (United, United Express). Note: Terminal B passengers must check in at Terminal C during the current $2.6B expansion — expect extra transit time.
• Terminal D/E Garage → Terminals D and E (international carriers + United). Terminal D is the Mickey Leland International Terminal, serving Air France, British Airways, Emirates, Lufthansa, Qatar Airways, Singapore Airlines, and more.

If you park at the wrong garage, don't stress. The Skyway — IAH's free automated people mover — connects all terminals above ground, inside security, 24/7. The Subway is the underground equivalent, running outside security. Both are free. Just factor in an extra 5-10 minutes to cross terminals. For Terminal D specifically, the Terminal D parking guide covers the D/E Garage in much more detail, including walking distances and accessibility options.

Accessible parking is available on the ground level of all terminal garages and in both ecopark lots. Van-accessible spaces are provided at each location. If you use a wheelchair, mobility aid, or travel with medical equipment, ground-level garage parking puts you steps from the elevators and terminal entrances.

How Does IAH Valet Parking Work — and Is It Worth It?

IAH valet parking costs $30/day and lets you pull up to the terminal curb, hand over your keys, and walk straight to check-in. No hunting for a space, no shuttle wait.

The process is straightforward:

1. Drive to the valet drop-off area at your departure terminal.
2. An attendant takes your keys and gives you a claim ticket.
3. Your car is parked in a secured onsite area.
4. On return, present your ticket at the valet stand and your car is brought to you.

Valet is worth it for short business trips where your time is worth more than the cost difference. At $30/day versus $25/day for the terminal garage, you're paying just $5 more per day for curbside service. For a two-day trip, that's $10 total. For longer trips, the cost stacks up faster — a week of valet runs $210, compared to $175 at the terminal garage daily cap.

How Do You Reserve IAH Onsite Parking in Advance?

Booking IAH airport onsite parking in advance is the single easiest way to save money and guarantee a spot, especially during busy travel periods.

Here's how to do it:

1. Visit fly2houston.com and select your parking type (terminal garage, ecopark, or valet).
2. Enter your travel dates and choose your preferred lot.
3. Pay online to lock in your pre-book rate — typically lower than the drive-up price.
4. On arrival, follow signs to your reserved lot. A QR code or confirmation number gets you in.

Pre-booking also helps during peak periods like holidays and spring break, when terminal garages can fill up. The Houston Airport System recommends arriving with at least 2.5 hours before domestic flights and 3 hours before international flights. If you're flying from Terminal D to an international destination, make sure to review TSA security screening guidelines — international security lines can be longer than domestic ones, especially when the new International Central Processor checkpoint is at full capacity. If you have TSA PreCheck, use the dedicated lane to save another 15-20 minutes.

Is There EV Charging Available at IAH Airport Parking?

Yes — IAH offers EV charging stations within its onsite parking facilities. According to the Houston Airport System's EV charging page, charging is available in the airport's parking areas (verified June 2026).

If you drive an electric vehicle, here's what to know:

• EV charging is available within the terminal garage parking facilities.
• Charger availability can vary — plan to arrive with enough charge to return home in case all stations are occupied.
• Off-site, Fine Airport Parking offers 20 dedicated EV charging spaces in its lot, which can be a reliable alternative if onsite stations are full.

Houston's summer heat can accelerate battery drain. If you're parking for multiple days, topping off before you leave — and confirming charger availability — saves a stressful moment on return. The IAH covered parking guide also covers which sheltered options protect your EV from direct sun exposure during long stays.

Onsite vs. Offsite IAH Parking: Which Should You Choose?

The right choice depends on your trip length, budget, and how much walking you want to do. Here's a direct comparison based on current rates and verified lot data.

IAH Onsite Parking

• Pro: Terminal garages are steps from check-in — no shuttle needed
• Pro: Ecopark lots offer competitive daily rates (~$6.47/day uncovered)
• Pro: Valet option available for maximum convenience
• Pro: Managed directly by Houston Airport System — consistent security standards
• Con: Terminal garage daily max of $25 adds up quickly on long trips
• Con: Garages can fill during peak travel periods

IAH Offsite Parking

• Pro: Rates as low as $3.99/day at PreFlight Airport Parking on weekly bookings
• Pro: Covered and uncovered options available from multiple providers
• Pro: Fine Airport Parking shuttle runs every 5-7 minutes — one of the fastest in Houston
• Con: Shuttle adds 10-20 minutes to your airport arrival process
• Con: Quality varies by provider — read reviews before booking

For trips under two days, the terminal garage at $25/day is hard to beat for convenience. For trips of five days or more, offsite lots can save you $100 or more over a week compared to onsite garage parking. For a full comparison of offsite options with shuttle details and lot reviews, see the IAH off-airport parking guide.

Quick rule of thumb: 1-2 days? Use a terminal garage. 3+ days? Ecopark or offsite saves real money. 5+ days? Offsite lots like PreFlight at $3.99/day (weekly rate) are the clear winner.

Find the Best IAH Airport Onsite Parking Rate for Your Trip

IAH airport onsite parking gives you five garages, two economy ecopark lots, and valet service — all operated by the Houston Airport System with rates from ~$6.47/day to $30/day. Terminal garages sit steps from check-in at a $25/day cap. Ecopark lots cut that cost significantly for longer stays.

Before you travel, double-check the 2026 construction situation: the Terminal B ticketing lobby is closed, and all United Airlines Terminal B passengers must check in at Terminal C. Allow extra time and check IAH alerts for the latest updates. Also consider whether a Bush Airport parking coupon could shave another few dollars off your total before you book.
