Intercontinental Airport Parking Garage: 2026 Full Guide

An intercontinental airport parking garage at George Bush Intercontinental Airport (IAH) is a multi-level, on-airport structure that gives travelers covered or open-deck parking within walking distance of their terminal. Terminal garages cost $5/hour with a $25/day maximum, per published rates from the Houston Airport System. IAH operates three garage complexes — Terminal A/B, Terminal C, and Terminal D/E — covering all five terminals across roughly 40,000 total parking spaces. Off-airport lots start as low as $6.63/day, so your best choice depends on your terminal, trip length, and budget.

• Three on-airport garages serve all five terminals: A/B Garage, C Garage, and D/E Garage.
• Hourly rate is $5/hr, capped at $25/day for terminal garage parking (verified June 2026).
• Valet parking runs $30/day — the most expensive on-airport option, but fastest for drop-off.
• ecopark and ecopark 2 offer the cheapest on-airport rates: uncovered ~$6.47/day and covered ~$8.31/day.
• Off-airport lots start at $6.63/day (PreFlight Airport Parking) with free 24/7 shuttles.
• Terminal B ticketing is closed through late 2026 — all Terminal B passengers check in at Terminal C.

What Are the Parking Garages at IAH and Which Terminal Do They Serve?

IAH has three separate garage complexes, each assigned to specific terminals. Parking in the right garage saves you a long walk — or an extra shuttle connection — so knowing the layout before you arrive matters.

• Terminal A/B Garage — Serves Terminal A (Alaska Airlines, American Airlines, Delta, Frontier, JetBlue, Southwest, Spirit, Sun Country) and Terminal B (United Airlines, United Express). Note: Terminal B ticketing is closed through late 2026. United passengers on Terminal B flights must check in at Terminal C and ride the Skyway to their gate.
• Terminal C Garage — Serves Terminal C (United Airlines, United Express). This garage is the busiest check-in hub in 2026 because Terminal B passengers also route through here.
• Terminal D/E Garage — Serves Terminal D (Mickey Leland International Terminal, home to Air France, British Airways, Emirates, Lufthansa, Qatar Airways, Singapore Airlines, and others) and Terminal E (United Airlines, United Express). Terminal E now has its own ticketing lobby, opened February 2025, so you no longer need to check in at Terminal C.

Once parked, the free Skyway automated people mover and the free Subway underground train both connect all five terminals around the clock. If you park at the wrong garage by mistake, take either free transit connection rather than moving your car.

How Much Does the Intercontinental Airport Parking Garage Cost? (Hourly, Daily & Long-Term Rates)

According to official Houston Airport System published rates, the terminal garages charge $5 per hour with a $25 per day maximum. That rate applies to all three garage complexes (A/B, C, and D/E) as of June 2026.

A one-week trip at the garage rate comes to $175. That's significantly more than ecopark's covered rate (~$58 for seven days) or a pre-booked off-airport lot. For trips longer than two days, most travelers find the cost difference hard to justify. Pre-booking online at fly2houston.com can unlock discounts on garage rates — worth checking before you go.

On-Airport Intercontinental Airport Parking Garage vs. Off-Airport Parking: Which Is Better?

The garages win on convenience. Off-airport lots win on price. Your trip length usually decides the right call.

On-Airport Terminal Garages

• Walk directly to your terminal — no shuttle wait required.
• Covered, climate-controlled (mostly), and open 24/7.
• Accessible parking on ground level of every garage.
• Best for trips under 2 days, red-eye flights, or early morning departures.
• At $25/day, a 5-day trip costs $125.

Off-Airport Lots with Shuttle Service

• PreFlight Airport Parking: from $6.63/day, shuttle every 5-8 min drive from airport.
• Fine Airport Parking: $9.99/day, shuttle every 5-7 minutes — fastest off-airport frequency.
• Fast Park & Relax: $10.95/day, covered parking, shuttle every 10-15 minutes.
• The Parking Spot: $11.25/day covered, shuttle every 15 minutes, picks up at your car.
• Based on our analysis, a 5-day stay at PreFlight costs around $33 — saving roughly 74% vs the terminal garage.

The trade-off is shuttle time. Off-airport lots are 4-8 minutes away by vehicle, plus 5-15 minutes for the shuttle to depart. Budget an extra 20-30 minutes each way. If your flight is early or you're traveling with heavy bags, the garage's walk-in convenience has real value. For longer trips, the savings from off-airport parking are hard to ignore.

For a deeper breakdown of long-term savings, see our IAH long term parking rates guide — it compares every lot for trips from 3 to 14 days.

How Do You Get from the IAH Parking Garage to Your Terminal?

Each garage connects directly to its assigned terminal by an indoor walkway or skybridge — no shuttle needed. The walk from your parked car to the check-in counter is typically 3-8 minutes depending on your floor level.

1. Park in the garage that matches your terminal (A/B, C, or D/E).
2. Follow the color-coded signs to the terminal connector.
3. Cross into the terminal building and proceed to your airline's check-in desk.
4. Need a different terminal? Take the free Skyway (above-ground, inside security) or the free Subway (underground, outside security) — both run 24/7.

One 2026 note: Terminal B's ticketing lobby is closed through late 2026. United Airlines passengers on B-terminal flights should park at the Terminal C Garage, check in at Terminal C, and take the Skyway to their Terminal B gate. The Houston Airport System advises adding extra time for this routing.

If you're flying into IAH and someone is picking you up, the cell phone lots are the free waiting option. One is at 17010 John F. Kennedy Boulevard; the second is at 4500 Will Clayton Parkway. Both are free and monitored.

Before your trip, review TSA security screening guidelines so you know what to expect at the checkpoints. Arriving with the right items packed will save time after you've parked.

Is Valet Parking at George Bush Intercontinental Airport Worth It?

Valet parking at IAH costs $30/day — the most expensive on-airport option. You pull up to the terminal curb, hand off your keys, and walk straight to check-in. No hunting for a space, no carrying bags through a garage.

Valet makes the most sense when:

• You're running late and every minute counts.
• You have heavy luggage or mobility limitations.
• You're on a short trip (1-2 days) and want maximum ease.
• You're dropping off a passenger and leaving immediately.

For trips of 5 days or more, valet adds up to $150+. At that price point, even a covered off-airport lot with a shuttle saves you over $100. Travelers who use valet most often are on same-day or overnight business trips where speed matters more than cost.

How to Reserve IAH Parking in Advance and Save Money

Pre-booking your parking at the intercontinental airport parking garage — or at an off-airport lot — is one of the easiest ways to lock in a lower rate. Online rates at fly2houston.com are typically lower than the posted drive-up rate at the garage.

• Book at fly2houston.com for official on-airport discounts.
• Compare off-airport lots on Triply to see all options side by side.
• Most lots offer free cancellation, so there's no risk in booking early.
• Book at least 1-2 weeks ahead during peak periods: summer, spring break, Thanksgiving, and Christmas.
• Look for 7-day rates — PreFlight's 7-day uncovered rate drops to just $3.99/day, for example.

Payment at IAH garages accepts cash, Visa, Mastercard, Amex, Discover, Apple Pay, and Google Pay — so you have plenty of options on exit.

What Are the Best Off-Airport Parking Alternatives Near IAH?

Six verified off-airport lots serve George Bush Intercontinental Airport with free 24/7 shuttle service (verified June 2026). Rates range from $6.63/day to $11.25/day — all significantly below the $25/day terminal garage maximum.

Fine Airport Parking runs the most frequent shuttle in this group — every 5-7 minutes — and also offers EV charging with 20 dedicated spaces. The Parking Spot includes Spot Club rewards points and picks up at your car, which reduces the walk from your space to the shuttle stop. All six lots include free cancellation, so you can book early without risk.

Before you drive to the airport, check real-time traffic on Waze — IAH is 23 miles north of downtown Houston, and Houston traffic can add 15-30 minutes to your drive without warning.

IAH Parking Tips: EV Charging, Oversized Vehicles, and Accessibility

The intercontinental airport parking garage system at IAH covers several special needs beyond standard parking. Here's what to know before you arrive.

EV Charging

EV charging stations are available at IAH terminal parking facilities. For details on charger locations, the Houston Airport System EV charging page has current information. Off-airport, Fine Airport Parking provides 20 dedicated EV charging spaces — a solid option if you want to charge while you travel.

Accessible Parking

Accessible parking spaces are available on the ground level of every terminal garage and in both ecopark lots. Van-accessible spaces are included. The ground-level location means no elevator required for travelers who prefer to avoid them.

Oversized Vehicles

If you're driving a tall truck, lifted SUV, or oversized vehicle, check garage height clearances before entering. Our Bush Airport parking garage height guide covers exact limits for each structure and explains your alternatives if your vehicle doesn't fit. Off-airport open lots are often the better fit for large vehicles.

TSA PreCheck and Security

If you have TSA PreCheck, you can move through security faster after parking — useful when the Terminal C garage is busy due to the Terminal B check-in overflow. Allow extra time in 2026 because both Terminal B and Terminal C passengers are funneling through Terminal C checkpoints.

Construction Impact in 2026

IAH is mid-way through a $1.46 billion Terminal Redevelopment Program and a separate $2.6 billion United Airlines Terminal B expansion. No parking garage closures are expected in 2026, per Houston Airport System updates. The main traveler impact is the Terminal B lobby closure — plan for extra time if you're flying United.
