Bush Airport Parking Garage: 2026 Rates & Terminal Guide

Back to IAH Airport Short Term Parking | Complete IAH Airport Parking Guide

A Bush Airport parking garage is a covered, multi-story parking structure operated by the Houston Airport System directly at George Bush Intercontinental Airport (IAH), offering the closest possible parking to departure gates. As of 2026, the IAH terminal garages charge $5.00 per hour with a $25.00 daily maximum — making them the most convenient on-airport option but not always the cheapest. Off-site lots near IAH start from just $6.63/day, so knowing exactly what each bush airport parking garage offers helps you decide what fits your trip.

• Terminal garages cost $5/hr, capped at $25/day — per official Houston Airport System published rates (verified June 2026).
• Three separate garages serve all five terminals: Terminal A/B Garage, Terminal C Garage, and Terminal D/E Garage.
• Valet parking is $30/day — just $5 more than the garage daily max, with added convenience.
• Ecopark lots cost $6.47–$8.31/day and include free 24/7 shuttle service, offering significant savings over garage rates.
• Off-site lots start at $6.63/day — up to 74% cheaper than the on-site garage daily rate.
• Terminal B ticketing is closed through late 2026 — all United Terminal B passengers check in at Terminal C and take the Skyway to gates.

What Are the Bush Airport Parking Garage Options at IAH?

George Bush Intercontinental Airport has three on-site terminal parking garages, each serving a specific set of terminals. All garages are managed by the Houston Airport System and connect directly to terminals via covered walkways or the airport's free internal transit systems.

Here is how the garages break down by terminal (verified June 2026):

• Terminal A/B Garage — Serves Terminal A (Alaska, American, Delta, Frontier, JetBlue, Southwest, Spirit, Sun Country) and Terminal B (United, United Express). Note: Terminal B ticketing is currently closed. United Terminal B passengers must check in at Terminal C and ride the Skyway to their gates.
• Terminal C Garage — Serves Terminal C (United Airlines, United Express). This garage is also the check-in point for Terminal B passengers during the ongoing $2.6 billion United Terminal B expansion.
• Terminal D/E Garage — Serves Terminal D (the Mickey Leland International Terminal, home to Air France, British Airways, Emirates, Lufthansa, Qatar Airways, Singapore Airlines, and more) and Terminal E (United, United Express). Terminal E got a new ticketing lobby in February 2025, so check-in is now independent from Terminal C.

To reach a garage not adjacent to your terminal, use the free Skyway (automated people mover, inside security) or the Subway (underground train, outside security). Both run 24/7 and connect all five terminals. According to IAH's official terminal parking page, accessible spaces are available on the ground level of every garage, and van-accessible stalls are also provided.

IAH has roughly 40,000 total parking spaces across all facilities — one of the largest airport parking systems in the U.S. The terminal garages represent the most convenient option but come at a premium over the ecopark lots located near John F. Kennedy Boulevard and Will Clayton Parkway.

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

The bush airport parking garage rate is $5.00 per hour, with a daily maximum of $25.00 — based on official Houston Airport System published rates (verified June 2026). That cap kicks in after five hours, so even a full day costs the same as five individual hours.

Here is how on-site and off-site options compare side by side:

For a 7-day trip, parking in the terminal garage costs $175. PreFlight Airport Parking's 7-day uncovered rate drops to just $3.99/day, totaling around $28 — a saving of over $147 for the same week, based on current published rates. For long stays, that gap is hard to ignore.

For short visits — picking someone up, a same-day trip, or a two-hour meeting — the garage's $5/hr rate is the most practical choice. You stay close, skip the shuttle, and pay only for what you use. For anything longer than a day, compare your options at Triply's IAH parking search before you commit.

Which Parking Garage Is Closest to My Terminal at Bush Airport?

Each bush airport parking garage is connected directly to its terminal, so the walk from your car to check-in is minimal. The key is parking in the right garage for your airline from the start.

• Flying American, Alaska, Delta, JetBlue, Southwest, Spirit, Frontier, or Sun Country? Use the Terminal A/B Garage. All of these airlines depart from Terminal A.
• Flying United from Terminal C? The Terminal C Garage is directly connected. If you're on United and your boarding pass says Terminal B, note that Terminal B ticketing is currently closed — park at Terminal C Garage and check in there, then take the Skyway.
• Flying internationally from Terminal D? Terminal D is the Mickey Leland International Terminal, serving airlines like Emirates, British Airways, Air France, KLM, Lufthansa, Qatar Airways, Singapore Airlines, and others. Use the Terminal D/E Garage.
• Flying United from Terminal E? The new Terminal E ticketing lobby opened in February 2025. Terminal E passengers now check in independently — use the Terminal D/E Garage.

If you arrive at the wrong garage, don't panic. The free Subway runs underground between all terminals outside security, and the free Skyway connects them above ground inside security. Both run 24/7. Allow an extra 10-15 minutes if you need to cross terminals before your flight.

On-Site Parking Garage vs. Off-Site Lots at IAH: Which Should You Choose?

The right choice depends on your trip length, budget, and how much time you have. Here is a direct comparison to help you decide.

On-Site Garage Parking

• Pro: Walk directly to your terminal — no shuttle needed.
• Pro: Covered, with accessible spaces on every ground floor.
• Pro: 24/7 operation with security monitoring and payment by cash, Visa, Mastercard, Amex, Discover, Apple Pay, or Google Pay.
• Con: At $25/day, a 5-night trip costs $125. A week costs $175.
• Con: No advance booking discount available through fly2houston.com for garages.
• Best for: Short stays (1-2 days), quick pick-ups, or travelers who need maximum convenience.

Off-Site Lot Parking

• Pro: Rates from $6.63/day (PreFlight) to $11.25/day (The Parking Spot) — significantly cheaper for multi-day trips.
• Pro: Free 24/7 shuttles with some of the best frequency in Houston — Fine Airport Parking runs every 5-7 minutes.
• Pro: Free cancellation available at most lots when booked in advance.
• Con: Adds 5-15 minutes of shuttle time each way.
• Con: Some hotel lots (Comfort Suites, Hilton Garden Inn) may have limited shuttle hours.
• Best for: Trips of 2+ days where saving $10-$18/day adds up quickly.

For a deeper look at the savings potential across every off-airport option, the IAH off-airport parking guide covers each lot's shuttle schedule, amenities, and booking tips in detail.

If you need a middle ground — covered parking with a very short shuttle — the ecopark covered lot at ~$8.31/day with a 10-15 minute free shuttle is a strong option. For more on ecopark specifically, see our sibling article on Bush Airport ecopark rates and how it works.

How Does IAH Valet Parking Service Work?

On-airport valet parking at IAH costs $30/day — only $5 more than the garage daily cap. For the added convenience, many travelers find it worthwhile. Here is how it works step by step.

1. Drive to your terminal's designated valet drop-off zone (located at the departures curb level).
2. A valet attendant meets you, takes your keys, and gives you a claim ticket.
3. Your car is parked in a secure, monitored facility managed by the Houston Airport System.
4. On return, retrieve your claim ticket and call or text the valet desk from the arrivals level.
5. Your car is brought to the arrivals curb. Payment is accepted by cash or major credit card.

Valet is available at multiple terminals. If you are flying United from Terminal C, see our full breakdown on IAH Terminal C valet parking for exact drop-off locations, pricing details, and whether it makes sense for your trip.

What Is the SurePark Guaranteed Parking Program at Bush Airport?

SurePark is an on-airport guaranteed parking reservation program offered by the Houston Airport System at IAH. It allows travelers to pre-book a guaranteed space in a specific terminal garage before arrival — removing the uncertainty of finding an open spot during busy travel periods.

Key details about SurePark (based on current Houston Airport System program information):

• Guaranteed space: Your reserved spot is held even during peak travel periods like Thanksgiving and spring break.
• How to book: Reservations are made through fly2houston.com before your trip date.
• Pricing: Based on current published rates, SurePark reservations use the standard garage rate structure ($5/hr, $25/day max). Pre-booking through the official site may unlock discounted rates — always check fly2houston.com before arriving.
• Best use case: Holiday weekends, summer peak travel, or any time IAH sees high volume — the airport serves Houston as its primary international hub and garages can fill quickly.

IAH is 23 miles north of downtown Houston and handles an enormous volume of both domestic and international passengers through five terminals. During peak seasons, on-site garages can reach capacity. Booking a SurePark space in advance is the safest way to guarantee you are parked and through security on time.

How to Save Money on the Bush Airport Parking Garage: Tips, Discounts & Booking

The bush airport parking garage does not offer discounts as generous as off-site lots — but there are still smart ways to reduce your costs at IAH. Here are the most effective strategies (verified June 2026):

• Book online through fly2houston.com: Pre-booking on the official airport site can unlock lower rates for on-airport options, including ecopark. Always check before driving in and paying at the gate.
• Use ecopark for multi-day trips: Ecopark uncovered runs ~$6.47/day vs. $25/day in the garage — that is a saving of roughly 74% for a comparable on-airport option with a free shuttle every 10-15 minutes.
• Compare off-site lots for stays of 3+ days: PreFlight's 7-day rate drops to $3.99/day uncovered — the cheapest verified option near IAH. Lock in that rate before peak travel sends prices up.
• Use TSA PreCheck to offset shuttle time: If you're saving money with an off-site lot but worried about time, TSA PreCheck can cut security wait times dramatically, easily making up for a 10-minute shuttle ride.
• Check for coupons: The Bush Airport parking coupon guide lists current promo codes for both on-airport and off-site lots — updated for 2026.
• Plan around construction delays: Terminal B ticketing is closed through late 2026, which adds extra time for United passengers. Allow at least 30 extra minutes and factor that into your parking choice and arrival time.
• Avoid peak surcharges: IAH serves a massive international hub. Garages fill fastest around major holidays and summer. Book any reservation at least a week in advance to get the best rate and availability.

Before your trip, check real-time traffic using the Waze live traffic map. Houston traffic on Interstate 69 and the Sam Houston Tollway (Beltway 8) can be severe — especially during morning and evening rush hours. Adding 15-20 minutes of buffer can be the difference between a calm airport experience and a stressful one.

Quick tip: If you are parking in the Terminal D/E Garage for an international departure, the IAH $1.46 billion Terminal Redevelopment Program is wrapping up in early 2026. The new International Central Processor (ICP) ticketing hall and security checkpoints are near completion. Signage may still be updating — follow airport staff directions and allow extra time for international check-in.

Is There EV Charging at the IAH Parking Garage?

Yes. EV charging is available at IAH, including within the on-site parking facilities. According to the IAH official EV charging page, charging stations are available for airport parkers. If you drive an electric vehicle, you can also find EV charging at Fine Airport Parking (IAH), which has 20 dedicated EV spaces in its off-site lot at $9.99/day — a good alternative if on-site chargers are occupied.

Find the Best Bush Airport Parking Garage Rate for Your IAH Trip

The bush airport parking garage is the most direct, no-shuttle option at IAH — ideal for short stays and tight schedules. At $25/day maximum per the Houston Airport System's published rates, garages make sense for 1-2 day trips. For longer stays, on-airport ecopark or off-site lots save you serious money — up to 74% less per day compared to the garage rate.

The 2026 construction at IAH adds one important reminder: Terminal B passengers are checking in at Terminal C through late 2026. Factor in extra time, check current signage, and pick the garage that matches your actual check-in terminal — not just your gate number.
