What Is the IAH Airport Parking Fee by Lot Type?

George Bush Intercontinental Airport offers five distinct parking tiers, each with its own fee structure. According to official IAH parking rates published by the Houston Airport System, the tiers are terminal garages, valet, ecopark uncovered, ecopark covered, and the free cell phone lots. Choosing the right one depends on your trip length, budget, and how close you want to be to your terminal.

The terminal garages hit their $25/day cap after just five hours. If you arrive at 9 AM and your flight is at 2 PM, you pay the full daily rate. For anything beyond one day, ecopark is almost always cheaper. For a trip of seven or more days, off-site lots beat every on-airport option by a wide margin.

How Do Terminal Garage Fees Work at IAH? (Terminal-by-Terminal Breakdown)

Every terminal garage at IAH charges the same rate — $5 per hour with a $25/day maximum — but each garage serves different terminals. Parking in the wrong garage adds unnecessary walking or requires a shuttle connection. Here is which garage covers which terminal, based on official terminal parking data from fly2houston.com:

• 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's ticketing lobby is closed through late 2026. United passengers on Terminal B flights must check in at Terminal C and use the free Skyway to reach their gate.
• Terminal C Garage — serves Terminal C (United Airlines, United Express). Currently handles check-in for Terminal B passengers as well.
• Terminal D/E Garage — serves Terminal D (Mickey Leland International Terminal: Air France, British Airways, Emirates, Lufthansa, Singapore Airlines, and more) and Terminal E (United Airlines, United Express).

The free Skyway (an automated people mover inside security) and the Subway (a free underground train outside security) connect all five terminals 24/7. So even if you park in the A/B Garage but need Terminal D, you can ride the Subway across. Still, parking closest to your terminal saves the most time — especially with checked bags. The United Airlines $2.6 billion Terminal B expansion is ongoing, with the Terminal B North concourse projected to complete in 2026. No parking closures are expected during construction.

Ecopark Fees: IAH's Best On-Airport Value

Ecopark is IAH's budget-friendly on-airport parking option, offering rates significantly below the terminal garages. The uncovered ecopark on John F. Kennedy Boulevard runs approximately $6.47/day. The covered ecopark 2 on Will Clayton Parkway runs approximately $8.31/day. Both locations include a free 24/7 shuttle to all terminals, running every 10-15 minutes, per Houston Airport System data.

Compared to the terminal garage's $25/day cap, ecopark uncovered saves you roughly $18.53 per day — that's a 74% savings for trips of two or more days. On a 7-day trip, ecopark uncovered costs about $45 versus $175 at the terminal garage. That difference alone covers a nice dinner when you land. Pre-booking online at fly2houston.com can unlock further discounts on ecopark rates.

A detail most competitors miss: ecopark has a short grace period for free parking. If you pull in, realize you forgot something, and leave within the first few minutes, you won't be charged. Always check the posted signage at the booth for the current grace period. For longer trips, ecopark covered is worth the ~$1.84/day premium over uncovered — Houston summers are brutal, and shade matters for a car sitting a week in the heat.

Off-Site IAH Parking Fees vs. On-Airport: Full Cost Comparison

Off-site lots near IAH consistently beat on-airport prices, especially for trips longer than three days. Based on our analysis of verified rates across six major off-site providers (June 2026), here is the complete side-by-side comparison:

PreFlight Airport Parking offers the lowest verified off-site rate at $3.99/day uncovered on a 7-day booking — that's a savings of more than $121 versus the terminal garage on a one-week trip. Fine Airport Parking has the most frequent shuttle service at every 5-7 minutes, which matters for early morning or late-night flights. Fast Park & Relax is the best covered off-site option under $11/day. All six lots offer free cancellation, so there's no risk in booking early.

Hotel-and-Park Packages: Are They Worth the Fee?

Hotel-and-park packages bundle one night's stay with multi-day parking. The Comfort Suites Houston IAH Airport and Hilton Garden Inn Houston/Bush IAH both offer this setup at $8.95/day and $9.95/day respectively. These make the most sense if you have an early morning flight and live far from IAH — you stay the night before, leave your car, and take the hotel shuttle to the terminal. For a 5-day trip, you pay the hotel rate (typically $80-$120/night) plus the daily parking fee, which can still come out cheaper than taxi plus parking combined. Check ParkSleepFly for current hotel-and-park package availability near IAH.

How to Book IAH Parking and Unlock Lower Fees

Pre-booking IAH parking is the single easiest way to lower your IAH airport parking fee. The Houston Airport System lets you reserve ecopark and terminal garage spots online at fly2houston.com, where pre-paid rates are often discounted versus drive-up prices. Off-site lots offer even deeper discounts when booked in advance — PreFlight's 7-day rate of $3.99/day is only available when you pre-book.

1. Compare rates first. Use Triply's IAH parking search to see all on-site and off-site options side by side, with exact daily and weekly totals.
2. Pick your lot and dates. Enter your arrival and departure times precisely — most lots calculate fees by the day, not the hour, so an extra partial day can add a full day's charge.
3. Book with free cancellation. All six verified off-site lots offer free cancellation. Book early and cancel if your plans change.
4. Save your confirmation. Screenshot or print your reservation. Some lots use a QR code at the entrance; others ask for your booking number at the gate.
5. Check payment methods. IAH parking accepts cash, Visa, Mastercard, Amex, Discover, Apple Pay, and Google Pay. Most off-site lots do the same.

For anyone enrolled in TSA PreCheck, factor in the time savings at security when budgeting your arrival window. Shorter security lines mean you can leave the car later — which matters if you're paying by the hour in a terminal garage. The Global Entry program is worth considering for frequent international travelers departing from IAH Terminal D, since CBP's expedited re-entry can save significant time on return.

Seasonal and Peak Travel: Does the IAH Parking Fee Change?

IAH's on-airport parking rates are set by the Houston Airport System and do not formally change for holidays. However, availability tightens sharply during Thanksgiving week, the Christmas–New Year's window, spring break (March), and the summer travel peak (June–August). With roughly 40,000 total parking spaces across all IAH facilities, lots still fill during peak periods — especially ecopark, which is the most popular economy option.

Off-site lots can also see reduced availability during peak weeks. Dynamic pricing means some lots charge more when availability drops. Travelers frequently report that booking 2-3 weeks out during summer or holiday periods saves both money and stress. Pre-booking also guarantees your spot — you won't circle ecopark looking for a space at 4 AM before a Thanksgiving flight.

Houston weather adds another variable. Hurricane season runs June through November. Tropical storms can flood low-lying parking areas and snarl traffic on I-69 and Beltway 8. Before driving to IAH, always check real-time traffic on Waze — Houston traffic can be severe even on a normal day, and the airport is 23 miles north of downtown with a 25-40 minute drive under normal conditions. Budget extra time during storm systems.

Insider Tips to Reduce Your IAH Airport Parking Fee

Frequent IAH travelers develop habits that cut parking costs significantly. Here are the most practical ones, based on current lot data and traveler experience:

• Use the 7-day rate at PreFlight. The jump from $5.78/day to $3.99/day for a 7-day uncovered booking saves over $12 on a one-week trip versus the standard daily rate.
• Avoid the terminal garage for trips over 2 days. At $25/day, a 5-day stay costs $125. Ecopark covered costs about $41.55 for the same period — a 66% savings.
• Fine Airport Parking is best for red-eye or late-night flights. Its shuttle runs every 5-7 minutes, 24/7 — the highest frequency of any off-site lot near IAH.
• Remember Terminal B check-in is closed. All Terminal B (United Airlines) passengers must check in at Terminal C through late 2026. Park in the Terminal C Garage or allow extra Skyway transfer time if you park in the A/B Garage.
• EV drivers: Fine Airport Parking offers 20 EV charging spaces on-site. IAH terminal garages also have EV charging — check the IAH EV charging page for current stall locations before booking.
• Accessible parking is available on the ground level of all terminal garages and in ecopark lots. Van-accessible spaces are available at each location.
• Use the cell phone lot for free. If you're picking someone up, wait at 17010 John F. Kennedy Boulevard or 4500 Will Clayton Parkway for free. Do not park in the terminal garage while waiting — fees add up fast.
• Book off-site for corporate travel. Many off-site lots offer corporate accounts with monthly billing. If your company reimburses parking, a covered spot at The Parking Spot ($11.25/day) or Fast Park & Relax ($10.95/day) is easier to expense than a stack of daily receipts.

IAH Parking Fee Duration Breakdown: 1 Day to 14 Days

Parking costs at IAH vary dramatically by trip length. The table below shows actual total costs across key durations, using verified 2026 rates, so you can pick the best option for your specific trip without doing the math yourself.

The data is clear: the terminal garage is only cost-competitive for trips under 5 hours (when you might not hit the daily cap). For anything overnight or longer, ecopark or an off-site lot wins on price every time. A 14-day trip at the terminal garage costs $350 — nearly $294 more than PreFlight's 7-day extended rate. According to Bureau of Transportation Statistics data, IAH is one of the busiest airports in the United States, meaning parking demand — and the value of smart pre-booking — is consistently high.

How to Exit IAH Parking: Payment and Fee Settlement

Exiting IAH parking is straightforward but a few details help you avoid delays. Terminal garages and ecopark use automated pay stations located both inside the garage and at the exit lanes. You can pay by cash, Visa, Mastercard, Amex, Discover, Apple Pay, or Google Pay. If you pre-booked online, your confirmation barcode scans at the exit gate. Off-site lots typically settle payment when you return to pick up your car — most accept the same payment methods.

If you lose your parking ticket, go to the parking office before heading to the exit. Staff can look up your entry time using camera records. Lost ticket fees vary, so keeping your receipt or pre-booking confirmation avoids this hassle entirely. Most lots do not charge an exit fee beyond the standard daily rate — the rate you see when you enter is what you pay.

For the latest alerts on any temporary closures or fee changes at IAH due to ongoing construction, check the IAH alerts page before your travel day. The $1.46 billion Terminal Redevelopment Program is in its final phase as of 2026, but no parking closures are currently expected.
