IAH Long Term Parking Rates: Full 2026 Guide

IAH long term parking rates are the daily or weekly costs charged for leaving your car at George Bush Intercontinental Airport for four or more days. As of 2026, IAH long term parking rates range from roughly $3.99/day (pre-booked off-site) up to $25/day (on-airport terminal garages), per published rates from the Houston Airport System and verified off-site lot data. The Complete IAH Airport Parking Guide covers all options at a high level — this article goes deep on long-term stays, comparing every lot, shuttle, and booking strategy.

• Cheapest long-term option: PreFlight Airport Parking starts at $3.99/day on a 7-day pre-booked rate (uncovered).
• Best on-airport value: ecopark uncovered runs ~$6.47/day; ecopark covered runs ~$8.31/day — both include free 24/7 shuttle service every 10-15 minutes.
• Terminal garages cost $5/hour, capped at $25/day — expensive for long stays but steps from your terminal.
• Off-site lots range from $6.63–$11.25/day and all include free 24/7 shuttle service to IAH terminals.
• Book in advance online at fly2houston.com or through a comparison tool to unlock the lowest rates.
• Construction alert (2026): Terminal B ticketing is closed — all United/Terminal B passengers check in at Terminal C. Allow extra time.

How Much Do IAH Long Term Parking Rates Cost in 2026?

IAH long term parking rates vary significantly depending on whether you park on-airport or off-site, and whether you book in advance. On-airport terminal garages cost $25/day (the daily maximum), making a 7-day trip cost $175 before any discounts, per the Houston Airport System's official parking rates. Off-site pre-booked lots cut that cost dramatically — sometimes by more than 80%.

The ecopark lots sit in the middle of the price range. Ecopark uncovered costs approximately $6.47/day, while ecopark covered runs ~$8.31/day (verified June 2026). These are on-airport facilities, so you avoid driving off-site. The free shuttle runs every 10-15 minutes around the clock. For a 7-day trip, ecopark uncovered totals roughly $45 — versus $175 in a terminal garage.

Off-site lots offer the widest price spread. PreFlight Airport Parking's 7-day rate drops to $3.99/day for uncovered, the lowest verified rate available near IAH. At the higher end, The Parking Spot (covered) runs $11.25/day. All six verified off-site lots include free 24/7 shuttles to all terminals. Use Triply to compare IAH long term parking rates side-by-side and lock in your best price before your trip.

Terminal-by-Terminal Breakdown: Which Garage Serves Your Flight?

IAH has five terminals and roughly 40,000 total parking spaces across all facilities, per the Houston Airport System. Each terminal garage serves specific airlines, so parking in the right garage saves walking time. Here is how the garages line up:

• Terminal A/B Garage → Serves Terminals A and B. Terminal A covers Alaska Airlines, American Airlines, Delta, Frontier, JetBlue, Southwest, Spirit, and Sun Country. Terminal B serves United Airlines and United Express.
• Terminal C Garage → Serves Terminal C (United Airlines and United Express). Note: Terminal B passengers must check in at Terminal C through late 2026 due to the ongoing $2.6B United Terminal B expansion.
• Terminal D/E Garage → Serves Terminals D and E. Terminal D (Mickey Leland International Terminal) handles all international carriers including Emirates, Lufthansa, British Airways, Singapore Airlines, Qatar Airways, Korean Air, and more. Terminal E serves United Airlines and United Express.

All five terminals connect via the free Skyway (above ground, inside security) and the free Subway (underground, outside security). So even if you park in the wrong garage, you can reach your terminal without leaving the airport campus. For long-term stays, the terminal garages cost $25/day maximum — use the ecopark instead unless proximity is critical.

The Terminal E Ticketing Lobby opened in February 2025 with a new departures curb and independent check-in. Terminal B's ticketing lobby remains closed through late 2026 — all Terminal B passengers must check in at Terminal C and ride the Skyway to their gate. Allow an extra 15-20 minutes if you're flying United out of Terminal B. Check the IAH redevelopment page for the latest construction updates.

Ecopark vs. Ecopark 2: IAH's Best On-Airport Long-Term Value

IAH's ecopark and ecopark 2 are the airport's dedicated economy parking lots, designed for multi-day travelers who want on-airport convenience without terminal garage prices. Ecopark on JFK Boulevard offers both uncovered (~$6.47/day) and covered (~$8.31/day) spaces. Ecopark 2 on Will Clayton Parkway provides additional capacity. Both lots run a free 24/7 shuttle to all five terminals, with pickups approximately every 10-15 minutes (verified June 2026).

For a 7-day trip, ecopark uncovered costs roughly $45 total — a savings of about 74% compared to the terminal garage ($175 for 7 days). That is real money. The shuttle ride adds a few extra minutes compared to walking from a garage, but most travelers find the trade-off worthwhile. Accessible parking is available on the ground level of ecopark lots, with van-accessible spaces included.

You can pre-book ecopark parking at fly2houston.com to lock in your spot and access online discounts. Walk-up rates are available too, but advance booking during busy travel periods is strongly recommended. If you are weighing ecopark against hotel park-and-fly packages, our IAH airport hotel parking guide shows exactly how bundled hotel-and-park deals compare on total cost.

Off-Site IAH Parking Lots: Long-Term Options Compared

Off-site parking lots near IAH are private facilities located 4-10 minutes from the airport that offer shuttle service to all terminals. They consistently offer the lowest IAH long term parking rates available. Based on our analysis of verified lot data, off-site lots range from $6.63/day to $11.25/day — well below the on-airport garage maximum of $25/day.

Shuttle Frequency Matters for Long Stays

Shuttle wait times vary by lot. This matters most when you return late at night after a long trip. Here is a quick comparison by shuttle frequency:

• Fine Airport Parking (IAH): Shuttles every 5-7 minutes — the best frequency of any lot near IAH. Located 5-8 minutes from the airport. Also offers EV charging (20 spaces) and valet service. Rate: $9.99/day.
• PreFlight Airport Parking (IAH): 24/7 shuttle, 5-8 minutes from airport. Best price at $6.63/day standard ($3.99/day pre-booked 7-day uncovered rate). Gated, well-lit, 24/7 security cameras.
• Fast Park & Relax (IAH): Shuttle every 10-15 minutes, covered parking, 4-6 minutes from airport. Staffed 24/7 with luggage assistance. Rate: $10.95/day.
• The Parking Spot (IAH): Shuttle every 15 minutes, 4-7 minutes from airport. Spot Club rewards program. Covered option $11.25/day; uncovered $8.75/day. Includes free water bottle.
• Comfort Suites Houston IAH Airport (Parking): Hotel lot, shuttle during operating hours. Rate: $8.95/day. Good option for early-morning departures after an overnight stay.
• Hilton Garden Inn Houston/Bush IAH (Parking): Hotel lot with shuttle to terminals. Rate: $9.95/day. Handicap accessible.

Fine Airport Parking's 5-7 minute shuttle frequency stands out for travelers who hate waiting. For pure price, PreFlight wins. For covered protection from Houston's summer storms and hail, Fast Park & Relax and Fine Airport Parking both offer solid covered options.

How to Book IAH Long-Term Parking (and Save Money Doing It)

Booking IAH parking in advance is the single most effective way to lower your total cost. Pre-booking can reduce rates by 40-80% compared to walk-up prices, based on current lot data — PreFlight's 7-day uncovered rate drops from $5.78/day to $3.99/day when booked in advance. For on-airport ecopark, fly2houston.com offers online discounts that are not available at the gate.

1. Compare rates first. Use Triply's IAH parking search to see all available lots, real-time prices, and amenities side by side.
2. Select your dates precisely. Enter your exact departure and return times. Many lots charge by the day, so even a few hours over can add a day's rate.
3. Choose covered vs. uncovered. Houston gets severe summer thunderstorms and occasional hail. Covered parking costs a few dollars more per day but can protect your vehicle. Ecopark covered runs about $1.84/day more than uncovered — worth it for week-long trips during storm season.
4. Check the cancellation policy. All six verified off-site lots listed here offer free cancellation. On-airport pre-bookings through fly2houston.com also typically allow changes. Always read the terms before paying.
5. Confirm shuttle pickup instructions. Most lots send a confirmation email with shuttle pickup details. Save it on your phone so you have it when you return.

For on-airport parking, book at fly2houston.com. For off-site lots with the lowest IAH long term parking rates, Triply aggregates options from multiple providers so you see the best available price. Look for promo codes during the booking process — off-site lots frequently run limited-time discounts, especially in January and September (historically slower travel months in Houston).

If you drive to IAH often, consider joining The Parking Spot's Spot Club rewards program, which earns points toward free parking days. Fine Airport Parking also has a loyalty program for frequent parkers. These memberships pay off quickly for business travelers who fly monthly.

Seasonal Pricing and Peak Travel: When IAH Parking Fills Up

IAH serves as United Airlines' second-largest hub, and it handles heavy international traffic year-round. Parking demand — and sometimes pricing — spikes at predictable times. According to FAA aviation statistics, IAH is consistently one of the top 10 busiest U.S. airports by total operations, which makes peak-period planning essential.

The highest-demand periods for IAH parking are:

• Thanksgiving week (late November): All lots, including ecopark, can fill to capacity. Book at least 2-3 weeks in advance.
• Christmas and New Year's (Dec 20 – Jan 2): The busiest stretch of the year. Off-site lots sell out. Rates may increase. Book a month ahead.
• Spring Break (mid-March): Heavy family travel. IAH sees surges for both domestic and international flights.
• Summer travel season (June – August): Sustained high demand. Houston heat also makes covered parking more appealing. Ecopark covered and Fast Park's covered garage are popular.
• Major Houston events: Rodeo Houston (late February–March), Houston Livestock Show, and large conventions at the George R. Brown Convention Center can add unexpected pressure on airport parking during otherwise slower periods.

Houston weather is another factor. Summer afternoons bring severe storms and occasional hail. If you are parking for a week or more and a storm season is active, the extra cost of covered parking — roughly $2-4/day more — can be worthwhile protection. Check forecasts before your trip and check real-time traffic on Waze before you drive to the airport, as Beltway 8 and JFK Boulevard can back up quickly during bad weather or rush hour.

Insider Tips for Long-Term IAH Parking

Frequent IAH travelers develop a system. Here are the most useful tactics, based on what regular flyers at this airport have learned:

• Take a photo of your parking spot. IAH's ecopark lots and some off-site lots are large. A photo of your row and space number takes two seconds and saves real stress on return.
• Allow extra time for ecopark. The shuttle is free and frequent, but factor in 10-15 minutes for pickup plus the ride to your terminal. For a 6 AM flight, leave home earlier than you think you need to.
• United Terminal B passengers: check in at Terminal C. The Terminal B ticketing lobby is closed through late 2026. Park at the Terminal A/B or C garage, check in at Terminal C, and use the Skyway to reach your gate. Do not show up at Terminal B expecting to check bags — you will be redirected.
• Ask about weekly rate caps. PreFlight's 7-day pre-booked rate is significantly lower than their standard daily rate. Always check if a weekly or extended-stay rate is available before booking day by day.
• EV drivers: Fine Airport Parking has 20 EV charging spaces. On-airport EV charging is also available — check IAH's EV charging page for current stall locations.
• TSA PreCheck speeds up your airport time. If you are already saving time with efficient parking, pair it with TSA PreCheck to move through security faster — especially useful when the Terminal B construction flow adds extra walking at Terminal C.
• Keep your parking confirmation on your phone. Off-site lots require either a printed or digital barcode to enter. Lost confirmations cause delays at the gate.
• Valet is for short stays or convenience, not savings. At $30/day, IAH valet adds up to $210 for a 7-day trip. Use it only when speed at arrival and departure justifies the premium.

One thing many travelers overlook: the Subway (underground train) connects all terminals outside security, which means you can reach any terminal from any parking area without going through TSA. This is useful for drop-offs, pickups, or if you are connecting between terminals after a long-haul flight. The Skyway handles the same job inside security. Both run 24/7 and are free.

Is IAH Long Term Parking Safe and Secure?

Security features vary by lot type, and this is an area most IAH parking articles skip entirely. On-airport terminal garages are part of the airport campus, with airport authority oversight, regular patrol, and security cameras throughout. Ecopark lots are also on-airport with monitored facilities. For a multi-week absence, on-airport lots offer strong peace of mind.

Off-site lot security ranges from basic to robust. Here is what the verified lots offer:

• Fine Airport Parking (IAH): 24/7 security staff on-site, surveillance cameras, ADA accessible, fenced perimeter.
• PreFlight Airport Parking (IAH): Gated facility, well-lit, 24/7 monitoring, security cameras.
• Fast Park & Relax (IAH): 24/7 staffed, security cameras, luggage assistance available.
• The Parking Spot (IAH): Fenced lots, well-lit, Spot Club member tracking.
• Comfort Suites and Hilton Garden Inn lots: Hotel security cameras, gated access, lower foot traffic than stand-alone lots.

For trips longer than 10 days, covered parking in a 24/7-staffed lot is the safest bet. Houston summers are harsh on vehicles left in uncovered lots — UV damage, heat, and storm risk all increase with time. Fine Airport Parking and Fast Park & Relax both offer covered, 24/7-staffed options at competitive rates.

Final Thoughts on IAH Long Term Parking Rates

The best IAH long term parking rates come from booking off-site in advance. PreFlight Airport Parking's 7-day uncovered rate of $3.99/day is the lowest verified option near George Bush Intercontinental Airport as of 2026. Ecopark sits just behind at ~$6.47/day uncovered, with the advantage of being on-airport property. Terminal garages cost the most ($25/day maximum) and are best reserved for short stays or when terminal proximity is worth the premium.

The difference between the cheapest and most expensive long-term options is dramatic. A 7-day trip in a terminal garage costs $175. That same trip at PreFlight's 7-day rate costs roughly $28 — a saving of more than $145. Even ecopark saves over $130 compared to the garage for a week-long stay. Advance booking, covered vs. uncovered selection, and shuttle frequency all factor into your total travel experience — not just the sticker price.
