Back to IAH Airport Parking Fee Guide | Complete IAH Airport Parking Guide

IAH car parking is the system of on-airport garages, economy lots, valet services, and off-site private facilities serving George Bush Intercontinental Airport — with rates ranging from free (cell phone lot) up to $30/day for valet, and off-site options starting at just $6.63/day with a free shuttle. According to published rates from the Houston Airport System, the terminal garages cost $5/hour with a $25/day maximum, while the ecopark economy lots run ~$6.47/day uncovered and ~$8.31/day covered. If you want the cheapest drive-up option without leaving airport property, the ecopark is it. Pre-booking an off-site lot cuts costs even further — up to 55% less than the terminal garage daily max, based on current Triply rates.

• Terminal Garages: $5/hour, capped at $25/day — best for short stays under 5 hours
• Ecopark (economy lots): ~$6.47/day uncovered, ~$8.31/day covered — best on-airport value for multi-day trips
• Valet Parking: $30/day — most convenient, but the priciest on-airport option
• Off-site lots: $6.63–$11.25/day with free 24/7 shuttles — best overall value for most travelers
• Pre-booking saves money: PreFlight Airport Parking drops to $3.99/day on a 7-day rate (verified June 2026)
• IAH has ~40,000 parking spaces across all facilities, per the Houston Airport System

How Much Does IAH Car Parking Cost in 2026?

IAH car parking rates in 2026 range from $6.47/day at the on-airport ecopark to $30/day for valet, with off-site lots offering the lowest daily rates overall. Here is a full breakdown of every option, based on official Houston Airport System data and verified lot rates (verified June 2026).

The terminal garage daily cap of $25 sounds reasonable for one night. But for a 5-day trip, that adds up to $125 — versus $33.15 at PreFlight Airport Parking. That is a savings of nearly $92 for the same trip, based on our analysis of current rates.

What Are the Different IAH Car Parking Options?

George Bush Intercontinental Airport offers four main categories of parking: terminal garages, ecopark economy lots, on-airport valet, and off-site private lots. Each serves a different type of traveler.

Terminal Garages

There are three terminal garages on airport property. The Terminal A/B Garage serves Terminals A and B. The Terminal C Garage serves Terminal C. The Terminal D/E Garage serves Terminals D and E. All three charge $5/hour with a $25/day maximum. They connect to terminals via the free Skyway (inside security, above ground) or the free Subway (underground, outside security). These are ideal if you need quick, walkable access — especially for short-term parking under five hours.

Ecopark Economy Lots

IAH operates two ecopark lots. Ecopark sits on John F. Kennedy Boulevard near the airport entrance — uncovered at around $6.47/day. Ecopark 2 is on Will Clayton Parkway — covered at around $8.31/day. Both run a free 24/7 shuttle every 10–15 minutes to all terminals. For trips of two days or longer, ecopark beats the terminal garage on price. The Houston Airport System recommends pre-booking online at fly2houston.com for discounted rates.

Off-Site Private Lots

Six verified off-site lots operate near IAH, ranging from $6.63/day to $11.25/day. All include free 24/7 shuttle service. Fine Airport Parking has the most frequent shuttle — every 5–7 minutes. PreFlight Airport Parking offers the lowest 7-day rate at just $3.99/day uncovered (verified June 2026). These lots sit between 4 and 10 minutes from the airport by shuttle. For a deeper look at the off-site options, see our guide to IAH off-airport parking lots and 2026 rates.

Which IAH Parking Lot Is Closest to My Terminal?

The closest parking to your terminal depends on which airline you fly. Use the garage assigned to your terminal for the fastest walk — then take the Skyway or Subway if you need to connect.

• Terminal A (American, Delta, Southwest, JetBlue, Spirit, Frontier, Alaska, Sun Country) → Terminal A/B Garage
• Terminal B (United, United Express) → Terminal A/B Garage — but note: the Terminal B ticketing lobby is closed through late 2026. All Terminal B passengers must check in at Terminal C and take the Skyway to gates. Allow extra time.
• Terminal C (United, United Express) → Terminal C Garage
• Terminal D (international carriers: Air France, British Airways, Emirates, Lufthansa, Singapore Airlines, and more) → Terminal D/E Garage
• Terminal E (United, United Express) → Terminal D/E Garage — Terminal E now has its own ticketing lobby (opened February 2025) and no longer requires Terminal C check-in.

If you park in the wrong garage, use the free Skyway or Subway to reach your terminal. Both run 24/7 and connect all five terminals. The Skyway runs above ground inside security; the Subway runs underground outside security. Plan an extra 10–15 minutes if you need to transfer between terminals, especially given active construction in Terminal B as part of United's $2.6 billion expansion project.

How Much Can You Save by Pre-Booking IAH Parking?

Pre-booking IAH parking consistently saves money compared to paying at the gate on arrival. The savings are especially large for multi-day trips.

Here is a worked example for a 7-day trip, comparing drive-up vs. pre-booked rates based on current published rates:

• Terminal Garage (drive-up): $25/day × 7 = $175 total
• Ecopark uncovered (pre-book online): ~$6.47/day × 7 = ~$45 total
• PreFlight Airport Parking (7-day pre-book rate): $3.99/day × 7 = $27.93 total

Pre-booking the cheapest off-site lot saves you over $147 on a one-week trip versus the terminal garage. Even choosing the on-airport ecopark over the garage saves $130 for the same trip.

What Are the Best Off-Airport IAH Car Parking Rates Near the Airport?

The best off-airport IAH car parking rates come from six verified private lots, all within 4–10 minutes of the terminals by shuttle. Here is how they compare on price, shuttle speed, and key features:

• PreFlight Airport Parking (IAH) — From $6.63/day (or $3.99/day on a 7-day rate). Uncovered and covered options. Free 24/7 shuttle. Gated, well-lit, with security cameras. Best for budget travelers on longer trips.
• Comfort Suites Houston IAH Airport — $8.95/day. Hotel lot with security cameras and gated access. Good choice if you want hotel amenities nearby.
• Hilton Garden Inn Houston/Bush IAH — $9.95/day. Uncovered, self-park. Handicap accessible. Free shuttle to terminals.
• Fine Airport Parking (IAH) — $9.99/day. Fastest shuttle frequency in the area at every 5–7 minutes. Luggage assistance, EV charging (20 spaces), and valet service available. ADA accessible.
• Fast Park & Relax (IAH) — $10.95/day. Covered parking — great for Houston's heat and summer storms. 24/7 staffed, luggage assistance.
• The Parking Spot (IAH) — From $11.25/day covered. Spot Club Rewards program. Shuttle picks up at your car — no dragging bags to a bus stop.

All six lots offer free cancellation, so there is no risk in booking early to lock in a lower rate. For travelers planning a week-long trip or more, see our full breakdown of IAH long-term parking rates for 2026.

Is There EV Charging Parking Available at IAH?

Yes — EV charging is available both on airport property and at select off-site lots near IAH. The Houston Airport System provides EV charging stations in the terminal garages; check the official IAH EV charging page for current stall locations and availability. Off-site, Fine Airport Parking offers 20 EV charging spaces — the only verified off-site lot near IAH with confirmed EV infrastructure (verified June 2026). EV drivers who use multiple networks should also check the ChargePoint app for EV drivers to confirm compatibility before arrival. Demand for EV spaces at IAH is growing, so arriving with a reservation at a lot that confirms EV availability is the safest approach.

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

IAH on-airport valet parking costs $30/day — the most expensive option at the airport. You pull up to the terminal, hand your keys to an attendant, and your car is parked for you. Pick-up works in reverse: you call ahead and your car is waiting at the curb. There is no shuttle, no garage walk, and no searching for your car. For a deep look at the process, including drop-off locations by terminal and reservation tips, see our guide to George Bush Intercontinental Airport valet parking rates and how it works.

Is it worth the premium? For a one- or two-day trip, the gap between valet ($30/day) and the terminal garage ($25/day max) is only $5/day. The convenience may be worth it. For a 7-day trip, valet costs $210 total — compared to $27.93 at PreFlight's pre-book rate. That is an $182 difference. Most travelers on longer trips will find the off-site lots offer a better balance of price and service.

Tips for Finding the Cheapest IAH Airport Parking

A few straightforward moves will cut your IAH car parking rates significantly, based on our analysis of available options.

1. Book in advance: Pre-booking online (at fly2houston.com for on-airport, or through Triply for off-site) locks in lower rates. Drive-up pricing is always higher.
2. Use the ecopark for on-airport economy: At ~$6.47/day, the ecopark uncovered lot beats the terminal garage by almost $19/day.
3. Go off-site for trips of 3+ days: The off-site lots — especially PreFlight and Fine Airport Parking — deliver the best value once you factor in the free shuttle.
4. Look for 7-day rates: PreFlight drops to $3.99/day uncovered on a weekly booking. That is the cheapest verified IAH parking rate available (verified June 2026).
5. Enroll in loyalty programs: The Parking Spot's Spot Club Rewards earns points toward free parking days. Fine Airport Parking also offers perks for repeat customers.
6. Check coupon codes before booking: Discount codes can stack on top of pre-book rates. See our Bush Airport parking coupon guide for current deals.
7. Plan for construction delays: Terminal B's ticketing lobby is closed through late 2026. Allow extra time if you fly United from Terminal B, since you must check in at Terminal C and ride the Skyway. This affects how early you need to park.
8. Check traffic before you leave: Houston traffic on I-69 and Beltway 8 can be severe. Use the Waze live traffic map to time your drive and avoid missing your shuttle window.
