Houston Intercontinental (IAH) Airport Parking Guide 2026

George Bush Intercontinental (IAH) is Houston’s largest airport, United Airlines’ biggest hub anywhere in the world, and one of the busiest US airports for international travel. It serves around 46 million passengers a year through five terminals (A, B, C, D, and E) arranged around a central core, connected by the Skyway above-ground people mover and the TerminaLink underground train. Parking spans the full range: terminal-adjacent garages, two large “ecopark” economy lots with shuttle service, and a dense ring of off-airport lots along JFK Boulevard, Will Clayton Parkway, and the JFK-area service roads.

This guide covers every IAH parking option with current rate ranges, shows how the daily cost adds up over typical trip lengths, walks through Houston-specific considerations (hurricane season, Astros and Texans game traffic, business-travel peaks for the Texas Medical Center and oil & gas industry), and lays out the cheapest realistic ways to park at Bush Intercontinental in 2026.

Rates and lot names current at time of writing. Always confirm on the official IAH parking page before relying on them.

Terminals A through E & the Skyway

IAH’s five terminals are arranged in a roughly circular core, connected to each other by the free Skyway above-ground people mover and the TerminaLink underground train:

  • Terminal A — international and domestic flights for several non-United carriers.
  • Terminal B — United Express regional flights.
  • Terminal C — United mainline domestic and select international.
  • Terminal D — IAH’s primary international terminal (Mickey Leland International Terminal). Most non-United international flights operate here.
  • Terminal E — United mainline domestic and international.

Confirm your airline’s terminal before choosing parking. Each terminal has its own dedicated garage right next door — matching the terminal saves the most walking. For ecopark, ecopark2, and off-airport parking, the shuttle drops you at every terminal, so you don’t need to optimize lot choice for terminal.

Skyway tip: the Skyway runs above the terminal core every 3–4 minutes and is the fastest connection between terminals. Allow 15–20 minutes terminal-to-terminal when you factor in walking to and from Skyway stations.

IAH Parking Options Compared

IAH parking splits into three tiers, each balancing cost against convenience.

Option Distance to terminal Price tier
Terminal Garage (A, B, C, D, E) Walk to matching terminal Highest
ecopark / ecopark2 Free shuttle to terminals (typically 5–10 min) Mid (lowest official rate)
Off-airport (privately operated) 5–15 minute shuttle along JFK Blvd / Will Clayton Pkwy Lowest (with amenities)

For short trips and pickups, the matching terminal garage wins. For multi-day stays, ecopark or pre-booked off-airport almost always wins on total cost.

On-Airport Parking at IAH

IAH’s on-airport parking includes:

  • Terminal A, B, C, D, E Garages — each terminal has its own dedicated multilevel garage right next to ticketing/baggage claim. Best for pickups, drop-offs, short trips, or when matching your terminal exactly matters.
  • ecopark — the original on-airport economy surface lot, with a free shuttle to all terminals.
  • ecopark2 — a newer, slightly closer economy lot with similar pricing and shuttle service.
Heads up: ecopark and ecopark2 are operated by the airport with shuttle service that runs frequently but isn’t instant — build in 10–15 minutes for the shuttle on top of the walk to your terminal entrance.

ecopark and ecopark2

IAH’s “ecopark” lots are the airport’s answer to budget on-site parking. Key features:

  • Daily rates approximately $7–$10/day, often lower than off-airport for very short trips.
  • Free shuttle to all five terminals.
  • Operated by the Houston Airport System — official IAH parking with standard security, lighting, and patrols.
  • Two locations (ecopark and ecopark2) with similar pricing and shuttle service.

For travelers who prefer staying on official airport property but don’t want the terminal garage rate, ecopark or ecopark2 is the natural pick.

Off-Airport Parking Near IAH

Off-airport lots cluster along JFK Boulevard, Will Clayton Parkway, and surrounding service roads. They’re privately operated, run free shuttles to all five IAH terminals, and almost always beat the terminal garage rate when pre-booked online. Common features:

  • Daily rates from about $7/day pre-booked, with regular promos and multi-day discounts.
  • 24/7 shuttles running every 10–15 minutes (more frequently during peak hours).
  • Self-park and valet options at most lots.
  • Covered/indoor parking at some lots — useful during Houston summer heat, hailstorms, and hurricane season debris/wind events.
  • Online booking with date-locked rates and instant confirmation.

The trade-off: an extra 5–15 minutes for the shuttle ride. For multi-day Houston stays, the savings plus covered-parking value often justify the choice.

IAH Parking Rates

Approximate ranges as of 2026:

Lot type Typical daily rate Best for
Terminal Garage (any terminal) $25–$28 / day max Quick trips, pickups, business travel

Ranges are approximate. IAH rates change — verify on the official IAH site or at checkout on ParkON.

Total Cost by Trip Length

Approximate totals using mid-range rates:

Trip length Terminal Garage (~$26/day) ecopark (~$9/day) Off-airport (~$7/day)
1 day ~$26 ~$9 ~$7
3 days ~$78 ~$27 ~$21
5 days ~$130 ~$45 ~$35
7 days ~$182 ~$63 ~$49
14 days ~$364 ~$126 ~$98
Pattern: a week at a Terminal Garage costs ~$182. A week at ecopark or pre-booked off-airport runs $63–$49. That’s $100+ in savings on every multi-day trip — meaningful for frequent business travelers.

Hurricane Season & Severe Weather

Houston sits on the Gulf Coast and the airport region is subject to hurricane impact roughly June 1 through November 30. Severe storms can drive flight cancellations, IAH operational delays, and (rarely) full airport closures:

  • Pre-trip: check the National Hurricane Center forecast for any named storm in the Gulf within 5 days of your travel.
  • Choose covered parking during peak season (August-October), especially for multi-week trips — protection from wind-blown debris and hail.
  • Photograph your car before parking, with all sides and the odometer visible.
  • Verify the lot’s storm policy for flight cancellations, early returns, evacuation orders, and rebooking.
  • Keep your reservation accessible on your phone (not just your inbox) in case cell service is congested.
Storm-week rule: if a named storm is forecast to track within 100 miles of Houston during your trip, consider switching to off-airport parking with proven storm policies and a clear modification path — not a remote economy lot where service may be reduced.

Astros, Texans, Rodeo & OTC: Houston Peak Weeks

Houston’s civic calendar drives parking demand at IAH:

  • Houston Livestock Show & Rodeo (late February through March): three weeks of major attendance bring out-of-town visitors and performer travel.
  • Offshore Technology Conference (OTC, early May): the world’s largest oil & gas industry conference packs Houston hotels and IAH.
  • Astros playoff games (October): playoff series at Minute Maid Park bring nationwide travel.
  • Texans home weekends (fall): NRG Stadium home games bring regional arrivals.
  • Texas Medical Center business travel — year-round, but especially heavy on Sundays/Mondays as physicians and researchers travel for conferences.
  • Major holidays: Thanksgiving, Christmas/New Year, Memorial Day, July 4, Labor Day all run hot.
Peak-week rule: for any of the above, book your IAH parking 1–2 weeks in advance. The cheapest lots sell out first.

Getting to IAH

IAH is about 23 miles north of downtown Houston. Main highway accesses:

  • From downtown Houston / Midtown: Hardy Toll Road north (fastest), or US-59 (Eastex Freeway) north to Beltway 8 east.
  • From The Woodlands / Spring / Conroe: I-45 south to Beltway 8 east, or Hardy Toll Road south.
  • From Katy / West Houston: I-10 east to Beltway 8 north.
  • From Galveston / South Houston: I-45 north to Beltway 8 east.
  • From Sugar Land / Pearland: Sam Houston Tollway (Beltway 8) north directly to IAH.

Allow a generous buffer during Houston rush hour (6–9 AM and 3–7 PM weekdays) and on Astros, Texans, or major-event evenings — I-45, US-59, and Beltway 8 can all back up significantly.

How to Save on IAH Parking

  1. Pre-book online. Pre-booked rates beat drive-up at virtually every off-airport lot, and many on-airport options.
  2. Compare on-airport vs off-airport. The gap can be $15–$20/day on multi-day stays. Use ParkON to see options side by side.
  3. Use ecopark or ecopark2 for budget official parking. Free shuttle plus the lowest official rate.
  4. Off-airport for 4+ day trips. Savings scale with trip length.
  5. Book covered parking during summer and hurricane season. Houston heat, hailstorms, and tropical-system winds all favor it.
  6. Book early for Rodeo, OTC, Astros playoffs, Texans games, and holidays. The cheapest lots sell out first.
  7. For pickups under 30 minutes, use the free Cell Phone Lot. It’s the cheapest option for short pickups.
  8. For solo, short trips from inside Houston: compare a round-trip rideshare against parking. See our parking vs. rideshare guide.
