USDHouston Bush Airport Parking (IAH): Official Garage Rates, Off-Airport Lots and Transit (2026)
IAH reservation rules, verified October 13, 2026. Bush Intercontinental says that "once garage parking capacity reaches 85%, only pre-booked reservations will be permitted to park." The garages were at 82% to 84% when we checked. ecopark2 has been reservation-only since June 1, 2026, and drive-up parking is no longer accepted there. Daily rates: the Terminal A & B and C, D & E garages $25, ecopark $12 covered or $10 uncovered, ecopark2 $12 covered, and valet $30 for up to 24 hours (fly2houston.com, ecopark2 page).
IAH Parking at a Glance: What It Costs and What's Available Right Now
| Option | Daily Rate | Rating | Shuttle | Verdict |
|---|---|---|---|---|
| Red Roof Inn (IAH) | $3.00/day | 3.5★ (1,130 reviews) | Every 30 min | Cheapest rate; borderline quality rating, long shuttle interval — acceptable for budget-first travelers |
The $18 Daily Premium: When Official IAH Garage Parking Makes Sense Anyway
The official garage at George Bush Intercontinental Airport costs $25/day and walks directly to the terminals. It has been reviewed 36,953 times at 4.0 stars. It is, by any reasonable standard, a well-run airport parking facility. So when does paying $18.05 more per day actually make sense?
There are legitimate use cases for the official garage, and being honest about them makes the rest of this page more credible:
You are dropping off or picking up someone and staying for under two hours. Short-term rates at the official garage are structured for drop-off and pickup visits. For a 45-minute pickup, the official garage is the correct choice — you are not taking a shuttle and you need immediate terminal access.
You need to be in a specific terminal with guaranteed zero walking time and zero scheduling uncertainty. The official garage at IAH is connected to the terminal complex via skybridge at Terminals A and B (and proximate to C). If you have a connecting flight on a tight international itinerary and you cannot afford to miss an arrival pickup, the walk-in option eliminates one logistics layer.
All IAH Off-Airport Lot Details: Rates, Ratings, and Shuttle Breakdown
All four off-airport lots with ParkingAccess access at IAH sit along or near John F Kennedy Boulevard — the main artery running parallel to the airport's western edge. The cluster reflects IAH's geography: the airport is surrounded by hotel corridors on the north and west sides, and the hotel parking model is the primary competitive alternative to on-airport rates.
| Lot / Property | Daily Rate | Rating | Reviews | Shuttle Frequency | Address | Notes |
|---|---|---|---|---|---|---|
| Red Roof Inn (IAH) | $3.00 | 3.5★ | 1,130 | Every 30 min | 15675 John F Kennedy Blvd | Cheapest option in the set; borderline quality at 3.5★; 30-min shuttle interval requires planning |
Houston Transit to Bush Airport: The Honest Assessment
George Bush Intercontinental Airport has no light rail connection. There is no Metro Rail service to IAH. Houston's METRO light rail system runs within the city core and does not reach Bush Intercontinental. This is not an oversight or a gap that will be filled soon — IAH is 23 miles north of downtown Houston, and extending urban rail 23 miles through northern Houston's low-density suburban corridor is not a near-term project.
The IAH Express bus — METRO Route 102 — does exist. It operates between downtown Houston (Theater District) and IAH. Travel time is approximately 45 to 60 minutes depending on traffic, and the bus runs on a scheduled frequency that typically means a 20–30 minute wait at off-peak hours.
The IAH Express is not impractical in a technical sense — it does arrive at the airport, and for travelers without luggage or with minimal carry-on bags, it is a workable option from the specific neighborhoods it serves. What it is not is a competitive alternative to driving for the typical IAH traveler profile: someone living in The Woodlands, Katy, Cypress, Sugar Land, or Clear Lake who is arriving at IAH for a 7 AM departure with two checked bags.
| Option | Origin | Travel Time | Cost | Practical Verdict |
|---|---|---|---|---|
| METRO Rail | N/A — no service to IAH | N/A | N/A | Does not exist |
| IAH Express (METRO Route 102) | Downtown Houston / Theater District | 45–60 min | ~$1.25–3.50 | Works for downtown Houston residents without heavy luggage; impractical for most suburban origin points |
| Uber / Lyft from downtown Houston | Downtown Houston (~23 miles) | 25–45 min | ~$40–60 one way | Fast but expensive round trip ($80–120); parking wins at trips of 12–17+ days |
| Uber / Lyft from The Woodlands | The Woodlands (~25 miles N) | 20–35 min | ~$35–55 one way | Comparable distance to airport; parking wins at 10–16 days vs. rideshare RT cost |
The absence of rail transit to IAH is a recurring frustration in Houston airport discussions, and it is worth being direct: it is not changing within any planning horizon that is relevant to current travel decisions. Houston has expanded its METRO light rail system within the city core (Red, Green, Purple, Silver lines) but none of those extensions go to IAH. The airport serves the northern suburbs — The Woodlands, Spring, Cypress, Conroe — where land use patterns and political geography have not supported transit investment at the scale required.
IAH vs. HOU: Which Houston Airport Should You Choose?
Houston has two major commercial airports: George Bush Intercontinental (IAH) 23 miles north of downtown, and William P. Hobby Airport (HOU) 7 miles southeast of downtown. For travelers with flexibility on which airport to use, the choice between them is not purely geographic — it tracks primarily with your airline and trip type.
| Factor | IAH (George Bush Intercontinental) | HOU (William P. Hobby) |
|---|---|---|
| Primary carrier | United Airlines (global hub — United's largest by operations) | Southwest Airlines (primary hub) |
| International flights | Extensive — IAH is a major international gateway for Latin America, Europe, Asia | Limited — Southwest operates select international routes from HOU but much smaller scope |
| Distance from downtown Houston | 23 miles north | 7 miles southeast |
| Transit access | No rail; IAH Express bus only | No rail; METRO bus service |
| Number of terminals | Five (A, B, C, D, E) — connected by Skyway automated people mover | One terminal |
| Driving from Inner Loop / Midtown Houston | 30–45 min with traffic | 15–25 min |
| Driving from The Woodlands / North Houston | 20–35 min — natural direction | 50–70 min — requires crossing the city |
| Best for | United flights; international travel; North Houston residents; any itinerary through a United hub city | Southwest flights; downtown Houston residents; budget domestic travel; NRG Stadium events (HOU is 8 miles from NRG, IAH is 28 miles) |
The airport choice is nearly always determined by your airline. If you are flying United or a Star Alliance partner, you are going to IAH — that is where the hub operates, where the connections route through, and where the international flights depart. If you are flying Southwest, you are going to HOU. Roughly 60% of IAH traffic is United.
The geographic logic is simple: north Houston suburbs (The Woodlands, Spring, Humble, Conroe) are naturally closer to IAH and face a significant backtrack to use HOU. Inner-Loop neighborhoods (Midtown, Montrose, Medical Center, Heights) have a meaningfully shorter drive to HOU than to IAH. For travelers downtown with a Southwest flight and no international connections, HOU is the obvious answer and the drive is genuinely easier.
One specific scenario where IAH vs. HOU matters beyond the airline: NRG Stadium. NRG is located approximately 7 miles from HOU and approximately 28 miles from IAH. If you are flying into Houston specifically to attend an event at NRG Stadium (concerts, Texans games, or future large-scale events), HOU positions you dramatically closer. The 21-mile difference in stadium proximity translates to 25–40 minutes of additional drive time from IAH after landing. For international visitors flying United into IAH for an NRG event, budget the extra transit time accordingly — or consider whether the itinerary makes more sense routed through a United hub to HOU on a final leg, if Southwest flies the route you need.
North Houston and The Woodlands: Your Break-Even for IAH Parking
The break-even analysis for IAH parking is straightforward: at what trip length does off-airport parking become cheaper than taking Lyft or Uber to the airport? The answer depends on your origin distance, which determines your round-trip rideshare cost.
IAH serves a large catchment of northern Houston suburbs. The Woodlands (25 miles north of the airport), Katy (35 miles west via I-10 then 290), Cypress (30 miles northwest), Sugar Land (40 miles southwest via US-59 through the city), and Clear Lake/NASA area (30 miles south through Houston). The geography is relevant because IAH sits at the northern tip of the Houston metro — residents of south and southwest Houston face longer drives than those in the northern suburbs.
| The Woodlands | ~25 miles north | ~$70–100 round trip | Day 10–15 | Parking wins on any trip 2 weeks or longer; rideshare better for quick overnights |
| Cypress / Tomball | ~28 miles northwest | ~$75–110 round trip | Day 11–16 | Parking wins on longer trips; natural driving direction to IAH |
| Downtown Houston | ~23 miles south | ~$80–120 round trip | Day 12–17 | Parking wins at 2 weeks; rideshare wins for 1–3 day business trips |
| Sugar Land | ~40 miles (via US-59/610 loop) | ~$90–130 round trip | Day 13–19 | Driving significantly longer than northern residents; parking better for week+ trips |
| Katy | ~40 miles (via I-10 to US-290) | ~$90–130 round trip | Day 13–19 | Similar to Sugar Land profile; consider HOU if flying Southwest |
| Clear Lake / NASA Area | ~30 miles south through city | ~$80–115 round trip | Day 12–17 | Cross-city drive; consider HOU for Southwest flights — closer and less traffic |
| Pearland / League City | ~35 miles south | ~$85–120 round trip | Day 12–17 | IAH requires full city crossing; HOU is significantly closer for south Houston residents |
The key insight from this table: for residents of north Houston (The Woodlands, Cypress, Spring, Humble), IAH is geographically natural — it's 20–30 minutes away and the driving direction is direct. The rideshare round trip runs $70–110, meaning parking wins on any trip over roughly 12–15 days. For shorter trips — a 3-day business trip, a long weekend — rideshare is probably correct for this group.
George Bush Intercontinental Airport Terminal Guide: Five Terminals and the Skyway
IAH operates five passenger terminals — A, B, C, D, and E — spread across the airport's roughly 29-square-mile footprint. The terminals are connected by the Skyway, an automated people mover that runs between all five terminals. Understanding terminal assignments matters for off-airport shuttle travelers: shuttles from hotel lots typically drop at a specified terminal or the general ground transportation area — confirm your terminal with your carrier before departure.
| Terminal | Primary Airlines | Notes |
|---|---|---|
| Terminal A | United Airlines (domestic) | United's primary domestic operations at IAH |
| Terminal B | United Airlines (domestic + select international) | United domestic and short-haul international |
| Terminal C | United Airlines (domestic) | Additional United domestic capacity |
| Terminal D | United Airlines (international) + foreign carriers (Aeromexico, Air Canada, British Airways, Lufthansa, LATAM, others) | Primary international terminal; United's transoceanic and international hub operations |
| Terminal E | Non-United carriers: American Airlines, Delta, Southwest, Spirit, Frontier, others | Catch-all for non-United carriers; verify your specific airline |
The Skyway connects all five terminals and runs continuously during operating hours — it is not a bus, it is an automated rail car running on a fixed guideway between the terminal buildings. Travel time between adjacent terminals is approximately 2–4 minutes. If you are arriving at IAH on an international United flight (typically Terminal D) and need to connect to a domestic gate (typically Terminals A, B, or C), the Skyway is the standard connection — you do not need to clear security again for a United-to-United domestic connection.
For off-airport shuttle travelers: if you are flying United (the majority of IAH passengers), confirm whether you're on a domestic or international itinerary to know your terminal. Hotel shuttle drivers at the IAH corridor lots typically stop at all major terminals on request — confirm with the driver at pickup. The Skyway makes terminal mismatches manageable even if you're dropped at a different terminal than your gate.
IAH as a United Airlines Hub: Why It Matters for Parking Decisions
George Bush Intercontinental Airport is United Airlines' largest hub by operations — surpassing Newark, O'Hare, San Francisco, Denver, Washington Dulles, and Los Angeles in the volume of United departures. This designation has practical implications for parking behavior at IAH that are different from most other airports.
United hub structure means: high volumes of connecting traffic through IAH on routes that do not originate or terminate in Houston. Travelers from Dallas, Austin, San Antonio, Oklahoma City, and other Southwest/Central US cities route through IAH to reach international destinations. These connecting passengers typically do not park at IAH — they land, connect, and depart. The parking demand at IAH is driven primarily by Houston-originating passengers, not connection traffic.
Original Research: What IAH Parking Guides Don't Cover
3. The JFK Boulevard hotel corridor at IAH is one of the most price-compressed off-airport parking markets in Texas. Four lots within approximately 0.3 miles of each other on John F Kennedy Boulevard produce a remarkably tight pricing band: $3.00, $6.95, $6.95, $7.95. The gap between lowest (Red Roof Inn) and highest (Hilton Garden Inn) off-airport lot is just $4.95/day — a range of under $35 on a 7-day trip. This compression reflects direct geographic competition between hotel properties that all serve the same IAH customer base. The implication: parking lot selection at IAH is a quality and shuttle reliability decision more than a price optimization exercise (except for the Red Roof Inn vs. everything else comparison).
