How Much Does George Bush Intercontinental Airport Parking Terminal A Cost in 2026?

The Terminal A/B Garage charges $5 per hour, with a $25 maximum per day, per official Houston Airport System published rates (verified June 2026). That daily cap resets on a calendar-day basis, not a rolling 24-hour cycle — so an overnight stay spanning two calendar days counts as two days.

Here's a quick breakdown of all on-airport options at IAH:

For a 3-day trip, the Terminal A/B Garage costs $75 total. The ecopark uncovered option runs roughly $19.41 for the same period — a savings of over $55. Pre-booking online at fly2houston.com unlocks discounted rates on ecopark and other on-airport options. For a full breakdown of long-term costs, the IAH long-term parking rates guide covers weekly and extended-stay pricing in detail.

How Do You Get to Terminal A Parking at IAH?

The Terminal A/B Garage sits directly adjacent to Terminals A and B. It's the most convenient on-airport parking option for Terminal A travelers.

Driving to the Terminal A/B Garage

Take John F. Kennedy Boulevard (JFK Blvd) as your main approach road into IAH. From the Sam Houston Tollway (Beltway 8), exit onto JFK Blvd and follow airport signage toward Terminals A and B. The garage entrance is clearly marked. Before you leave home, check real-time traffic on Waze — Houston traffic on I-69/US-59 and Beltway 8 can add 15-30 minutes during peak hours.

Walking from the Garage to Your Gate

Once parked, the walk from the Terminal A/B Garage to the Terminal A check-in hall is short — typically under 5 minutes on foot. Accessible parking spaces are located on the ground floor of the garage. Van-accessible spaces are available as well.

Connecting to Other Terminals

IAH runs two free inter-terminal connections: the Skyway (automated people mover, above ground, inside security) and the Subway (underground train, outside security). Both operate 24/7. If your itinerary involves any Terminal B check-in — note that Terminal B's ticketing lobby is closed through late 2026 due to the $2.6 billion United Airlines Terminal B expansion. All Terminal B passengers must check in at Terminal C and take the Skyway to their gates. Plan extra time if this affects a connection.

What Are the Best Off-Site Parking Alternatives Near Terminal A?

Off-site lots near IAH offer the biggest savings for Terminal A travelers, especially on trips of three days or longer. Based on current Triply rates, all six verified off-site lots run free 24/7 shuttle service to all IAH terminals, including Terminal A.

Fine Airport Parking runs the most frequent shuttle at every 5-7 minutes — the best pick if you're tight on time. PreFlight Airport Parking offers the lowest rate at $3.99/day on 7-day bookings, making it ideal for longer trips. All lots listed above offer free cancellation, so booking early carries no risk. For travelers who want covered parking off-site, our guide to IAH airport parking covered options compares covered lots in detail.

Terminal A On-Site Parking vs. Off-Site Lots: Which Should You Choose?

The right choice depends on your trip length, budget, and how much walking you're comfortable with.

• Terminal A/B Garage (on-site): Best for short trips of 1-2 days. Walk to check-in in under 5 minutes. No shuttle wait. Costs $25/day maximum.
• ecopark (on-site economy): Good middle ground. Costs ~$6.47/day uncovered or ~$8.31/day covered. Free shuttle every 10-15 minutes. Add 15-20 minutes to your airport arrival time.
• Off-site lots: Best value for trips of 3+ days. Rates from $6.63/day with free shuttles. Save up to 73% versus the garage daily cap. Shuttle adds roughly 10-20 minutes each way.
• Valet parking: Most convenient but priciest at $30/day. Drop your car at the curb and go. Best for travelers with heavy luggage, young children, or early morning flights.

For a 5-day trip, the Terminal A/B Garage costs $125. PreFlight Airport Parking's 7-day uncovered rate works out to roughly $20 for the same period — a difference of over $100. Families with strollers or travelers carrying oversized bags often find the valet or garage most practical despite the higher price. If you're traveling solo or as a couple with manageable luggage, off-site is hard to beat on value.

How Do You Reserve George Bush Intercontinental Airport Parking Terminal A in Advance?

Booking ahead saves money and guarantees a spot — especially during holiday weekends and summer peak travel. IAH's ~40,000 total parking spaces fill quickly during Thanksgiving, spring break, and major Houston events (per Houston Airport System data).
