How Does the Terminal B Lobby Closure Affect Parking and Check-In?

This is the most important thing Terminal B travelers need to know in 2026. The Terminal B ticketing lobby closed in January 2025 as part of United Airlines' $2.6 billion Terminal B expansion — the largest single-airline terminal project in the United States. The closure runs through late 2026. All Terminal B passengers must now check in at Terminal C, then take the free Skyway people mover or the Subway underground train to reach Terminal B gates.

Terminal B ticketing is closed through late 2026. Check in at Terminal C, then connect to Terminal B via the free Skyway or Subway. Allow at least 20–30 extra minutes. (Source: Houston Airport System, verified June 2026)

Here's how this changes your parking-to-gate flow:

1. Park in the Terminal A/B Garage or an off-site lot with shuttle service.
2. Walk or take the Skyway to Terminal C for United Airlines check-in.
3. Clear security at Terminal C (allow extra time — more passengers are using this checkpoint now).
4. Take the Skyway (inside security, above ground) to Terminal B gates.

The Skyway runs 24/7 and connects all five terminals inside security. The Subway also runs 24/7 but operates outside security — so use the Skyway once you've cleared TSA. Make sure to review TSA security screening guidelines before you arrive, especially with the added checkpoint traffic at Terminal C during this construction period.

If you have TSA PreCheck, this detour is far less stressful. PreCheck lanes move significantly faster at Terminal C, and you'll clear security in a fraction of the time. Build in at least 20–30 extra minutes compared to your normal pre-flight routine.

How Do You Get to the Terminal B Parking Garage at IAH?

The Terminal A/B Garage sits directly off John F. Kennedy Boulevard, the main airport access road at IAH. The fastest routes from Houston's major highways are straightforward once you know the exits.

From Interstate 69 / US-59 (Eastex Freeway)

• Take the Will Clayton Parkway exit heading west toward IAH.
• Follow Will Clayton Parkway to John F. Kennedy Boulevard and turn south.
• Follow airport signs for Terminal A/B parking on your right.

Houston traffic on I-69 and Beltway 8 can be heavy, especially during morning and evening rush hours. Before you leave, check real-time traffic on Waze to pick the fastest route. IAH is 23 miles north of downtown Houston — that translates to anywhere from 25 to 40 minutes depending on traffic conditions.

Once inside the Terminal A/B Garage, follow color-coded signs to your level. The garage uses a green and purple color-coding system by zone to help you remember where you parked. Take a photo of your zone, level, and space number before walking away.
