What are the top HOU airport security tips?

These tips are specific to Houston (HOU) and verified against current airport configuration:

• HOU is Southwest Airlines' original home base, operating from a single terminal with two main security checkpoints feeding five concourses.
• CLEAR is not available at HOU; PreCheck is offered at both checkpoints and is consistently well-staffed.
• HOU is Houston's short-haul leisure airport; Monday mornings and Friday evenings are the peak congestion windows.
• Southwest's open seating model drives some passengers to arrive very early to secure boarding position, compressing the pre-security queue — a 90-minute lead can catch a surge.
• The airport has easy highway access from I-45 and Loop 610; rideshare drop-offs are efficient from the departure level.

Does HOU have TSA PreCheck?

Yes — HOU has TSA PreCheck lanes at its security checkpoints. PreCheck members keep shoes, belts, light jackets, laptops, and 3-1-1 liquids packed, and pass through a dedicated screening lane. Membership costs $85–$100 for five years and includes a Known Traveler Number (KTN) you add to every booking.

See live PreCheck wait times and current lane status on the HOU TSA PreCheck page. That page also covers which terminals have a PreCheck lane, enrollment locations, and how PreCheck compares to CLEAR and Global Entry at HOU.

Global Entry interviews can be completed at HOU itself — via an on-site enrollment center or Enrollment on Arrival after an international flight — and membership includes TSA PreCheck. See Global Entry at HOU for locations and hours.
