Which MFE security checkpoint is fastest?

MFE operates a single main checkpoint, so all passengers enter the same security lane. TSA PreCheck is the primary tool for faster throughput here — members keep shoes, belts, and laptops packed.

CLEAR is not currently available at MFE. TSA PreCheck at MFE remains the best single upgrade for reducing your security wait.

What are the top MFE airport security tips?

These tips are specific to McAllen (MFE) and verified against current airport configuration:

• MFE has a single unified TSA checkpoint serving all six gates — there's no choice of checkpoint, but the compact terminal means the walk from checkpoint to any gate takes only a few minutes.
• TSA PreCheck lanes are available at the checkpoint; MFE is neither a Global Entry enrollment center nor a CLEAR location, so enroll before you travel if you want expedited screening (the nearest CLEAR/Global Entry centers are in San Antonio or Houston).
• The airport is currently running over capacity for its six gates amid a passenger-growth surge (1.2M+ travelers in 2024) and a planned $178–180M, four-gate expansion — arrive with extra buffer, since a full flight bank can bottleneck the single checkpoint and concourse.
• If you have TSA PreCheck or are traveling with family/mobility needs, tell the checkpoint officer directly — MFE doesn't have a separately signed family lane, but officers can accommodate you within the one checkpoint.
• International departures to Mexico (Aeromexico, Volaris, Aerus) go through the same single domestic-style checkpoint — MFE has no separate international departure security area, only a Federal Inspection Station for arriving international passengers on the arrivals side.

Does MFE have TSA PreCheck?

Yes — MFE 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 MFE 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 MFE.

MFE does not host a Global Entry enrollment center or Enrollment on Arrival, so the interview has to be completed at another location — but membership still pays off here, since Global Entry includes TSA PreCheck for the MFE PreCheck lanes. Details on Global Entry at MFE.
