What are the top GPI airport security tips?

These tips are specific to Kalispell (GPI) and verified against current airport configuration:

• GPI has a single security checkpoint serving all 6 gates — there is no choice of checkpoint, but it was rebuilt as part of the 2024 Phase 1A terminal renovation with new hold rooms and a modernized screening area.
• A dedicated TSA PreCheck lane has been available at GPI since 2018; there is no CLEAR service at this airport.
• Typical wait is well under 15 minutes off-peak, but summer tourist season (June–September) into Glacier National Park can push waits to 30-45 minutes during peak banks — arrive at least 2 hours before departure in summer.
• GPI's Visitor Pass program lets non-ticketed guests pass through the checkpoint to accompany travelers or use post-security amenities; the checkpoint for visitor-pass holders opens 2 hours before each departure and closes once that flight departs.
• Because the terminal is small and compact, security-to-gate walk time is only a few minutes — you don't need the padding at GPI that you would at a large hub, aside from the line itself.

Does GPI have TSA PreCheck?

Yes — GPI 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 GPI 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 GPI.

GPI 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 GPI PreCheck lanes. Details on Global Entry at GPI.
