What are the top ATW airport security tips?

These tips are specific to Appleton (ATW) and verified against current airport configuration:

• ATW has a single, centrally located TSA checkpoint serving the entire terminal — there is no choice of checkpoint, and gates fan out to either side of it after screening.
• The checkpoint opens at 4 AM or two hours before the first scheduled morning flight, whichever is later — don't arrive earlier expecting it to be open.
• TSA PreCheck has a dedicated lane at ATW, but there is no CLEAR biometric lane at this airport (CLEAR enrollment events are occasionally held here, but standing CLEAR lanes are not in operation).
• Because ATW is a small single-concourse airport, the security line 'moves swiftly' outside of the first morning bank — arriving the standard 90 minutes before departure is normally enough.
• TSA Cares Passenger Support Specialists are available for travelers needing extra assistance — call 1-855-787-2227 at least 72 hours ahead to arrange it at this checkpoint.

Does ATW have TSA PreCheck?

Yes — ATW 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 ATW 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 ATW.

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