Is customs clearance available at KTHA?
Tullahoma Regional / William Northern Field does not have customs onsite, based on the data on file.

What is the attendance schedule at Tullahoma Regional / William Northern Field?

Crews operating outside the attended window should plan accordingly, since staffing support is limited to the posted hours.
Does KTHA see seasonal traffic variation?

October recorded the highest monthly count at 151 operations, followed by August at 144 and June at 128, according to FAA TFMSC data for 2025. Winter months are comparatively quiet, with November and December each under 80 operations. Dispatchers scheduling flights into KTHA during peak months should anticipate higher local activity levels.
What wildlife or shared-use hazards should pilots expect at KTHA?
