How delays work at TYS

A ground stop holds flights bound for TYS at their origin airports. A ground delay program spaces arrivals out so the airport is not overloaded. Departure and arrival delay messages describe the average wait the FAA expects. None of these tell you whether your own flight is late, so always check your airline as well.

Local tips

  • Plan 2.5 to 3 hours at TYS, especially during the morning and late afternoon peaks.
  • Economy Lot C at $13 per day is the lowest-cost lot with a shuttle, while Terminal Lot A is the closest surface lot at $16.
  • Confirm hotel shuttle hours before booking. Tru by Hilton runs 5 a.m. to midnight, and La Quinta runs 7 a.m. to 11 p.m.
  • For an early flight, the Hilton Knoxville Airport is connected to the terminal by a covered walkway, so you can stay close to the terminal the night before.
  • Schedule Uber or Lyft rides in advance, since availability can be limited during off-peak hours.
