Frontier Airlines passengers were stranded overnight in Knoxville after severe weather conditions forced their flight to make an unscheduled diversion to the airport.

According to reporting by Simple Flying on September 13, 2026, the diversion occurred after severe weather forced the aircraft to land in Knoxville.

Following the flight's arrival in Knoxville, the flight crew reached its legal duty limit, which prohibited the crew from continuing the flight.

Due to the combination of the weather diversion and the crew reaching its legal duty limit, the passengers remained stranded in Knoxville overnight.
