Smoke appeared in the cabin of an Allegiant Air plane just eight minutes after takeoff Monday afternoon, forcing pilots to return to St. Pete-Clearwater International Airport for an emergency landing.
Twenty-four minutes after the 4:28 p.m. takeoff, passengers on flight 864 were evacuated on emergency slides, the airline said in a statement.
Passengers then were bused to the terminal, airport spokeswoman Yvette Aehle said.
Three passengers and one flight attendant had reported injuries to Allegiant as of 7 p.m., according to the airline. The airline said it had no reports of anyone being taken to the hospital or treated on scene.
All 141 passengers will receive vouchers for $200 and a full refund for the flight to Hagerstown Regional Airport in Maryland, which Allegiant has rescheduled for Tuesday afternoon.
The airline said it will provide hotels for passengers who don't live in the area.
