Flight 2874 was headed to Bangor, Maine but looped around after developing some sort of in-flight issue.
An airline spokesperson said the plane “returned to field shortly after takeoff to address a maintenance issue. No emergency was declared.”
Passengers were being loaded onto another plane to complete the trip.
This is the latest of several incidents for Allegiant. The airline delayed and canceled flights nationwide last week, while passengers were forced to evacuate from one of their planes after landing in Clearwater a month ago.
