DENVER — Engine trouble forced a Frontier Airlines plane to return to Denver International Airport on Sunday.
Frontier spokesman Steve Snyder said the Las Vegas-bound plane carrying about 126 passengers landed safely and no one was injured.
Flight 765 was canceled as was the return Las Vegas-to-Denver flight.
Snyder said the airline was trying to get passengers on other flights.
Officials hadn’t determined what caused the problem in one engine.
