LAS VEGAS — Allegiant Air officials say a Bellingham-bound plane having engine problems turned around and returned to Las Vegas on Sunday night.

Allegiant spokesman Justin Ralenkotter says Flight 225 to Bellingham departed McCarran International Airport at 7:10 p.m. Sunday before crew members noticed an oil temperature problem in one of the plane’s two engines.

The MD-80 aircraft arrived back in Las Vegas at 7:48 p.m.

Ralenkotter says passengers hadn’t reported problems during the short ride, and the plane is designed to continue operating on a single engine.
