Ketchikan public safety officials say the plane with 135 passengers on board landed safely Monday morning.
Ketchikan Public Safety Director Rich Leipfert said the fire department received a call from the airport regarding a flight that had reported an in-flight emergency having to do with a fuel transfer problem.
Alaska Airlines spokeswoman Caroline Boren said Flight 118 landed in Ketchikan with a "mechanical issue."
Boren told the Ketchikan Daily News on Monday that additional details weren't immediately available, and could not confirm a fuel transfer problem.
Boren did not immediately return a message left Tuesday by The Associated Press. Another Alaska Airlines jet was sent to Ketchikan to continue the flight.
