Alaska Airlines Flight 139 took off from Chicago bound for Ted Stevens Anchorage International Airport.
The flight was instead re-routed to Joint Base Elmendorf-Richardson around 1:30 p.m., a spokesperson for the base said.
Apparently behind the crosstown landing are hazy weather conditions that have blanketed Southcentral Alaska for days, though it is not immediately apparent why it was easier to land at the East Anchorage base than at the state's airport.
National Transportation Safety Board spokesperson Clint Johnson said the flight is one of two diverted today due to poor visibility.
In addition to the flight that landed at JBER, another went to Fairbanks, he said.
Alaska Airlines spokesperson Marilyn Romano said the plane is still grounded at JBER, but the passengers are being shuttled to Ted Stevens in buses.
