Allegiant Air, based in Las Vegas, is already shuffling some of its small-city routes.
An Associated Press story today noted that Allegiant is cancelling flights between Sioux Falls, S.D., and LA, citing lack of space at LA International Airprot.
Also being shut down are Allegiant flights to LA from Billings and Pasco.
An Allegiant spokesman said the airline lacks adequate gate and ticket counters at LAX.
The low-cost airline announced this week it's launching flights in January between Spokane and Honolulu.
