Airline boardings continue to climb at North Dakota's eight commercial and regional airports, the Associated Press reports.
Statewide, nearly 9,000 more passengers boarded airlines in February than the same month a year ago, according to the state Aeronautics Commission.
The Williston airport -- where the state's oil fields are spurring more activity -- saw the biggest jump in boardings with an increase of 138 percent. Minot, Bismarck, Grand Forks and Fargo also had their best February on record.
Carriers have responded to the demand by adding more flights. Delta Air Lines and United Airlines plan to offer additional service starting in June.
