The state Aeronautics Commission says Minot, Bismarck, Grand Forks and Fargo all had their best February on record.
The Williston airport saw a jump in boardings over the year of 138 percent and had its best month for boardings in history.
Fargo had the biggest jump in actual boardings, with an increase over the year of just under 2,000 passengers. The increase statewide was about 8,800, or more than 10 percent.
Aeronautics Commissioner Larry Taborsky says airlines have responded to the demand by increasing the number of flights.
