BISMARCK, N.D. (AP) – Passenger boardings at North Dakota’s eight commercial airports in 2013 set a record for the second straight year.

The state Aeronautics Commission says boardings in Fargo, Bismarck, Grand Forks, Minot, Williston, Dickinson, Devils Lake and Jamestown totaled more than 1.1 million. That was an 11 percent increase from 2012, when boardings surpassed the million mark for the first time.

North Dakota has a healthy economy in large part because of an oil boom in the western part of the state. Passenger boardings in the oil patch cities of Dickinson and Williston were up 47 percent and 152 percent respectively over the year.

Aeronautics Commissioner Kyle Wanner says he expects the growth to continue.

In December, of 2013 Jamestown boardings were 214, compared to 300 in December of 2012.
