Four North Dakota airports set records for passenger boardings in July.
The state Aeronautics Commission says Dickinson and Williston in the western oil patch got a boost from additional flights and set records.
Dickinson had an 84 percent jump over the year and Williston a 220 percent jump.
The Fargo and Grand Forks airports both had their best July on record.
Overall, the state's eight large airports saw an over-the-year increase in boardings of 13 percent.
Aeronautics Commissioner Larry Taborsky says the number of passengers flying from North Dakota airports is now double what it was 10 years ago.
