Commercial passenger traffic at the Fort Smith Regional Airport was up 8.5% in July.

According to the airport's latest passenger traffic report, the number of people boarding flights went up from 8,319 in July 2018 to 9,030 last month.

Most of the enplanements, or people boarding flights, went through American Airlines to Dallas-Fort Worth. There were 6,731 enplanements for American Airlines at the Fort Smith airport last month. It was a 13 percent increase from the prior July.

Delta Air Lines saw a 4.5 percent decrease in enplanements at the Fort Smith airport to Atlanta last month. There were 2,409 passengers boarding flights with Delta to Atlanta in July 2018 and 2,299 last month.

Airport Director Michael Griffin said Tuesday a study is being conducted that will will determine an estimate on the number of passengers from the Fort Smith airport who  stay in the Dallas and Atlanta areas and how many continue to other destinations from each hub.

Griffin will present the findings to the Fort Smith Airport Commission once the study is completed in a couple months. Griffin has also worked to retain and grow the two current air carriers, and recruit new ones with commission support.

The commission budgets $25,000 annually for marketing air services at the airport. Griffin said it is not money used to attract carriers, but is for advertising when they start service. It can be used if American or Delta add a new destination as well, he explained. The costs of the air service study and Griffin's attendance to air service conferences for meetings with airlines comes from other airport accounts.
