LINCOLN, Neb. (AP) — Officials at the Lincoln Airport say passenger traffic is on pace to increase for the third consecutive year.

Airport officials announced Monday that passenger numbers on commercial airlines were up 15 percent through the first six months of 2015.

One reason for the increase is the addition of daily flights to Atlanta in September 2014. Delta Airlines agreed to offer the flights for one year, but airport Executive Director David Haring says the strong performance could encourage the airline to continue its service.
