Airport officials are eyeing a second concourse to keep up with increasing customers and to entice more airlines and passengers.

The Northwest Arkansas Regional Airport Authority board recently gave staff approval to find a design firm for the addition, which would add up to 94,000 square feet to the terminal. Estimated cost is $72 million to design and build. Design, planning and engineering is estimated to cost about $3 million.

Officials think most of the cost could be paid through a mix of federal money the airport receives, airline rates and charges and some new revenue from concessions and other sources.
