The Development, Operation and Maintenance of Laguindingan Airport is set to be signed in May 2015.
This is based on an indicative timeline disclosed during the PPP Roadshow by the government. Among the major development of the airport once the O&M is privatized to the winning bidder are: expansion of passenger terminal building, extension of runway, expansion of cargo terminal building, apron expansion and a full length parallel taxiway (3.5 km).
