Philippine Airlines (PR, Manila Ninoy Aquino International) along with Zest Air (Manila Ninoy Aquino International), Cebu Pacific Air (5J, Manila Ninoy Aquino International) and PAL Express (2P, Manila Ninoy Aquino International) have all expressed their displeasure at the Philippine Department of Transportation and Communications' decision to forge ahead with the June 15 opening of the new USD190million Laguindingan International Airport, set to replace the smaller Cagayan de Oro Laguindingan airport as the gateway to the northern Mindanao and Misamis Oriental provinces. According to the PhilippineFlightNetwork blog, the carriers had originally succeeded in pushing back the original launch date of April 30 to June by asking the Civil Aviation Authority of the Philippines to delay the transfer of flights until after the summer season in order "to minimize disruption to passengers and to permit more time to rearrange flight schedules". The airlines also complained that "they were experiencing difficulties in communicating changes to passengers who had bought their tickets for flights in April and May". In addition, locals in Cagayan de Oro are not convinced the airport is ready following revelations that its infrastructure is not up to scratch. Among the shortcomings are navigational aides, necessary for night flights, that will only be installed by the CAAP in late 2014, as well as a critical shortage of electrical power needed to adequately run the airport's facilities.
