Oman Air (WY, Muscat) and Jet Airways (Mumbai International) have both been denied rights to Manila Ninoy Aquino International by the Philippine Civil Aeronautics Board (CAB) as a result of growing congestion at the airport. According to a CAB official, the two carriers had applied for landing slots between 07h00 and 19h00, the busiest time of the day for the airport. The possibility of using other airports in the country was ruled out as "most were not night rated and are limited to day time operations." Oman Air has stated that it will cooperate with Manila in finding a solution to the problem. With NAIA became the 34th busiest airport in the world in 2012 with passenger volumes reaching a record total of 32.1 million, Filipino Transportation Secretary, Joseph Emilio Abaya, said he hoped to address the issue of congestion by agreeing to a co-development scheme for NAIA and Angeles City Clark International, located some 100 kilometers north of the capital in which both would be upgraded.
