MANILA -- The Philippines is surrounded by cities with international airports that regularly top lists of the world's best: Singapore, Hong Kong, Tokyo, Bangkok.
Then there is Manila's Ninoy Aquino International Airport, or NAIA. It has the unpleasant distinction of being named among the world's least desirable airports for its old facilities, over capacity and traffic congestion. In a ranking of the world's worst airports compiled by the website Sleeping in Airports, it topped the list in 2011 and 2013.
