MANILA, Philippines (The Adobo Chronicles) – From 2011 to 2013, Manila’s Ninoy Aquino International Airport (NAIA) topped the list of the world’s worst airports as compiled by an international travel website. Now, NAIA is desperate to regain that title and is doing all it can to make it happen.

Late last year, NAIA made headlines because of laglag bala (bullet drop), a scheme in which unscrupulous airport personnel plant live bullets into the luggage and bags of unsuspecting passengers for the purpose of extorting money.

The latest scheme, as reported by The Inquirer, is called laglag kisame (ceiling drop) in which portions of the airport’s passenger terminal ceiling collapse without warning.

The latest incident involved the collapse of a portion of the ceiling of a restaurant inside Terminal 3, causing injury to an American passenger, Day Adam Warner.

Similar mishaps happened inTerminal 2 in December 2012, where a Hong Kong-bound passenger was injured; and inTerminal 1 in February 2014. In addition, many passengers  have complained of leaking ceilings, collapsed floors, malfunctioning equipment, congestion, dilapidated facilities, rude or corrupt personnel and several airport taxi scams.

Following the latest incident, the U.S. State Department has issued a travel advisory asking American citizens flying in or out of NAIA to wear protective hard hats to ensure their safety while inside the airport terminal.
