The Ninoy Aquino International Airport has been ranked the fifth worst airport in Asia, according to a travel website.

The travel website The Guide To Sleeping In Airports said complaints against NAIA include the 'tanim bala' scam (an extortion scheme that dupes passengers by putting a bullet in their baggage), power outages, bad air conditioning system, lack of seats, and complicated terminal transfers.

Despite these shortcomings, the website acknowledges improvements in Manila's main gateway, saying survey responders took note of "cleaner bathrooms, more chairs and some general organization of taxis in front of the terminal would help to make life here a lot more manageable."

Topping the list of the worst airports in Asia is Uzbekistan's Tashkent International Airport, followed by Nepal's Tribhuvan International Airport, Pakistan's Bacha Khan International Airport, and Afghanistan's Hamid Karzai International Airport.

Trailing NAIA on the list are Pakistan's Benazir Bhutto International Airport, India's Chennai International Airport, China's Guangzhou Baiyun International Airport, Bangladesh's Shahjalal International Airport, and Cambodia's Siem Reap International Airport.

NAIA was ranked the world's worst airport in 2011 and 2013, and was also named worst in Asia in 2012.

Last year marked the first time NAIA did not make it to the world's worst airports, though it was still among the worst in Asia.

Meanwhile, 4 Philippine airports have made it to the website's Top 30 Best Airports in Asia. Iloilo International Airport was ranked 12th, Mactan-Cebu International Airport ranked 14th, Clark International Airport ranked 15th, and Davao City's Francisco Bangoy International Airport ranked 26th.
