MANILA - The Ninoy Aquino International Airport has fallen out of the list of Asia's worst air terminals, according to travel website Sleeping in Airports.

At the same time, it ranked 4 Philippine terminals among Asia's 25 best for 2017: Iloilo International Airport (12th), Mactan–Cebu International Airport (13th), Davao Francisco Bangoy International Airport (17th) and Clark International Airport (22nd).

Seoul Incheon International Airport in South Korea, Tokyo Haneda International Airport in Japan, Hong Kong International Airport, Hong Kong and Tokyo Narita International Airport in Japan
