World's 10 worst airport terminals have finally been revealed in a new survey. Last year, Ninoy Aquino international airport of Manila, Philippines ranked at number one. Now, the Manila airport has been replaced by Islamabad. What other airports made it to the world's 10 worst airport terminals?

Manila's airport had been named one of the world's 10 worst airport terminals due to its congestion and defective luggage terminals. The results had been done via a survey on Guide to Sleeping in Airports. Apart from congestion and the terminals, tourists had added that "overcrowding, lengthy queues, limited seating, unfriendly immigration/customs officers and smelly toilets" made the Manila airport number one in the world's 10 worst airport terminals.

Yet, the Manila airport seems to have ranked relatively lower this year on the 2014 edition of world's 10 worst airport terminals. Ninoy Aquino international airport ranked at number four this year. The latest survey done by Guide to Sleeping in Airports now names Islamabad Benazir Bhutto international airport of Pakistan as number one of the world's worst. The world's 10 worst airport terminals is as follows:

1. Islamabad Benazir Bhutto international airport, Pakistan (ISB)
2. Jeddah King Abdulzaziz international airport, Saudi Arabia (JED)
3. Kathmandu Tribhuvan international airport, Nepal (KTM)
4. Manila Ninoy Aquino international airport, Philippines (MNL)
5. Tashkent international airport, Uzbekistan (TAS)
6. Paris Beauvais-Tille international airport, France (BVA)
7. Frankfurt Hahn international airport, Germany (HHN)
8. Bergamo Orio al Serio international airport, Italy (BGY)
9. Berlin Tegel international airport, Germany (TXL)
10. New York City LaGuardia international airport, USA (LGA)

Islamabad had been ranked one on the list of world's 10 worst airport terminals because it had been likened to that of a prison. Officials of the Islamabad Benazir Bhutto international airport have yet to comment on the latest survey done by Guide to Sleeping in Airports.
