Those that top its charts for worst airports in the world collected the most negative feedback from voters over the past year.
These airports fall flat in terms of providing any kind of enjoyable overall airport experience.
It said “instead, they’re dirty, uncomfortable, unfriendly and lack the most basic of services and amenities. They elicit passionate critiques from those who visit them, and countless warnings for future travellers to avoid these places at all costs.”
However, in its 2015 Airport Survey, the travel website reported that while Changi International Airport, Singapore, was named the best, the Port Harcourt International Airport, in Rivers State, Nigeria was named the worst international airport in the world.
Of the 10 worst international airports in the world, the Nigerian airport was the only African airport on the list.
