The Most Dangerous (And Expensive) Airports Ever Built

90. Frankfurt Airport – Germany

Year of construction: 1936
Risk factors: Congestion, confusing layout

Frankfurt Airport has been criticized for its layout time and again. As one passenger put it on a review site, the airport “makes no sense” and is “connected by a maze.” There are a lot of escalators, tunnels, elevators, and staircases that seem to lead people to random detours.

Part of the reason the airport is frustrating also has to do with congestion. Frankfurt is the busiest airport in Germany, as far as passenger traffic goes. It has four runways, two terminals, and can handle a maximum of 65 million passengers per year, many of whom have commented that the airport is confusing.
