As far as Europe is concerned, AMS must certainly one of the first.
The first one was installed in 1961. In 1967 the central terminal was opened with 25 gates, each equiped with one aerobridge.
Which airport in was the first in the world to introduce over-the-wing type of aerobridge?
It could very well be AMS which had its first one installed in 1970. Basically this is a dual aerobridge in one single gate. The front bridge serves the front door; the second bridge hangs over the wing and can reach the very last door of a DC10/M11, or on a 747/744 the door directly behind the wing. This provides a great deal of flexibility for loading/unloading/servicing the wide-bodies.
