Airport 1975 (1974)

Has anyone here seen this film? I just caught it on Youtube and while I recognized parts of Dulles, I'm also astonished by how much of the interior design has changed.

I remember landing there a few times as a child in the 1990s and being there again once or twice in the late 2010s. The film, being from the '70s, makes it look practically like a different world even though the iconic shape of the building is still there and as impressive as ever.
