The V.I.P.s (1963) - stars a whole bunch of people: Elizabeth Taylor, Richard Burton, Maggie Smith, Margaret Rutherford, Orson Welles..... the list goes on.
It takes place at an airport. It's not as good as Up in the Air, Catch Me If You Can, The Terminal, Warm Bodies, Air Force One.... or, well, any other movie you can possibly think of that takes place at an airport or on a plane.
The highpoints? Maggie Smith (naturally) and Margaret Rutherford as the Duchess.
