There have been many film related to aviation. The more documentary style like Freefall (Air Canada flight running out of fuel). The more serious kind (Airport part 1 to 100). Wesley Snipes also did a movie on board of a plane.
But .... in my opinion Flying High with Robert hays and Julie Hagerty is the best ever. The scene in the cockpit just before take off and the scene where the FA is blowing the autopilot are killing
Any more suggestions for best airline/airplane related movie?
