* AllStarCast:
** The original movie starred Creator/BurtLancaster, Music/DeanMartin, Helen Hayes, Barbara Hale and George Kennedy.
** Aside from George Kennedy's reappearance as Patroni in ''Airport '75'', there's Creator/CharltonHeston, Karen Black, Efrem Zimbalist, Jr., Susan Clark, Helen Reddy, Linda Blair, Sid Caesar... the list just keeps on going.
** ''Airport '77'' had Creator/JimmyStewart, Creator/JackLemmon, Brenda Vaccaro, Lee Grant, Creator/ChristopherLee...
** ''Airport '79'' also featured an ensemble cast, though its actors were more famous for their TV work.
* BillingDisplacement: Creator/CharltonHeston in ''Airport '75'' is billed first, but Karen Black's character gets the most focus, as well as screentime.
* Creator/Backlash / MoneyDearBoy: Creator/BurtLancaster only agreed to star in ''Airport'' in order to get some non-commercial films made. His contract gave him a 10% profit participation once the movie hit $50 million, and the film grossed $45.3 million in North America alone. Despite the financial windfall, Lancaster said that the movie was "the worst piece of junk ever made."
* FranchiseKiller: Almost everyone agrees that ''Airport [='79=]'' was the end of the line for the series.
* PlayingAgainstType: In ''Airport '77'', Creator/ChristopherLee, frequently cast as a suave villain, plays the selfless Martin Wallace who [[spoiler: sacrificed his life when he tried to help rescue the other passengers.]]
* WhatCouldHaveBeen: According to John Wilson in "The official Razzie Movie Guide", there were plans for a FIFTH movie to be called ''Airport 82: UFO'', a [[WereStillRelevantDammit blatant attempt]] to [[FollowTheLeader cash in on]] the hot new wave of sci-fi cinema. Numerous contemporary news articles (which also use the name ''Airport [[Trope2000 2000]]'') describe it as a "[[Mohs/SpeculativeScience science fact]]" film (well, not counting the giant alien spacecraft that engulfs the plane) that would have moved the action to TwentyMinutesIntoTheFuture. George Kennedy was slated to return, naturally, and even turned down an invitation to appear in ''{{Film/Airplane}}'' so as not to undermine his opportunity to work for this franchise. Presumably, ''Film/AirplaneIITheSequel'' killed this film by pre-emptively parodying it.
