''Airport'' is the first of a 1970s series of disaster movies centering around aircraft in distress. The first, award-winning movie became the TropeCodifier for the DisasterMovie genre. Based on the novel of the same name by Arthur Hailey, it can be considered a very close and faithful adaptation; the sequels, however, have nothing to do with an original book.

The movie begins with the day-to-day concerns and life issues of various crew and patrons of Chicago's fictional Lincoln International Airport ([[CaliforniaDoubling actually, a redressed Minneapolis-St. Paul Airport]]). The central drama to this movie seems to be marital problems; first in the guise of difficulties between [[TheHero airport manager]] Mel Bakersfield (Creator/BurtLancaster) and his wife. Mel has a rivalry with his brother-in-law, [[DirtyOldMan Vernon Demerest]] (DeanMartin) over who's right about airport operations. Demerest also happens to be doing the deed with one of his flight attendants, Gwen Meighen (Jacqueline Bisset). However, Mel is fortunately not alone; he does have help from his friend, Trans-Global Airlines Supervisor of Passenger Relations Tanya Livingston (Jean Seberg) and TWA Chief of Maintenance Joe Patroni (George Kennedy) in the numerous challenges... usual and unusual.

A wrinkle that will disrupt the whole flow of things is a despondent, suicidal passenger (Van Heflin) who plans to bring down an aircraft via a bomb. He's only partially successful, and now the stricken plane must be brought to safety -- and another airliner is stuck in the snow on the only suitable runway. Can the ground crew get the stranded aircraft cleared from the runway in time?

Helen Hayes' performance as Ada Quonsett won her an Oscar, and the movie was very well received in general.

''Airport'' spawned three sequels: ''Airport 1975'', ''Airport 1977'', and ''Airport '79'' (in a Concorde!). A TV-movie and miniseries was also created in the aftermath of ''Airport''; ''SanFranciscoInternationalAirport''. (The miniseries simply dropped the word Airport). Today, it's probably best known for having inspired ''Film/{{Airplane}}'', TheParody of '70s disaster movies.

!!Tropes present in the original ''Airport'' include:
* AnyoneCanDie: [[SubvertedTrope Subverted]] in that [[spoiler:there's only a single death, that of Van Heflin's character, mad bomber D.O. Guerrero.]]
* BreakoutCharacter: Joe Patroni.
* TheChessmaster: Mrs. Quansett, professional airplane stowaway, having stolen hundreds of rides and has an arsenal of tricks. She uses her advanced age to get away with a number of schemes, including faking illness to get rid of the man who is supposed to babysit her (and keep her from stowing away on another plane) and defeating Mrs. Livingston's attempt to keep her from doing so. The book makes this explicit: both Mrs. Quansett and Mrs. Livingston independently realize the two of them are battling to see who can win. The result: age and craftiness defeat youth and inexperience.
* CoolOldLady: Ada Quonsett.
* CoversAlwaysLie: The DVD cover adds a fire effect to the 707. At no time is fire seen in the movie.
** The Blu-Ray release uses the same basic cover, but with the fire removed.
* DevelopingDoomedCharacters
* DisasterMovie: The TropeCodifier.
* DownerEnding: For some characters.
* TheFilmOfTheBook
** AdaptationDisplacement
* HeDidntMakeIt: Used straight to indicate someone failed to do something, not as in the typical euphemism for "someone died."
* IdiosyncraticWipes
* {{Jerkass}}: That one [[UnsatisfiableCustomer whiny, surly bald passenger]] (played by Steven Turgeon). Even a priest felt the need to hit him!
** The smug pilot that strands the plane from earlier, providing half the plot.
* KilledOffScreen: [[spoiler:D.O. Guerrero, when he detonates his bomb in the lavatory, tearing a hole in the wall and sucking him into oblivion.]]
* SecretRelationship: Deamerest and Gwen, resulting in a pregnancy.
* SplitScreen: Used several times. Very ''de rigueur'' for a 1970 film.
* TemporaryBlindness: [[spoiler:Gwen.]]

!! Tropes present in ''Airport '75'' include:

* BillingDisplacement: Charlton Heston is billed first, but Karen Black's character gets the most focus, as well as screentime.

!! Tropes present in ''Airport '77'' include:

* TheCameo / DemotedToExtra: Patroni, although he has more screentime in the original version.
* CoolOldGuy: Philip Stevens.
* SomethingCompletelyDifferent: While it stays with the plane theme, this film takes the action out of the airport (and skies, for the most part) and sets it in the underwater depths of TheBermudaTriangle.

!! Tropes present in ''The Concorde: Airport '79'' include:

* AscendedExtra: Patroni at least becomes this from his previous appearance.
* BigBad: Harrison.
* TheCameo:
** Charo. Sadly, she was not nominated for Best Supporting Actress at the Oscars that year.
** Creator/BibiAndersson as the prostitute that Patroni hooks up with in Paris.
** Ed Begley, Jr., as one of the members of the Concorde rescue team.
** In the TV version, Jose Ferrer and JD Cannon appeared as investigators looking into Harrison's background.
** Although not cameos, half the cast are billed as "guest stars", with some getting very little to do.
