Limited Traffic Information - you are thinking of the "Airport" series, the original based on a novel by some american bloke whose name escapes me until I hit the "submit reply" button.
There were "Airport", "Airport 77", "Airport 80 - The Concorde" and probably some others that were too bad to register on the consciousness.
"Airport 80" was in fact a good deal funnier than "Airplane" - I just love the bit where the Captain sticks his hand out of the DV window in flight to fire a flare which decoys a Sparrow fired from an F4 owned by some long forgotten bad guy. Classic! looping the passnger carrying Vulcan Mk3 with 100 POB was great, too.
Good flims: "Battle of Britain" is priceless - not just for Susannah York in webbing and "Aces High" should rate a mention too.
Aces High contains a great line from David Wood (who was a regular on Play Away, with Brian Cant and Jeremy Irons): To very junior pilot in a french brothel "despite what Mummy said to you, it was not made for pissing through". I was 9 when I saw the film first time - that line stuck!!!!
