1973 — Peg Bracken, But I Wouldn't Have Missed It for the World!: The Pleasures and Perils of an Unseasoned Traveler, Harcourt Brace Jovanovich (1973), →ISBN, page 251:
A nice sense of when to speak, if ever, to the person beside one is a good part of airplane manners, or jetiquette.
1985 — Mark Muro, "Unfriendly Skies", Boston Globe, 13 October 1985:
Call it the demise of "Jetiquette" if you want, but no matter: if Hanrahan's comments and those of a number of flight attendants and travelers suggest anything, it is that as deregulation labors through its seventh year thousands of Hanrahan's fellow air-travelers now believe civilization is foundering on the vinyl seats of the airlines. Increasingly, they report, airport waiting areas look like bus stations, airline passengers like the grim wanderers of subway tunnels.
1995 — Alan Peppard, "Chucking the social life", The Dallas Morning News, 8 October 1995:
Town & Country magazine continues its ongoing mission to bring enlightenment to the darker regions of the continent with its October story on jetiquette — that is, how we conduct ourselves when invited on someone's private jet.
The couple has hired Alexandra Penney, former Self magazine editor in chief, to create original editorial content for the site, such as an upcoming story on "jetiquette"--the manners and mores of private jet travel.
