Flight attendant lines board with the safety demo — exits, seatbelts, turbulence and putting your own mask on first. The uniform mythology does half the work; the in-flight vocabulary does the rest. Layover bars are the genre's true home.
Mid-flight delivery to working crew is the one forbidden runway: they are professionally required to smile at you, which removes the only honest signal flirting has.
The genre's truth is that crew romance happens at the layover bar, not at thirty thousand feet — mid-flight material is strictly for entertaining the person you boarded with. The safety-demo vocabulary carries the comedy: exits noted, masks first, brace positions optional.
Airport hotels and crew bars are the actual venue, where the uniform is off duty and the stories are better than yours. The pilot lines hold the flight-deck material, the travel register continues in the places collection, and the whole crew roster is in occupations.
