I have a number of friends who work as flight attendants. One of them recently retired after 20 years flying for the most storied name in commercial aviation, while others work for less glamorous domestic U.S. airlines. I asked them what they’d tell their passengers if they could tell them anything at all, or what secrets they’d reveal only if granted complete anonymity. All I can say is that these people do not represent every single flight attendant in the skies, so if you’re a flight attendant yourself, please hold your fire and don’t shoot the messenger. But I didn’t make this stuff up.
