We all know we shouldn't be a Karen, but also be careful to avoid being a Philip ... That's the code name that flight attendants give to troublesome passengers. No, guys named Phil aren't known for being pains in the butt – the name is a take-off on the old airline code "PILP," which stood for "passenger I'd like to punch." The quickest ways to get labeled a "Philip" include constantly ringing your call buzzer, complaining about babies crying, and filming the crew. That last habit, by the way, is officially banned on a number of airlines, including United, American, Delta and Southwest.
