The Q&A website Quora recently polled flight attendants on what they “know about flying that they don’t tell passengers,” prompting some helpful and horrifying responses. While some details are juicier than others, there’s a lesson to be learned from each. Here are some of the findings.

  • The most unhygienic thing in the aircraft is the seat belt, then the tray tables. Trays should be disinfected before using since sometimes passengers put their feet on them.
  • It’s not all gloom and doom: One attendant writes “at times, the crew offers you their own meal to make sure you are fed on the flight.”
  • Sometimes rough landings are necessary, especially when it’s raining, but airplanes are built to withstand thunderstorms and turbulence.
  • Book a morning flight because the air is less bumpy and there is less chance to hit a thunderstorm, as these tend to happen mostly in the afternoon.
