Being a flight attendant might seem like a dream job (free travel AND free peanuts?!) but it is actually a lot more difficult than many people realize. As it turns out, there are a lot of things people don't realize about being a flight attendant—and about flying in general. And learning the truth could forever change the way you treat your flight attendants as well as your general behavior on flights.
Someone asked flight attendants of Reddit: "What are some things we as passengers don’t know when we fly? Also what are the negative aspects of your job?"

When people ask for the reason for a delay, we usually give a bullsh*t response because the REAL answer would spook passengers. "We have a minor technical problem and engineers are on their way" And in reality: The cabin pressure isn't working.
