I’m a former flight attendant. Here are 9 things I wish passengers would stop doing on airplanes.

• I was a flight attendant for nearly 10 years and I witnessed some of the worst passenger behaviors.
• I saw far too many people go to the lavatory barefoot or blast music without headphones.
• We also know if you’ve snuck into an empty business-class seat.

Pillows, blankets, and safety gear aren’t personal souvenirs

Don’t direct frustration at the parents of crying babies

But here’s what I always wanted to tell them: You might fly often, but you don’t fly on the same aircraft every time. Every plane model is different, and emergency exits aren’t always where you expect them to be.

Taking three short minutes to check where your nearest exit is won’t hurt, and it shows the crew some respect for the safety job we are actually trained to do.
