After making sure I take a shower before I travel, my second most important flytiquette rule is:
“Under all circumstances, respect the cabin crew, pay attention to their instructions and thank them for their help”
I have traveled to every continent in the world, using dozens of different airlines, which means I have probably interacted with hundreds of pilots, flight attendants, and other cabin crew members, both in business and economy class. I have found different level of services that made my flight more or less pleasant, but I always have followed my rule because I found it very important.
When you travel by airplane, you have hundreds of people inside a little cabin, trying to get somewhere. They are traveling with their anxieties and their fears, as well as their good mood and cultural diversity, and all of them are trusting the pilots and cabin crew will get them to their destination, safe and on time.
A lot of things can go wrong in a flight, and the cabin crew is the only barrier between those things and the passengers. Yes, they also serve food, bring drinks, make jokes and all that, but their main responsibility is the safety of the people traveling in their plane.
When you understand that, you realize that even if you are having a bad day, their day is probably more challenging than yours. Behaving properly during your flight and paying attention to the cabin crew’s instructions is the least you can do, isn’t?
Due to that, one of the most important flytiquette rules I follow is to respect the cabin crew and always tell them “thank you” when they help me with something. Sometimes, I even get a nice smile back when I do it. A person that cares for my safety and even smiles at me is definitely someone deserving my full respect.
