Air travel is generally not a fun and carefree experience. But there are many ways you and your fellow passengers can make flights less miserable. Specifically, there are certain things you can avoid doing in order to foster a more pleasant journey for all.

To guide travelers toward this goal, HuffPost asked some etiquette experts to identify the faux pas they often witness people committing while flying, and their advice on how to avoid repeating them. The answers mostly come down to having respect for others and setting a good example.

When youre trapped in a small space, you have to have extra good manners . I cant get off and move away from you on an airplane the way I can in a subway car, said Jodi R.R. Smith, president of Mannersmith Etiquette Consulting .

The kinder you can be, the better you can help to create an atmosphere where were all a little bit caring. We all need to get to the destination as quickly and safely as possible, and a little bit of kindness and understanding can go a long way, Smith added.

Without further ado, here are 15 of the rudest things you can do on a plane.

Bring Pungent Food On Board

If you want to bring a snack or meal on board, avoid messy or smelly foods. When youre in a small space, pungent odors will spread, and its particularly rude to passengers sitting next to you.

A tuna sandwich or hard-boiled eggs are better served in a home or restaurant, where there is more air and better air filters, said Diane Gottsman, national etiquette expert, author of Modern Etiquette for a Better Life , and founder of The Protocol School of Texas .

Beyond food smells, Smith advised being mindful of your body odor.

If Ive just run the New York City marathon, Im going to take a shower or at least try to give myself a bit of a sponge bath in the airport bathroom before I sit down next to you for a cross-country flight, Smith said.
