Flying brings people from all over the world into one small metal tube for hours. Airports and airlines have clear safety rules but there are also unspoken habits passengers repeat that create discomfort. Here is a look at ten common things people keep doing on flights even when it is better to avoid them completely.
Drinking Carbonated Beverages on Board

Gas bubbles in your drink expand when the plane goes up high. This simple fact can cause a lot of pressure in your gut. You might end up feeling sick during the whole flight. Drink some orange juice or water to keep things simple. Your body will definitely thank you later.
Taking Off Shoes and Socks

Kicking your shoes off feels great but doing it in a cramped space can easily make the people sitting next to you very uncomfortable if any smells escape. Keeping your footwear on is just basic common courtesy when you share such a small row with strangers.
Staying Glued to Your Seat

Sitting in the exact same position for a long flight slows down your blood circulation and that can lead to some leg swelling or worse. Standing up to stretch your legs when the seatbelt sign turns off helps keep your body feeling fresh and ready for vacation.
Letting Kids Run Down Aisles

Flights are a time when many travelers try to catch up on sleep or finish work so having children sprinting around the cabin is super distracting. It is also a safety hazard for the kids if the plane suddenly hits unexpected turbulence while they are out of their seats.
Wearing Contact Lenses During Flights

The recycled air inside a plane cabin gets incredibly dry and that quickly makes contact lenses feel like rough sandpaper on your eyes. Swapping them out for your regular glasses before boarding saves you from spending the whole trip blinking and rubbing your face.
Making Jokes About Security Threats

Airlines take security incredibly seriously so dropping a bad joke about bombs will easily get you pulled into an interrogation room instead of your destination. You might think you are just being funny but airport staff have zero sense of humor when it comes to passenger safety.
Drinking Too Much Onboard

Having a bunch of drinks might sound like a fun way to pass the time but the altitude makes that drink hit you much harder and faster. Dealing with a spinning head and an upset stomach while stuck in a middle seat is a guaranteed way to have a terrible flight.
Sleeping at the Wrong Times

Passing out on a red eye flight sounds smart until you land in the morning and realize your internal clock is completely confused. Staying awake when it is daytime at your final stop really helps your body fight off bad jetlag so you can actually enjoy your trip.
Trying to Open Cabin Doors

It sounds wild but there are actual cases of passengers trying to pull the emergency exit doors open while the plane is still moving. This seriously compromises the safety of the flight and doing it leads to severe panic and possible jail time.
