Things you should never do on an airplane

Don't drink soda -
An increase in altitude may cause intestinal gas to expand up to 30%, so you might want to avoid consuming sodas. Keep your stomach settled with water.

Don't use the blankets and pillows - Shockingly, those offered blankets and pillows don't get a thorough cleaning between flights.

Don't wear contact lenses -
Opt to wear glasses in flight. The air in the cabin is very dry and can cause irritation to your eyes. 

Don’t walk around barefoot -
Walking around barefoot on a flight is definitely a no-no, as the floor is full of germs, especially in the bathroom.

Don’t fall asleep against the window/wall - You have no idea how many people have leaned against that wall, and even sneezed and coughed against it. 

Don’t try to cut the line when you’re disembarking - It's understandable that you want to get off the plane as quickly as possible, but cutting the line is just rude. 

Don’t touch the flush button in the bathroom - The bathroom is a major place where germs hide out.

Don't drink the coffee or tea -
You don’t want to drink anything that could possibly be made with the tap water from the plane. 

Don’t recline your seat during take-off or landing - According to the Federal Aviation Administration (FAA), it's illegal to recline at the very beginning and end of flights. 

Don't go for the ice -
Most airplanes don’t serve drinking water from the tap, but their ice cubes are often still made from the same water, which can be filled with bacteria.

Don’t overdo it with alcohol -
Alcohol is extremely dehydrating. Combined with the low humidity of the plane, your body’s in for a drying experience.

 Don't argue with the flight attendant - Flying makes some people very irritable, especially when something goes wrong.

Don't forget hand sanitizer -
A hand sanitizer will be your best friend on a plane. 

Don’t close the overhead bins -
You might think you're being helpful by closing the overhead bins that appear to be full, but it's actually up to the flight crew to make that determination.

Don't try out new sleep medication - Be careful when trying a new medication, as finding out mid-flight that you’re allergic to one of the active ingredients is not going to be fun for anyone.
