13 tips to avoid getting sick on a flight

There is nothing worse than getting off of a flight to feel a cold settling in.

And while you can't predict when you'll be on the same flight as someone who is sick, there are steps you can take to walk out as germ free as possible. Here are 13 tips to help you stay healthy on a plane.

Don't drink the tap water

In 2007, The Wall Street Journal conducted a study from 14 different international and domestic flights. Their results revealed traces of everything from Salmonella to tiny insect eggs lurking in the water.

Skip getting any ice in your drinks

While ice usually comes from outside vendors, some large-size planes have their own ice-making technology and will use the water from the airplane tanks to make the cubes, according to CNN.

Avoid using the blankets and pillows

In another investigation by The Wall Street Journal, airlines were found to wash their blankets and pillows every five to 30 days.

Don't touch the tray table

The tray table is one of the dirtiest parts of a plane. Flight attendants have admitted to only washing tray tables once a day and some have even seen parents changing their children's dirty diapers on them.

The best thing to do is to wipe it down with a disinfectant and to absolutely avoid eating directly off of it.

Order a hot meal

In 2009, LSG Sky Chefs - one of the largest airplane caterers - was caught in a major scandal when the FDA found traces of insects in their facilities and the use of unwashed gloves and bare hands to prepare airline food. Another catering company, Gate Gourmet, also dealt with similar issues regarding bacteria and mold being found in their food.

Avoid aisle seats

Some scientists say that sitting on the aisle seat leaves you more at risk of being exposed to germs as it puts you closer to passengers who are regularly coming and going from the restroom.

Use the air vent above your seat

Take precautions when using the restroom

Use a nasal spray

Don't drink coffee or tea

Don't place your items in the seat-back pocket

Besides the possibility that the seat-back pocket can be filled with anything from used tissues to trash, studies by Auburn University's Department of Biological Sciences revealed that armrests and seat pockets are the worst areas to touch since bacteria like E. coli can survive there for days.

Ask to change your seat if the person next to you is sick

While this might not be possible on fuller flights, if there are open seats on the plane, asking to be moved due to someone close by who is sick isn't uncommon.

Stay hydrated

Drink ample amounts of water to counteract the dry air found in airplane cabins. Plus, staying hydrated will help prevent dehydration, which can cause headaches, cramps, and fatigue.
