You can also decrease the risk of becoming ill by keeping sanitised onboard even if no one is visibly sick.
This is done by washing your hands regularly and covering your mouth while coughing or sneezing to prevent your germs spreading in the plane.
According to a recent study, the window seat is the best because not as many germs circulate towards the windows of the plane.
This can also help decrease your risk of picking up germs because you have not moved from your seat at all during the flight.

Also, another way to avoid getting sick onboard is to always keep your air vent on, even if it does get cold.
Keeping a constant fresh airflow directed towards your face and body can help germs in the air away from you.
Germs can be harder to avoid if it is a flight attendant or staff member who is sick onboard. This is because they are constantly walking up and down the aisles and reaching over to passengers to hand food and drink.
This means it is imperative that cabin crew do not fly when they are sick as they could be infecting lots of people at once.
However, if you are sick, it is recommended that you do not travel at all and wait until you are completely better before boarding a plane.
