A new study has shown that air in an aircraft cabin is not so much of a health threat, considering that it is as good or as bad as the air in an office environment.
According to the research by the National Research Council, an airplane is as likely to make you sick as any other enclosed environment, such as a cinema or an underground train.

He said cabin air was refreshed about 15 times an hour, compared with fewer than 12 times an hour in an office building.
On most trans-Atlantic jets, the air is filtered through hospital-grade filters that are designed to remove 99.97 per cent of bacteria and the tiny particles that carry viruses.
Cabins are also separated into ventilation systems covering every seven rows or so to limit the spread of germs through the plane.
