The quality of air onboard an aircraft is much better than in most indoor environments. This along with the mandatory usage of masks and the tests and/or vaccination certificates requirements, make the risk of contracting COVID-19 onboard an aircraft to be very low.

This video shows you additional factors lowering the risk of virus transmission in the cabin of an aircraft:

How good is the cabin air?

The risk of transmission in the modern cabin environment is low because passengers face the same direction, seatbacks act as barriers, and air is flown from the top to bottom, but also because the air is very clean.

  • Cabin air is refreshed 20-30 times per hour, which is 10 times more than most office buildings.
  • Cabin air consists of half fresh air and half High-Efficiency Particulate Air (HEPA)-filtered air, which remove 99.993% of bacteria and viruses. HEPA filters are those also used in hospital operating theatres and most modern aircraft are equipped with such filters.
