Airplanes are highly safe to travel because the air that circulates inside the cabins is
always being filtered. For this reason, most viruses and bacteria do not spread very easily.
Several airlines have stated that the risk of being infected with COVID-19 on a plane is as low as in a hospital operating room.
Airports are following stricter biosecurity protocols. Therefore it will be normal to have more distance within the lines. It is recommended that all passengers check-in online, for safety and to speed up the lines.
Additionally, most airlines now have very flexible policies on cancellation and change of routes and dates on their flights.
