The Russian Skyteam member Aeroflot is currently considering setting up special zones in the aircraft for people who do not want to wear a mask. The reason for this is that mask refusers have become an increasing problem for the carrier.
It is envisaged that, for example, the last two rows should be declared a mask-free zone. This area should also be available to people who cannot wear an MNS for medical reasons. The exact implementation has not yet been determined, but the new zones are intended to minimize increasing problems above the clouds. In the past few weeks there have been repeated incidents during the flights.
