In Switzerland, all corona measures, including the obligation to wear masks on public transport, will be lifted with effect from April 1, 2022. Swiss will then no longer make it compulsory to wear mouth and nose protection.
In practice, however, there are restrictions because if the destination country of the flight still mandates masks on board aircraft, Swiss must ensure that passengers wear masks. This means that according to the current status, for example from/to Austria and Germany, there will be no changes. The Alpine Republic even prescribes the wearing of FFP2 masks.
If there is no such arrangement, masks no longer have to be worn on board the Swiss fleet. This also applies to the crew members. The carrier wants to inform passengers before departure whether or not mouth and nose protection, or even FFP2 masks, have to be worn due to official regulations.
More and more countries are lifting all corona measures and freeing their citizens from the unwelcome masks. In Austria and Germany there is currently no indication that this regulation will be lifted in public transport. In the Federal Republic of Germany, the rule is strictly adhered to in public transport, including on airplanes. The current Austrian regulation, which will expire shortly after Easter, also provides for this and it is not foreseeable how the government will then behave.
