In the United States, federal judge Kathryn Kimball Mizelle has lifted the mask requirement on public transportation, including airplanes. The court declared them illegal and justified the decision with the fact that the health authority CDC had exceeded its powers.

In the United States, there has been significant opposition to mandatory masks on board airplanes and other forms of public transportation in recent months. Several airlines and Republican lawmakers have repeatedly called for immediate repeal. While the federal judge's decision must be implemented immediately, the White House and the Justice Department can appeal it.

More and more states are completely lifting the mask requirement and no longer require mouth and nose protection to be worn on board aircraft and other public transport. Austria is going its own way, because people continue to insist on FFP2 masks in airplanes and supermarkets, for example, while they are no longer required in coaches and discotheques, for example.
