I took a flight from one European city to another last week. Both cities/countries were not on top place in covid-19 case ranking (not even close to top20). It was mandatory to wear mask during whole flight. Guess what - almost 90% of passengers put masks off after the plane took of. And cabin crew did not even bother about it...
ROFLMAO.... Here in India, you need to wear a PPE kit for the entire duration in case you want to travel in flight. The kit is being provided by the airlines and they are charging around $15 from the passenger for that. Since it is affordable, no one is complaining. But these measures hasn't slowed down the spread of COVID 19 pandemic here. Nowadays on average we are having ~40,000 new cases per day.
