One air hostess commented: “Ive done the safety demo hundreds of times at work and each time I do it only half of the passengers look up and watch.

Another added: “As a former airline employee, for over 35 years, I find it devastating to see this picture of people wearing a mask the wrong way.
“I am glad you pointed out that people need to put their stupid phones down and pay attention.”
