Airlines, protective masks, and social distancing have been very much in the news recently. Travelers complained of full flights — including at least one with some passengers not donning masks.

Most airlines — and several airports — announced mask-wearing requirements for all travelers.

But a highly-publicized, Reuters investigative report said the “top three U.S. airlines have told their flight attendants not to force passengers to comply with their new policy requiring face coverings, just encourage them to do so.”

So the rules aren’t really rules, are they?
