But you don't have to go on the plane either if you feel it's a risk do you?
If you bought the ticket in good faith that everyone on the plane was going to wear a mask - and you got seated next to the entitled whiny parent of the 2 year old who can't be socially responsible because their little darling doesn't want to wear a mask - you can take a running jump.
It is up to everyone who buys the ticket, and I'm pretty sure when you buy tickets you tick a box to say you have read the T&C and agree to abide by them, to keep to the rules. If you don't - you don't fly. And that includes all the entitled parents of the next generation's rule breaking scroats to ensure they comply. Or they don't fly.
a bit of personal, not to mention, social responsibility is severely lacking in so many people on this thread (and I'll assume in the population at large) it is staggering.
