Yes, you think others are wrong. In this case it is clear that the airline is doing the ethical thing. Their workers are not unionized. Not because of union busting for lower wages, but because they pay them well enough so that in a competitive job market the employees still see that there is an advantage to represent themselves. They are well paid, so the argument "what if they cannot afford the extra $200 fails".
...I'msorry, but that is an absurd oversimplification of why non-union employees don't unionize. "We get paid plenty here" is rarely the reason. Do you know how much a typical flight attendant makes?
No one is saying that they will lose their coverage. They will only pay an extra $200. per month because they refuse to perform a reasonable act.
And again, if they can't afford to pay that, what happens?
And do you know who else supports this sort of surcharge? Obama. In the AOC a surplus can be charged to smokers. And not a small one either. Smoking is an act that everyone else has to pay for if that is not the case. That is not ethical. Covid care is something that everyone else has to pay for that is not fair to do their part to end this.
If they can charge extra for smokers, which is an addiction by the way, very hard to quit, they can charge extra for not getting a vaccine that is so close to painless that I did not feel when I tried to:

"Obama supports it" is just an appeal to authority, so I don't find that terribly persuasive.
Again, my preference is for a system of universal care that addresses social determinants of health rather than the carrot/stick individual behavior approach. You disagree. Okay.
