Every CA I’ve flown with would do everything in their power to never leave anyone at the gate. Now we have 90% of our CAs who got the vaccine for a multitude of reasons (some to protect sick spouses/family or their own underling conditions) and 10% who are being forced to get it. They will also have to deal with us FOs and our FAs who also got the vaccine. I bet you will have mixed results, but that is just a guess?
