I am actively flying post vaccination. I feel very comfortable about it. Mind you, I've only sat next to my husband or an empty seat. I don't think I'll feel as comfortable next to a stranger. AS is the last carrier to be blocking middle seats for elites and that ends with the end of this month. Flights are filling up. Regardless, I am really enjoying seeing some of the US. I've chosen nonstop flights to date to cut down on my time masked and any small risk having time in an additional airport.
