Are you willing to get the Covid vaccine when offered?

Do you have a source for this? I'd like to pass this on to a family member who will be traveling to the US in a few weeks.
I forgot about VeriFly.

Depending on the airport you are coming from outside the U.S. and the airline you are flying, you may or may not be able to check in and get your boarding passes via internet before you go to the airport. You can use VeriFLY to "show" your covid test when checking in via the web, and get your boarding passes. Otherwise, you will have to check in at the airport counter/kiosk and show your test to an airline agent, which may be a pain depending on the airport you are flying out of.

I normally fly from Mérida to Miami, and the airport in Mérida doesn't have many international flights, so checking in at the counter/kiosk at the airport is no biggie, takes no time, and I don't want to use VeriFLY - net anonimity!!! But the last time I had to fly out of Cancún to Charlotte, on the 4th of July holiday week, and the lines to the counter/kiosks were brutal.
