Any issues leaving the SJU airport for lunch and coming back through security from a Covid perspective? If you are already checked into your flight to the US, can you just go back through security? Do you need to provide vax card and negative test again?
We have a 6 hour layover.
technically, you need to fill out the PR safe travel portal and get approval to leave the airport. Will anyone notice if you pretend to be in-transit and go for lunch? probably not but it's a big risk in my mind.
