I am traveling from Florida to Boston this Friday. Will I be required to quarantine 14 days without a negative Covid test result? Is there someone at the gate physically there to make sure each passenger has a negative test result?

No. We did not have to quarantine. They were not taking passengers temperature either.

MAss will require 14 days or a negative test when you come back. Check what Florida is requiring. Each state is different

I traveled boston to PR and I do the test 3 days before and I fill a for from pR government with the test results so the they send me a code when I arrived to the airport they scan my code...
