Boarding passes we’re obtained the day before. No change from pre-covid. We did not have to show testing paperwork in Boston. We did have to show the testing paperwork in Miami - at the gate. I got a little nervous as the woman took a while looking at the covid-19 results. She explained that the paperwork varies. Our results were quite intricate, clearly stating negative but the RT-PCR wording was not easy to find. Don’t stress too much. If the hundreds of travelers visiting can do it, so can you!
