CottageGirl - Slightly different process for leaving by air from BVI, if memory serves. Neg test required...they'll ask for this when you check in at the airport. I think we may have also been asked for proof of vax.

When you arrive in PR you'll need to collect your bags and go thru customs. On your way upstairs to the departure level you will be asked for the PR QR code, but tell them you are just connecting and won't be leaving the airport....show your tickets or boarding pass. Then you have to the USDA? bag scanning area and they'll put an inspection sticker on all your bags (carry on and checked). Once you've got that done you can proceed to the airline check-in counter to recheck your bags. Then thru airport security to your gate.
