Our Verifly experience DFW-MIA-SXM. We uploaded our vaccination cards and completed the questionnaire. We received the green check mark of approval. We then were able to check in online and get mobile boarding passes. At DFW we went straight thru security and did not have to present any documents to anyone. We do carry on only but did see a AA kiosk that said if you were checking bags you could scan your boarding pass and the kiosk would print your luggage tags. It then sent you to a designated are to drop off your bags. At MIA we had to present our passports to board the plan. It was a very easy process. I will report our experience on the return trip next week. Hope this helps someone.
