Flying BKK-DXB-BOS in a few days. Curious about what type of test and when we need to get it. We have 19 hour layover in DXB, so spending the night in DXB flying out the next morning. Do we get a PCR in DXB and are good to go all the way to BOS or will we need to take PCR in DXB for DXB-BOS. Both fully vaccinated. Emirates won't allow antigen as I recall?

Thanks!
