Probably NYC, because she usually flies Delta Airlines and at this time there are only Delta flights to NYC from Miami's International Airport, and other places that she usually doesn't go. No Turkey flights of any company, so at least she isn't going there. The other likely flights from other airlines are to LA or San Paolo. Adrielle posted about flying somewhere too around the same time, probably to Brazil, but she didn't show Adriana with her too.
If you wonder how I know this, I just used this very nice website that tells you the planes that are flying from a certian airport at a certain time, and the destinations with approximative arrival hours too:
