We got married in Bahamas. She came the long route from Colombo to Grand Bahama transiting through Dubai, Brazil, Panama, and finally Nassau.
There is a flight route from IST (Turkey) to PTY (Panama) to NAS (Bahamas). It is important to check flight routes and transit without visa requirements.
For an example, PTY has transit without visa for my spouse but she must depart PTY within 12 hours and must show the onward ticket. When she arrived in PTY, while rushing to the next gate (1 hour layover), she asked a airport official for directions. They signaled to Panama Immigration Officials and they came and questioned her on the spot. She quickly showed that she is leaving and showed the onward ticket from PTY to Nassau.
Check the passport and visa requirements from https://www.emirates.com/us/english/before-you-fly/visa-passport-information/ Make sure to enter all the countries she would be transiting through and carefully read through the exemptions.
