What I had to do here is look up for a round trip ticket, write down the airlines, flight numbers, and time for the return trip and then buy the ticket. I flew Emirates from Sydney and Ukraianian International airlines from Dubai.

I found it $1251.70 here are the facts FZO728 Wed29 May 13 14:45 Boryspil International Airport 4hr 50min
