I would suggest not to fly in Fly Dubai. First of all after u land in Dubai, You have to go to the separate terminal where is for flying to Nepal and Bangladesh and u wont be able to come back and roam to the other international terminal. So if your transit is long you will have hard time to spend your time. Second, They don't serve anything in the flight and you have to pay for it. Third, you will see lot of chiki people who thinks they are better as they can speak English. This was my previous experience during my visit to Nepal, where I paid $1825.37 for the two way ticket, while flying with Fly Dubai.
