It is funny to see how so many people know what Flydubai should do...
I guess they have their own management with their own ideas , so unless you have the power to change their mind or if you work for them all what is said here is not worth a penny...
Let's see what their plans are but all I know is that they don't even have received all the B737-800 they have on order , so I don't expect to see anything like a long haul aircraft for a long time...
