Hi there Devine Wind,
the first flight is QR 482, so Istanbul. Are you at the end of the workingday, so DOH - IST - DOH, at home or will you stay in Istanbul and then going to DOH, an do the flight 110 (Dubai)?
I doubt it is:
Day 2: DOH - IST - DOH (Total of 9 to 10 hrs I think)
Day 3: DOH - DUB - DOH (Total of 5 to 6 hrs..)
And then 3 days standby.. not the worst deal I think..?? Or did I something wrong?
