Amnesia,
Which airliner is it which has a return flight to dubai for QR 540? I checked with emirates and qatar airways, the prices were 1090 and 780 riyals.. 540 riyals would be a pretty decent, don't know why they charge so much just to Dubai. Also, if you're 3-4 people going in one car, traveling by road turns out to be cheaper that way I guess..
