I've done the Flybe/Emirates route to DXB twice in the last 3 years, so its not a destination I go to very often. They didn't cover themselves in glory first time around. Believe it or not they managed to lose my luggage (tagged all the way through) between MAN & DXB. All other aspects of the transit & travel were fine. Second time it all went OK. And I guess if it's an oft used route then it's quite a good service.
I agree, it's the add-on's and transfer aggro that make some trips both expensive and tiresome (especially for someone of a certain age like me!).
