The multi city is still giving the cheapest of each class. So no way to book a Flex Plus? I usually fly to Dubai for a few days, then to a third country in the area (sometimes BAH, sometimes KWI) and then back home. Sometimes I fly from ALG or CMN to DXB and then I return to MAD. I am sure I am not the only one doing stopovers or travelling to different destinations. Or is there a way to do it and I haven't found out?
