Double daily minimum or pointless really. But this KLM story seems to be BHDs old chestnut that wont die. I dont think I will hold my breath on this one or TK starting from BHD. When AirUk did the AMD before they pulled the plug even though all the flights full but them got such a small percentage cut in fare from onward carriers and especially northwest orient to to the states they pulled the route.
If it is marketed well the batyle will be BA vs KLM as they both after the onward business and high yield fares
