MK Airlines did indeed operate a combi service out of Nairobi in the early and mid-1990's but I heard were run out of town by British Airways. They also carried multiple pax on charters etc. I understand that they opted to focus on cargo. And from what I recall, the Icelandic AOC they held sometime ago is used by a pax operation. Who knows though: maybe they are preparing for the collapse of Air Zimbabwe ???. Great airline and even greater people, I hope the G reg works for them
