The old bmi group management really had a habit of chopping and changing routes. In the time I was there, Warsaw, Budapest, Milan, Rome, Madrid, Nice, Malaga, Zurich, Bergen on shorthaul (not to mention routes operated on behalf of Star Alliance) , Washington, Chicago, India on longhaul - each new route requiring millions of pounds of setup costs, and being abandoned with no real attempt to market it or compete.
I remember at one stage a senior operations manager expressing frustration because (in effect) everything was too profitable for the A330 at the time - in effect, they needed more aeroplanes, but the company had no intention of investing in anything else. The aim never seemed to be to grow, but to finesse what they had to maximise revenue from it.
