Not sure I fully understand the comment about pound signs and accountants. The A330 is late coming out of refit, so they needed a few days of cover with a different plane.
Sorry, but pretty much all airlines have to do this at some time or another, even BA with a much bigger fleet. bmi have a limited set of planes to shuffle around, so keeping it down to a few days of cover doesn't seem unreasonable.
I'm probably missing something here, so feel free to educate me if I am
