Made my sides ache with that one. I have seen lots of ways to loose money in aviation over the years but this one just about takes the biscuit.
It could have a chance on some routes but no way on domestic and definatley not on MME LHR. With regards to LCY, if they did manage to get a 737 in there without breaking it, the only way they would get it out again would be on a barge.
