£650 million losses over 4 years must make bmi the the UKs most unsuccessful airline ever!
I would hardly say bmi was unsuccessful! To of being around for so long they obviously did something right. Yes unlucky in regards to fuel prices (like everyone else), Middle Eastern destinations, bad decision making at times & yes they've lost hell of a lot of money. I wouldn't exactly say they were unsuccessful though.
NOW Airlines & UK International Airlines springs to mind!
