RE: bmibaby mega expansion

bmibaby have said that they are going to operate 11 Boeing 737-300 Aircraft. 9 for East Midlands and 2 For Cardiff. However, on OAG.com, it shows that bmibaby operates the Fokker 100 on a lot of routes and the 737-500 on a few and the rest are 737-300’s. Very weird and confusing!
