There is nothing wrong with the Barbie Jet, which just a biz jet with a few extra seats, i am not sure its right for bmi in the present climate,IMHO i think Jim French made the right call with the Q400 21 extra seats, lower fuel burn and turboprop salaries, the sector block times on most of Regionals routes (incl the one's they run for mainline) are within 5 mins on either aircraft.
Interesting to see that baby are doing BFS-PRG this winter, not sure where the aircraft starts from (no based aircraft at BFS) and it won't position into do this, BHX and/or MAN aircraft would be my guess
