BHDflyer
Here in Toronto Porter Airlines are expecting to make money with a Q400 when Air Canada used to only use a -100. The difference being that with the extra puff in those PW150s the Q400 can probably do a couple of more daily rotations compared to the BA -300s, or take on sectors currently operated by the 145 in similar flying time.
As the Qs accumulate at Flybe the benefits of a larger fleet in terms of crewing and engineering will become apparent. BACON's mixumgatherum fleet should have been slimmed down long since - now Flybe will swing the axe for them.
Maybe with their relationship with Embraer a swap of some existing 145s - maybe as corporate/military conversions - plus the BA options in exchange for more 190s or 195s could happen?
