Bringing in B757s to be operated by non-bmi mainline pilots for such a period(with possible extension according to the management) is wrong. We've had regional here for a few years now and they have proved to be the thin end of the wedge. BALPA should have put it's foot down on the regional issue sooner as the whole problem has now snowballed to a point where they don't know what to do about it. This kind of thing doesn't happen at our Heathrow based UK competitors because their pilots via BALPA don't put up with this kind of thing. How come BALPA when it comes to bmi are so weak?
