The market will dictate the outcome in the long run. The rise of the low cost carriers at the expense of the short haul operation is just one example of how all too sadly times have changed.
I recall the integration or lack of it from all crews not on the 737-400 at Dan Air. Remembr how you all stood up for the regional guys when the deal with Flybe was done.
Management are spoiling for a fight they know to be long overdue. To think that a solitary 757 will be used to test the resolve is quite interesting. if they were serious about their plans there would have been a full plan, secrecy until the exact launch and a full and proper integrated site...
