I would imagine that the first thing the new owners of Regional will do is change the name so as to distance themselves from any future BMI troubles.
Although the letter to BMI staff says that regional will keep the winter and summer 2012 schedules. I think that has been said to make the sale of other aspects of the group look more favourable.
I would suggest that some significant adjustments of the routes should be expected, before Summer 2012. Especially bearing in mind what Skipness One Echo said above.
Regional definitly has the Aberdeen market cornered but that is hardly enough to maintain a decent load on a fleet of 18 aircraft full time.
Will be interesting to see what occurs.
