BMI Regional
As many others have said this is excellent news. It does seem that the new management have really been working hard to move the airport away from focussing so greatly on one airline, and said airlines short lived BOH base arguably shows that the airport has been able to win a number of new carriers whilst still ultimately keeping the existing residents happy.
My earlier reservations about Flybe launching the route as well do remain however, although I do believe there are some other routes BMI Regional could maybe make a go of in the future, such as FRA, CPH, BRU and ZRH.
