I am a great supporter of BHX and regional air services but, there was one major problem with the route network that Maersk/Duo/BACON operated. Most were unprofitable or uncompetative due to both airlines high operating costs. This would explain why BA is no longer in the regions and Maersk UK/Duo are sadly no more.
The 50 seat high frequency jet service is no longer the money maker it was, due to increased fuel and duty costs and most low fares airlines operate aircraft that are too big (too many seats) to warrant daily service to what are essentially business destinations such as OSL, HEL, CGN, GVA, ARN, LYS etc.
I think that some of these services may not resume ex BHX for many years if at all.
There are things to look forward to at Birmingham and that there is any expansion at all next Summer is a real bonus in the present economic climate.
