I note your comment that an Easyjet base would never happen at BHX. This has puzzled me for a long time. They have bases at other UK airports where the general competition is similar (Ryanair, Jet2, Tui, even legacy carriers and in the recent past Monarch etc. the combination changing a little by location) and I've never understood why they ignore such a big airport (apart from BFS and GVA)? I think from your comments you may have the answer because I can't understand why this is, and I've never seen any proper explanation, maybe you can enlighten me?
