HI Oli
I see your point - but Jet already have that operation set up in BRU - they do all their India - Europe - North America routes hubbing through BRU at the same time, and are interlined with BD for UK regional flights including EMA.
I totally agree with other posters that EMA does need an AMS flight with a KL code or a CDG with an AF code to provide fully connecting worldwide services.
Will be interesting to see if the arrival of Donington Park on the International GP calendar, and the year-round conference facilities that the Park have plans to build will affect EMA's success at attracting AFKL.
