Probably this would be one of the most disappointing losses
in the last three years, as it is a niche route
Yes it is a disappointing loss, as I believe BHX-LYS was one of the few non Paris AF UK routes, and as you say its is especially disappointing that they didn't at least try it at daily before a total dropping.
As well as flybe being a potential candidate for replacement, maybe a route for bmi baby to pick up, as bmi regional offer it from MAN and they don't even have much of a base there.
