Referring back to a previous thread, given the expansion of bmibaby at EMA and the fact that bmi are going to have to find new homes for a good few of those little junglejets, it would seem possible that at least one might find its way up the M1 to LBA.
An extra EM4 at Leeds? They've only recently added ORK and BRU, as well as added frequencies on the Scottish routes, hence the most likely new routes to Europe would probably be to Germany and, say, CPH.
Can you honestly imagine the LBA bosses trying to attract Ryanair to a Hahn route at the same time as bmi to a Frankfurt Main route?
