if belgium decided to introduce an APD, Ryanair will never leave CRL same for CIA or BHX
You surely mean _will leave_, I mean instantly ? Sure, don't get us BHX folks started on our so-called FR-base. BHX these days is surely not a FR stronghold. The whole situation isn't so different from when they were at MAN (Lots of BE plus legacy carriers to their hubs and some longhaul), just that at BHX, they retreat slowly, not with a big bang. Should try NRN-BHX while it lasts.
