Yes apparently Flybe are advertising for an Aircrew Manager at BHD so indicating a base, beginning to look like a crowded market from Belfast to he UK mainland with what looks like ending up with Flybe, Emerald and EasyJet plus BA to LHR from the spring.
At my local airport BHX it will mean Flybe and Emerald from BHD and EasyJet from BFS when as far as I can recall whenever we have had more than
two operators on a route ( popular bucket & spade routes apart) it ends up in tears - wait and see I suppose.
