Its possible that flybe could make tracks into PLH via their tie-up with Loganair. The SAAB 340 recently made a few trips into PLH albeit with a reduced payload, but it did get in and out. The allowable payload may just be enough to justify PLH sectors over to NQY where a full load could then be taken to anywhere in the existing network - including a revised LCY sector.
I personally hope that BE dont take over the route. If they did I personally think you see prices rise, standard of service fall and routes cut. There are a few operators who may be interested in ASW.
T3 - If eastern where interested they would need to decide on whether to operate ASW as a seperate company or to intergrate it into T3. If they intergrated it into T3 they would then need to decide whether ASW becomes a full service carrier as T3 is currently or whether T3 move towards ASW's business model.
RE - As a low cost regional carrier RE already operate a fleet of ATR42's that can operate into PLH. RE is always looking to expand and the aquisition of ASW could help them to expand in the UK.
NM - An outsider. Manx2 have said they want to expand outside the IOM and purchasing ASW would allow them to do that.
SI or GR - If either carrier was looking to expand into the UK domestic market the purchase of ASW would give them a good basis to start with.
