You dont honestly think PIA will choose to expand at LBA when their prime routes to the US are about to be axed, the A310s are on there way out and the majority of regional routes ex UK will be routed with TK thru IST.
GLA was announced just a few months ago as being profitable and continuing, its an age old promo ploy
Despite the news reports, I could honestly see LBA being closed due to its proximity to MAN. Its far easier for them to route the pax through MAN rather than a 2 weekly A310 operation. Its unfortunate but it seems to be the way everything is going.
Whilst they are more likely to keep it for the local population, I wouldnt be totally surporised to see BHX go but TK increase, due to it being sandwiched between LHR/MAN.
As for MAN, its obvious the KHI/JFK route is going, but wouldnt be surprised it TK goes either double daily or A330/A340 mix, even with ISB/LHE still served from MAN, either that or PIA will continue to operate all of ISB/LHE/KHI on its own metal.
