Regarding PIA, if BHX and LBA are under the axe I'd bet on LBA going first. But who knows, I don't think they've got a clue what they're doing.
I can't see EK launching a 3rd daily at BHX anytime soon. I'd guess that BHX will follow the same pattern as MAN and have an A380 on the lunchtime service. I think a third daily service with any aircraft type would be too big an increase. But if PIA do go, someone has to pick up the slack. Do Turkish have the spare aircraft to upragde BHX or go daily?
