A TATL route operated by CO/UA, DL, US or AA would work from Liverpool but considering it's proximity to MAN I cannot see it happening any time soon.
Bradford has probably the largest (% wise) Pakistani community in the UK - an EK A332 would probably work from LBA! Yet again I cannot see it happening when they are clearly falling deeply in love with MAN.
MAN complains that LHR takes it's passengers yet MAN takes a hell of a lot from LBA, LPL, GLA, EDI, BHX, EMA etc.
