Great post Rutnan16 and couldn't agree more re. AI. Get DEL back to daily rather than an operator with no long haul experience and who would probably up sticks to LGW as soon as the slots are available...... Gulf Air are rumoured to be looking at long haul expansion as are Saudi. Both have potential at BHX (indeed Gulf Air very nearly arrived at BHX in the form of Gulf Traveller using 767''s to AUH but pulled out at last minute). Not so sure about Oman, they have struggled with MAN loads although they are improving now.
Off the wall, I wonder if Scoot would work to SIN? Surely enough leisure traffic to go round despite SQ ops at LHR and MAN?
