Speaking of "minor" destinations, BA has one return daily flight London to Kiev (used to be LGW-KBP, now LHR-KBP) on 737 or A320 aircraft. They provide access/invitations to an airport-provided business class lounge. And as a OneWorld Emerald FF flying on an economy award ticket, I was given invitations for myself, Mrs NM and 3 x Mini-NMs to use the lounge.

So if BA can provide the in a once-a-day services port, why not QF/BA/CX in somewhere like BOM?
