Assuming Gold in BA flying C to LHR - each flight is 5540 Avios
for NYC C reward you will need 65000 Avios (and this is with 0$ addition)
? BA has that fuel surcharge, which I believe is still bigger than LY's.
Since LY doesn't have a real US credit card, you have to rely on HAS/Amex, which put a business class flight at 160-200k comparable points to the east coast (vs 120~140k on US competitors).
