"A bit tangential, but I don't pay any surcharges on short-haul MH flights I redeem with my BA Avios under their Rewards Flight Saver RFS rules."
AFAIK, RFS redemptions are only available on BA flights. If Avios redemptions on short-haul MH flights do not have surcharges, I suspect it is because MH cash fares on those routes do not have a surcharge component. Nothing to do with RFS.
