Any newer data points on this? I am flying on 12/21 ATL-LHR, then on 12/24, LHR-DEL. The ATL-LHR leg will get me over the hump to Diamond and I'd like to earn the bonus for the LHR-DEL leg. If that won't happen, should I be Diamond by 12/31 for my return flights, DEL-LHR and LHR-ATL?
My tickets were bought on VS's website and all flights on my itinerary are VS coded.
