Earning Miles on Cash Upgraded Award Flight
I've got a multi-segment award flight I booked using my Aeroplan miles ( YYZ -> DXB on AC, DXB -> CAI on MS, CAI -> GVA on MS, GVA -> ZRH on MS and ZRH -> EWR -> YYZ on UA). I managed to get my MilagePlus Gold card entered into those bookings so that I can get *Gold access (I have no status on Aeroplan).
Is it possible to receive milage credit on flights that were upgraded via LMU/Bid upgrade? I know the AC segment from YYZ -> DXB won't since that will re-fares into R (which earns nothing per MilagePlus rules). However, I've upgraded paid flights on UA at last minute and it would re-fare into P (which would earn full milage). Would it work the same way with my award booking? Are there any nuances to earning miles on cash upgraded award flights?
Safe travels,
James
