I thought if you used miles or SWUs to upgrade you still earned miles on the orginial ticket purchase.
Am I correct? I'm expecting to earn 150% MQM on the upgraded leg because the ticket was in S or W at booking.
But the way some online info I've read makes it sound. This O class ticket will earn 0 MQM. What's actually going to happen?
Thanks all.
You will get the miles corresponding to original purchase: AF prem Eco: 150% MQM and 125% RDM, regardless of upgrade or not.
After over 7 round-trips TATL, AF prem eco purchased either on DL or AF ticket and upgraded to O (or not upgraded, once when AF banned upgrades last summer), I never had any issue getting the right mileage credited less than 24hr after each flight.
