Just for information guys. Even with the new system, it is highly advisable to check that the number you've been credited is correct. Since April 1st, everything was correct for me until this trip to BKK on AF/KL. The e-ticket receipt was telling I would earn 17,180 miles for this trip and this was matching perfectly with the price before taxes +YQ. But I was credited "only" 16,996 miles. So I was missing 184. You'll tell me that's not a lot. Yes, but no reason to not claim it. A mile is a mile
I sent an e-mail to the Ulti TA and they credited me the 184 miles a few hours later ^, telling me that it was one specific tax that the system didn't take automatically into account.
So take home message : check your miles credit.
For the record, I am posting the different credit I received for this 4 leg trip. Funny to see how they can differentiate the contribution of each leg (my booking fares were J/Z/I/J).
