I've got a weird thing showing on a booking in MMB, not exactly to do with fare class, but with the calculated Avios being awarded. We're both Gold, booking is in a mix of J and A. Booked through AA. BA + AA metal.
My Name
Rewards for this booking: 70,722 Avios | 780 Tier Points
OH's Name
Rewards for this booking: 55,568 Avios | 780 Tier Points
My Avios is the correct one if I go and total it up in the Avios calculator. I'm not too concerned in that if the full 70k doesn't post I'll follow it up then, but I just can't work out where the 55k number comes from.
