I just flew from LAS to LGW with BA on an AA flight number and my avios were posted, but to my surprise the amount of Tier points was 0. I checked this in the calculator and this is correct according to it. Flying with an AA number from LAS to LGW on any booking class (lowest economy, economy, business or first) generates 0 tier points. I called the BAEC line and they confirmed this. Can anyone else confirm this?
