This is a very useful table. When the new ultra-longhaul (referred to as LH+ in the table above) category came up it was meant to be for Singapore, Buenos Aires and the Tokyo airports only as these were the >6000 mile trips.

However, MRU, JNB (flying from LGW) and CPT are all above this distance as well and seem to earn the higher tier points when you put it through BA's calculator e.g. 160TPs for CW. Not complaining but it seems like this was never official (or I missed it)
