Posting stats on Biz Extra is abysmal for British Airways flights. Had a number of BA biz flights in past months - only one trip posted properly. I did everything I could think of before the trip - call BA and have the numbers entered in by them manually; call Biz Extra before the flights; remind the BA agent at check-in. Just seems to be a structural error between Biz Extra and BA. If this messes up any of those juicy, juicy summer bonuses - there will be words.
