I just sent an email to BA about a similar thing actually. I am still awaiting a reply.

I have two bookings -

1) The first booking is a CE (Restricted) cash booking EDI-LGW-PFO-LGW-EDI and it is showing as generating 120 tier points. Shouldn't this generate 160 tier points? 60 for each of the CE sectors and 20 for each of the domestic sectors?

2) The second booking is a WT+ (Restricted) cash booking MFU'd to CW EDI-LGW-ATL-LGW-EDI and it is showing as generating 150 tier points. Shouldn't this generate 190 tier points? 75 for each of the WT+ MFU'd to CW sectors and 20 for each of the domestic sectors?

Surely all of these domestic sectors should have booked into tier point qualifying fare buckets based on the purchasing options selected (all above Economy Fully Flexible) on ba.com?

Thanks!
