My advice to you is to not bother with e-mails... you have to call them to get it sorted out. Be diligent and keep logs of all your calls and what the agent says to you. Be ready to put the initial requests in and then call back 3 weeks later if (when) the flights don't post.
I have had flights on LH and SA this year with the following happenings:
- SA flights did not post at all, despite my FF # being on the BPs
- One LH segment posted entirely correct (Go figure!)
- One LH segment on the same ticket as the previous one and same fare class posted at 50%. Still trying to get this one fixed for 2+ months now.
All in all, I have had 1/4 partner segments automatically post correctly. The two SA segments have been corrected 15 days after calling in, but the LH segment at 50% is still a lingering issue after 2 e-mails and 3 phone calls that I will have to call back in again after another week or two.
