No i am afraid that this is regularly happens to me usually at least one of my sectors will fail to post automatically. i called the BAEC on this and was told that it is got to do with a BA/IB codesharing issue which something troubles their system and hence fails to post at the moment i am waiting on a IB coded EI flight to LHR to post to my BA account, i sent in the online missing form about a week ago so i am goona cal BAEC to confirm receipt and that everything is in order
the last time my DUB-LHR posted but my BA flight on a IB ticket didn't it took nearly three months to post and it posted as a BA flight from LGW instead of LHR-AGP so will see what happens to my EI flight soon
BTW all BC's had my BAEC number on them
