I surely hope they're busy working to integrate the systems right now. Not sure if I remember correctly, but sometime ago you cannot submit online miles request for other OW carriers except CX/KA themselves. Now you can do it for BA and QF. Seems like system integration takes a long time (or is it just a side benefit of switching to Amadeus?)

I also just recently noticed that bookings on BA show up right away on my MPC upcoming flights. It seems a bit more integrated now after so many years, but I'm not sure if it was always like that and I just didn't notice.
