I just called the OPSC and they also told me my ticket number was not valid for the flights I flew on 6/25! The agent eventually found my flights and said the miles would post tomorrow. The reason for the missing mileage she told me was the fact the ticket had more than 4 flights...and the ones that didn't post were flights 5 and 6. I'm not sure I believe that...I regularly have complex tickets that post fine.
