I was in the exact same situation as you. International award reservation in first, called to add lap infant, paid the fee, got the confirmation number. It took a week and 3 phone calls in order to get the ticket booked. It was in queue for that entire time. Now, my son shows up on my reservation. Although they mistakenly added JR at the end of his last name, since I have a JR at the end of mine. I called to correct and they said there is no way they can change it.
