I do this frequently and will have the phone agent take over and book the ticket for me right then and there - including the eVIP and the whole 9 yards. As EXP, you never pay booking fees on your own PNR so no harm having them do the whole thing for you.
I've noticed that me being in the record online while they are in the record causes some issues so I just leave it all to them. Drink a few more in J on the way over and back (and in the FL) to make up the difference - and chalk it up to experience.
