Strangely enough, I made a SYD/PER return booking on Boxing Day for myself and my girlfriend. I am a Qantas Club Bronze member, while she is a Bronze Frequent Flyer. During the booking process, I entered both our numbers but when the tickets were issued, only my FF number came through on my ticket and hers did not display on her ticket or come through on her "My Bookings" section.
As mentioned above, the situation was corrected with a quick phone call to Qantas.
Then, last night, I made a booking for just myself from SYD/BNE ... put my number in the booking but normally the flight displays in the "My Bookings" section almost instantaneously and this time it did not appear. I received the ticket this morning, only to find no FF number displayed on the ticket and the booking still not in the profile.
So, who knows?? Maybe it has something to do with the volume of people booking tickets on this latest sale (which I see has been extended a day)??
