I did a DONE4 last year (which when I booked originally I was going to do myself) then later my girlfriend decided to come so booked a LONE4 for her (don't worry I copped it from every female I know)
Anyway, we were in San Fran at the time and in the morning I decided to check our flights for the evening to New York, noticed that I was flying out that night but my girlfriend was booked on the NEXT nights flight... don't know how that happened. Had a look myself and saw there were no seats in the same fare bucket that she needed to change onto my flight - I thought that it was going to be a real pain.
Rang Qantas - it took a whole of 5 minutes to have it sorted out. The guy originally said he couldn't do anything, but then he said "does she really need to be on the same flight" - I said it would be nice if she was so was. He went away again for 30 seconds and came back and said it was all sorted.
I assume I wouldn't have been able to have that fixed if I were gold/silver/bronze (or it would have taken a lot more effort)
*edit* err I left out the bit where I was able to get help this week*
I was able to discuss options with premium desk with no wait at all , again had heard stories from friends with massive waits on the phone lines. No issues flying from MEL-BNE yesterday
The top bit was meant to be an added story for the other time I think having status helped!
