My situation was slightly different, but I had an extremely frustrating experience with Qantas when I first qualified for Gold, and flexibility is not a word I would use in association with anyone from Qantas that I dealt with concerning this issue.
I've been a QFF member for about 7 years, but never travelled enough to even make silver until a couple of years back. My review date is 30 November, and I did a fair bit of domestic travel in the couple of months before that date in 2010. Something like 10 segments, but only about 200 SC as it was basically all MEL to SYD or ADL. Anyway, I went back to zero SC on 1 December per the rules, frustrating but fair enough. Then I travelled RTW in business in the first week of Jan. Took me straight past 800 SC. However, even though I flew MEL-SYD-SFO on QF on the way out, and then LHR-SIN-MEL on QF on the way back, that only gave me 3 eligible segments, as the LHR-SIN-MEL flights were all on one flight number. And all of the other flights were with BA or AA. And per the (bizarre) rules, LHR-SIN-MEL in business doesn't count for any more (in terms of eligible segments) than discount economy from MEL-ADL.
So at this point, I had flown on at least 14 Qantas flights and amassed about 1000 SC in the space of about 4 months, and despite the bad luck of the timing of my review date, my current SC balance was over 800, yet I was still on Bronze!! I then had to travel to Brisbane in Feb, so I knew that would finally get me upgraded to Gold. I thought I'd phone up in advance to explain the circumstances in the hope that I could get into the Club before these flights, but I got told no go, I have to wait until I have been credited for that one extra sector. Tried again at the airport on the day, but same result. However, they said as soon as I land in Brisbane I will get the credit and be upgraded to Gold straight away, so I can use the Club on the way back. But that didn't happen, and again I was refused entry to the Club despite my attempts to explain the situation. They did call the QFF helpline and put me on, but whoever I spoke to basically just said tough. Even though they knew I had now flown the required number of eligible segments and far exceeded the SC threshold. I made a complaint after I got back, but all the guy said was basically sorry for the inconvenience, but rules are rules. Now, even though I have been QFF Gold for almost 2 years and have requalified through to next Nov, I don't exactly go out of my way to travel with Qantas.
