I had a very similar experience. I had been a QFF for 15 years, mostly Gold, Platinum for about 5 years and P1 for a year. Just got annoyed with the slapdash domestic customer service in the 2000s, and the difficulty getting international reward seats once I slipped out of P1, having secured LTG years before. Wrote to Virgin HQ and asked for a Platinum match 5 years ago. Am now one of their top 5% travellers. Only fly Business, service and food is now excellent and reliable (after a few bumps a few years ago), and do most of my international flying with SA. The domestic lounges aren't the grandest, but they're perfectly serviceable. I wrote a "breaking up" letter to Qantas as I changed over, suggesting that I was exactly the kind of customer they should retain (I own my own business and only fly Business Class domestically and only First internationally) - never heard back from them. Have never looked back. I would give Qantas a Net Promoter Score of 4.
