Have to disagree about Matt's Planet, I would describe myself as an average (mean not median) FTer and if it wasn't for his videos I wouldn't be contemplating an RTW. I mainly only review the BA forum with some EI and AA from time to time, I only visited the Oneworld forum for the first time a couple of months ago.
After the slicing and dicing of the BA FF club, significant numbers of the club were left without a clear cost effective path to gaining premium status. Matt put together several videos - which he earns a living from - on the various Oneworld options to regain status. It appears that Finnair+ is generally the best option. I have looked at the Finnair website and it is nowhere near as eloquent as Matt has been!
