Very strange - I've just had an email from BA with "Your executive club PIN", giving me a PIN saying Welcome to the club, and indicating blue status. I just logged into my 'old' / normal account to check and it's still there, gold as usual, on the same email address. I did have an avios.com account, no avios CC, and no avios in the avios.com account for years. So all very strange. No BA club number, just the PIN, so I can't even login to look at it....
