Dear FarWest
Thank you for your email.
I would like to inform you that any tier points earned by you, over and above the 30 tier points required to maintain your gold membership during your current renewal cycle, will not be counted towards your next renewal cycle.
If you require further assistance please contact us.
Thank you for your loyalty to the Flying Club programme.
Kind Regards
I'll see what BA service is like these days. With a Virgin strike threatened, it is probably safer to book elsewhere at the moment.
