My understanding is it is not an automatic right at 3,500 points. I got invited on to the list after having 3 consecutive years of achieving 3,500 points. However speaking to a CSD on a flight he mentioned that this was probably not the sole reason as qualificatiion is based on a number of other factors, including the number of years as a gold card holder, (18 in my case) usual class of travel and of course ultimately the amount of money spent with the airline. Regular long haul premium travellers being the target! The CSD also mentioned membership of the GGL was restricted to less than 1% of the BAEC membership. So my understanding from the conversation, there are no hard and fast rules and no automatic right to get on the GGL and you don’t get there only by hitting a tier points threshold. It’s by invitation.
