I’ve just been erroneously bumped from Gold Guest List to Gold. I had well over 3000 tier points, several of them from the BA Holidays double tier points and even got the “you have retained Gold Guest List” message. However the expiry date didn’t update post tier point collection year expiry. Thankfully the GGL took my call and could see the tier points being taken from my account, and hopefully it will be resolved, but still slightly worrying as there is no way I could ever re-qualify for GGL from scratch.
