As others have said, it’s 3000TPs for two consecutive years or 5000 TPs in one year to get Gold Guest List.
I have a Concorde Room Card as well as I get over 5000TPs per year which is nice but not a major benefit. It doesn’t equate to any higher tier within the Exec Club.
It has made no difference whatsoever to my upgrade frequency, which remains very low.
As others have said, it’s only the guaranteed redemptions which make the tier worth having. Otherwise I wouldn’t get too excited about getting to this tier. Even the card looks almost exactly the same as a regular Gold Card!
