Now it seems they do NOT expire?
I stopped using LQ because of the points expiration even when you had stay activity but when I went to use the rest of my points today, I saw this on the website -
Points never expire as long as your account remains active
And according to the terms and conditions -
Members who do not have any stay activity within an 18-month consecutive period may be removed from the program and all accrued points will be forfeited.
This will be a welcome change, since getting at least one stay a year would not be a problem.
