I earned platinum elite lifetime status in 2013 or 2014 and was issue the lifetime card. However, I received a platinum premier elite card with expiration of 2/2016 this year and my online status changed. Does this mean the lifetime card is now invalid (no difference in membership number)? Does "lifetime" status have a limited life or has the program terminated lifetime status?
no it doesn't expire but I think they send you a card now that you are PP. If you drop back you will likely get the lifetime back. I didn't get a lifetime card until I no longer earned platinum based on nights stayed.
