I followed the link and received this response:
We’re sorry, but there was an error in directing you to this promotion.
The reason for this error could be:
Apparently, I'm not eligible. 50,000 points would put me much closer to LTP.
How terribly frustrating, allleisure. If you'd like, I can have our team look into this for you and see if we can get you enrolled in the promotion. Just send me your Rewards Number and we'll get started.
