Congratulations to Marriott Rewards program for being ranked #1 on the very popular travel website THEPOINTSGUY (TPG).
I have shared a link below for people to easily find and read. They also rank the best rewards program for airlines. Keep in mind that everyone's situation is different and in my case, I get upgraded on over 90% of my flights with USAirways and American Airlines so my perks are much better based on my airline status with these two. I think a couple days ago, I posted an article where it provided various rewards points values and that generated a very good discussion as well where some folks shared how they valued their points and accrual methods.
Best wishes and I am glad I am part of a #1 team for a change! WHOOOHOOOO!!!!!!!! Phil
