Yes...I saw it. The way I understand it they were trying to find the person who had the biggest ff-mile balance. (That is the way I understood it...not who has earned the most, but who has the biggest balance...I could be wrong!)
They interviewed a guy (from Chicago, I believe?) who has a 25million balance with AA. I expected a "pudding guy" story or something but apparently he earns most of his miles the old-fashioned way...flying! They also interviewed a UA flyer who has a large balance (not 25m though). UA had named a plane after him.
It was just a human interest story about what it is like to fly that much and have that many miles available to use.
