We'll have to rename mileage runs to dollar runs.

Anyone know how I can spend $50,000 to make plat with the least number of miles?

In all seriousness who is this frequent traveller that Delta is after? I don't really have any freedom to pick my carrier for work - I've always had to take the lowest (sometimes unrestricted) fare in the market. The only time this wasn't the case was when we had negotiated rates with our preferred carrier. In neither case did I have any personal influence on carrier selection.

I do have a lot of influence on my personal travel - always at low to medium yield fares. The question now is: how much influence do carriers want over this discretionary spending?
