I've been spending lots of money in my small corporation and accumulating hundreds of thousands of AM EX points (Gold). Now I've bought 1 airline trip and 1 Broadway show show ticket but they seemed to take an extreme amount of points. So, duh, is there a general formula? With airlines you just follow a chart with miles to dollars but this does not make sense and seems "expensive"--for instance $250 item for 58,000 points.
