For an upcoming trip LAX to Toronto (which I am planning to take this May, and planning to fly economy), I am confused about:

1. To buy a discounted economy ticket (costing me $275 - $310), or
2. Use 25000 AA miles (of which I have many).

I did a search, and found that many readers here value miles at round 2c/m, a few at 1.25c/m. So the 25K award valued at 1.25c/m would relate to $312.50.

Am I thinking in the correct direction?

Thanks in advance.
