I'm looking at booking a trip on AP.

However, the number of miles needed for this trip is less than it should be according to the mileage chart (i.e., J-class only requires the Y-class mile amount).

I can get to the final payment page and still it shows the erroneous amount of points. If I book and pay the fee/taxes...what are the chances I get to fly J for the points of Y?

Any one ever have a similar experience?
