Where can I find ZED mileage?

I am trying to plan a trip using ZED carriers, but ZED mileage is point to point and the airlines use circle route mileage on their websites. Does anyone know where I can find accurate mileage to figure out my fares (without calling the pass bureau again)?

Thanks.

I use webflyer.com.

I use farechase/ on Yahoo- it's a great way to find a variety of route and airlines and time tables all at once - you can click on the itinerary and see the mileage for each leg, and even eliminate things as you need to (ie stops,airlines etc). I used to use it when I was a regular Pax, and now have found it a valuable resource to see what options are available!
