First of all, remember that the Great Circle mapper, as handy as it is, is really only a 'rough and ready' guide. Note their warning:

You should download the *A Round the World Mileage Calculator, which will give you the offical *A distance for each sector.

I was quoted 'Star2' for a plan of 29008 a couple of years ago. I don't know if it's possible for a human being to cut you any slack, or if it's all down to the computer.

Are there no flights from western Canada to Cuba? If not YVR, check YYC.

I believe that (at least some of) the SYD-YVR flights are non-stop.
