Andrew-how did you know about this 'C' fare? ITN does not show every fare , that's one of the problems with it!

CP should just display J class on its availability. C Class is reserved for 'discounted' fares in Business like the OneWorld fares, and 6J class seats does not 6C class seats left.

If CP quoted you the C class discounted seat, then I'd take their word for and go for it. Good gosh - I had forgotten how expensive fares had become within North America - in economy class yet!

The roundtrip in coach is almost as expensive as a Business Class ticket from Sydney to London (return) on Qantas/Air France !
