Sorry to ask a question which may have been asked elsewhere ....... but how easy is it just to turn up at a travel agent or an airline ticket desk in, say, Montreal or Ottowa and buy an AONE6 on the spot for the Canadian$ equivalent of the locally published fare at the point of origin of the AONE6? If this is as simple as it seems to be for non-Canadians to do, then has anyone any recommendations as to a good agent or ticket desk where it can be done?
