Despite the appearance of CheapTickets.ca as a Canadian site, the prices are not quoted in CDN funds—it does not tell you this until you start the booking process.
We spent a great deal of time comparison shopping for our New York vacation and cheaptickets.ca was by far the cheapest until we realized it was in US funds. This does not make any sense they would quote this way other than trying to get shoppers hopes up that they are getting a great deal. We are using Expedia.c a from now on instead even if it is a bit more since they are upfront on their pricing.
Editors Note: We do agree that the pricing on this site can be confusing. We checked flight only and it was clear that the prices were in CAD. Then we checked hotel only and that was clearly in USD. The confusion came in when we checked the package deals (air and hotel) where no currency is listed until the final page where a reservation can be made and it is in USD.
