I've booked a few flights with Expedia Canada, and each time I've been happy with the results and service Expedia offered.
Expedia Canada was one of the first and largest online travel websites to go online a few years ago. Since they launched, Expedia Canada has grown continually and is now one of the most popular and user-friendly places to book a flight online.
I've booked a couple flights with Expedia Canada (expedia.ca) and what I like the most is being able to search multiple airlines, and getting prices back in Canadian dollars. It's difficult to find travel websites that cater to the needs of Canadians, but Expedia.ca does a pretty good job!
I very much recommend booking with Expedia Canada. Check out their website here:
