The wide-ranging sale kicks off June 27 and will last through July 31, with discounts on flights to and from 11 destinations in Canada. That includes Montreal, Toronto, Edmonton, Vancouver, Ottawa, Calgary, Winnipeg, and Saskatoon.
Delta's promotional site says tickets start at $109 USD ($189 CAD) one-way for travel beginning September 5 up through December 20. However, at the time of publication, there are round-trip tickets available that run only $195 including fees and taxes. Though, like any sale, there's no guarantee the best prices are going to be around for long.
