Air Canada is trying to compete with WestJet’s current seat sale offer by having a popular U.S. destination seat sale until January 29th, 2015. Within this sale, you can fly to select one-way locations for as low as $190. The only restrictions on this offer is that you must book before January 29th at 11:59pm EST, and that some restrictions on what day you can fly may apply.
There is a limited number of seats available with Air Canada at these hot prices, so the price is subject to change. You’re best chances of finding deals on these one-way fares is to avoid popular travel times (e.g. holidays and long-weekends) and to try for travel days on Tuesday, Wednesday, Thursday or Saturday.
