USAirways offers up a rare opportunity to travel to Toronto, Ontario, one of North America’s most dynamic cities and the cultural and entertainment capital of Canada.

One-way trips of $190 are valid on Tuesdays, Wednesdays and Thursdays through Feb. 19, 2014. A two-week or more advance notice of travel is required. Compare this sale rate to $276 offered by most other carriers.

There are a number of blackout dates: June 21, 23, 24, 27; July 3, 7, 8, 18, 26; Aug. 12; Oct. 4, 13, 17, 20; Nov. 22 and Dec. 1, 2, 19-21.

USAirways serves Toronto with one connection in Philadelphia.

Buy tickets immediately (this deal has no ticket-by date).

Sale airfares are always subject to change. Every seat on every flight is not offered at the lowest rate.

I recommend starting the search for available seats at Kayak.com vs. calling an airline directly. You can also search for the sale at travel websites such as Expedia, Orbitz or Travelocity, etc.

Airlines can discontinue or pull a sale price without notice when the offer does not have a “ticket-by” date or when the offer is deemed “sold out.”

Book lodging online at the official website of Tourism Toronto, www.seetorontonow.com and, as an added bonus when you book a two-night stay, the third night is free. The web site also partners with shows and special events to bring affordable deals on a custom Toronto experience.

Consider a summer or autumn visit to the vibrant city of Toronto and then sip your way through many of the wineries of Niagara-on-the-Lake, a popular option to round out a weekend to Niagara Falls.
