- American, Delta, United and Southwest all fly YYC to SEA nonstop, so compare the total with bags before picking the lowest base fare: the difference between a basic and a standard economy ticket is often less than one checked bag each way.
- Departing on a Wednesday averages 14% less than a Sunday on this route. If your dates are flexible, shift the outbound by a day or two and check the calendar view before you book.
- Book 6 to 12 weeks ahead; fares climb in the last three weeks and around holidays.

Destination guide
Seattle: Coffee, mountains and Puget Sound
Seattle is the Pacific Northwest's gateway: Pike Place Market, the Space Needle and ferries across Puget Sound, with Mount Rainier and the Olympic Peninsula a couple of hours away. Sea-Tac is a Delta and Alaska hub with light rail downtown.
Best time to visit: July–September is dry, sunny and gorgeous — and the most expensive. May–June and late September are good compromises. October–April is gray and drizzly but cheap.
