Tips for this route
- American, Delta, United and Southwest all fly SEA to YYC 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 Tuesday averages 16% 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.
- At 452 miles this is a short hop of 1h 30m, so an early-morning departure, which is usually the cheapest and most punctual of the day, costs you little sleep.
Destination guide
Calgary: The gateway to Banff and the Canadian Rockies
Most people fly to Calgary to get to the mountains, and that is a good reason: Banff is 90 minutes west and Lake Louise about two hours. The city itself has a strong food scene, the Stampede every July, and North America's largest urban pathway network.
Best time to visit: June to September for hiking and the warmest mountain weather, with the Stampede in the first half of July. December to March for skiing at Banff Sunshine, Lake Louise and Norquay. May and October are the value months — fewer people, and the scenery does not care.
