Today, Alaska Airlines announced daily, nonstop service between its Seattle base and Toronto. The roughly 4-hour flight will be flown using the Boeing 737-900 aircraft.

Here’s a look at the route:

SCROLL FOR MORE

Route	Departs	Arrives	Frequency	Aircraft
Seattle – Toronto	6:50 a.m.	2:30 p.m.	Daily	737-900
Toronto – Seattle	3:40 p.m.	5:55 p.m.	Daily	737-900

Toronto becomes the sixth city in Canada served by Alaska, following Calgary (YYC), Edmonton (YEG), Kelowna (YLW), Vancouver (YVR), and Victoria (YYJ).

“We are very excited to welcome Alaska Airlines to Toronto Pearson. Their service to Seattle will provide much-needed capacity to the market and enhance customer choice,” said Kurush Minocher, Executive Director of Customer Experience and Airline Relations at Greater Toronto Airports Authority. Minocher also noted that the new route would simplify travel to the West Coast, Alaska and Hawaii.

Bottom Line:

Alaska will join Air Canada in flying a daily route between the 2 cities. That airline flies between Seattle and Toronto twice daily, typically on the Airbus A220-300 aircraft.

How to Book

This route is now live and is available on alaskaair.com for booking.

If you’re traveling this fall, cash rates are on the more expensive side, starting at $209 one-way.

We would recommend using Alaska Mileage Plan miles, as award tickets on this route are dirt cheap.

For dates this fall, we’re finding awards as low as 10,000 miles one-way (plus $6 in taxes). That’s a steal, especially considering how expensive cash rates are.

Update:

Alaska Airlines has switched to a distance-based award chart. Many of these rates have since increased.

Alaska Mileage Plan miles are the highest-valued airline miles out there. They are worth a whopping 1.6 cents each, according to Upgrade Points’ monthly valuations. Here are some ways you can earn Alaska miles for travel on Alaska or its many partners:

Through welcome bonuses and spending on Alaska co-branded credit cards
Transferring points from Marriott Bonvoy at a 3:1 ratio
Transferring Bilt Rewards points at a 1:1 ratio
Referring a friend for bonus miles
Shopping through the Mileage Plan Shopping portal
Mileage Plan Dining

Final Thoughts

Alaska has launched a new route from Seattle to Toronto. This route will make it much easier for travelers to visit either city or connect to other destinations such as Hawaii. While cash rates aren’t the cheapest, the low award redemptions make this route a sweet spot with Alaska miles!
