Top tips for finding a cheap flight to Seattle–Tacoma International Airport (SEA)

Buy plane tickets during the Goldilocks Window

We know that great deals on airfare can happen year-round. Experience has shown us, though, that there’s usually a sweet spot in advance of a trip when airfare tends to be at its best price. We call this the Goldilocks Window. For domestic flights, it’s 1-3 months in advance. For international trips, it’s 2-8 months ahead.

There are times, however, when you’ll want to book even before the Goldilocks Window. If you’re traveling during peak season or a holiday, or you can’t keep your travel dates flexible, we suggest adding a few months to the equation. Anyone who wants to fly home for Christmas, in other words, should book that trip in July. And be sure to book before the airlines raise prices at the last minute, which they often do 21, 14, and 7 days before a flight.

Check fares from different departure airports

People who live in an area with more than one nearby airport are accustomed to searching for deals on fares from all of them—just in case there’s a better price from an airport a little farther away from home. We see deals pop up in airports big and small all over the place, so we suggest considering other departure airports nearby as well as not-so-nearby.

If you live in the greater New York City area, you’ve got three major airports to choose from, so you might not think to cast the net any wider. But if you don’t, you might miss a better deal. Flights from Newark’s airport to Seattle might look good at $250 roundtrip, but that’s before you see there’s a roundtrip flight from Philadelphia for less than $160—and every bit counts in a travel budget (especially if you’re traveling with family). With so many deals appearing all the time, too, there’s every chance your next trip could be half what you’d otherwise pay for it just by flying out of a different airport.

Schedule your flights when it’s cheaper

As we know from those high school economics classes, high demand often leads to higher prices—and we know that’s true when it comes to airfare. The cost of a plane ticket during peak travel season or a holiday can be exponentially more expensive than for off-season flights. Flexibility when booking a trip is one of the main ways to travel more cheaply, not least because of the huge portion of every travel budget that airfare requires.

Not everyone can be flexible with travel plans, though. If you’re in that category, there are still a couple of things you can do to save a bit on flights. For summer vacations, look for cheaper fares right at the beginning (first two weeks of June) and the end (last two weeks of August). And schedule flights on the days when they tend to be cheaper (Tuesdays, Wednesdays, and Saturdays) and avoid the days when they tend to be more expensive (Fridays and Sundays).

Track specific trips with fare alerts

Constantly refreshing your browser to see if airfare has come down in the last five seconds isn’t sustainable—you’ll end up hating the trip before you even book a flight. Instead, sign up for airfare alerts and let technology do the work for you. When the fare drops into your target range, you’ll get an email notification so you know when to buy. Just keep in mind that if your plans are flexible, you’ll have to set up multiple alerts or sign up for a service like Going, which tracks all prices from your home airport.

There are 32 airlines serving SeaTac, which is a hub for Alaska Airlines (it’s Alaska’s primary hub) as well as Delta. There are 93 airports around the US with direct service to Seattle-Tacoma International Airport.
