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

Book in the Goldilocks Window

It might seem like the best time to buy flights would be at the last minute, when airlines need to fill seats. But we’ve found that’s not the case. In fact, we recommend booking 1-3 months before your trip or 2-8 months before an international trip. Not too close, not too far away, just perfect for deals. We call this the Goldilocks Window.

Of course, some dates are set in stone. Maybe you’re traveling for a wedding or home for the holidays. In those cases, when you can’t be flexible with your dates or are traveling in peak season, we suggest booking even further in advance. For winter holiday travel, start looking for flights in July. We’ve found prices are almost guaranteed to rise a month out from a flight, so whatever you do, try to book before that.

Use the Greek Islands Trick

If the place you want to fly is expensive–like many Greek Islands are–look at flights that get you in the vicinity. Say you want to fly from Seattle to Santorini in August, but tickets are astronomical. Try flying to London or Berlin instead, then look for a cheap flight to the island. Of course, this doesn't only work for islands. Try it for any popular destination.

Look for the cheapest flight that gets you close to where you want to go, then buy a separate flight, train, or ferry ticket (which is sometimes a fun way to see a new place) to reach your final destination. The Greek Islands Trick is a bit trickier logistically but can save hundreds of dollars.

Search nearby—and not so nearby—airports

If you live in Seattle, you probably think there aren’t many other big airports nearby. But hear us out: consider looking around the country.

If you live in Seattle, it might sound silly to look at flights out of San Francisco, New York, or Chicago. But, sometimes, other cities have insanely good deals that make a $200 connecting flight worth it. Think deals like $63 from Atlanta to Chile roundtrip. Or $202 from Los Angeles to Japan. For that price, we’ll take the extra leg.

Fly when it’s cheaper

As with most of the world, summer is a peak season for travel. “It’s all about summer vacation,” a SEA spokesperson said recently. “As soon as schools are out, we see the rush of traffic step up.”

When more people are traveling, prices will be higher. Try instead to fly during shoulder season, the time between peak and low travel times when the weather is still likely nice wherever you’re visiting, but the crowds have slowed. We’ve found shoulder season is the best time to save money, along with off season. If you have the flexibility to travel in the off season you’ll find cheaper flights and also see what touristy destinations are like devoid of crowds.

If you have to fly during peak season, try to fly on Tuesday, Wednesday, and Saturday, which are the cheapest days to fly. Friday and Sunday are usually the most expensive days.

Set alerts for specific trips

One of the simplest money-saving tricks when travel planning is to set a flight alert for your dates and destination, which you can do on Google Flights. You’ll get emails when your itinerary price drops, so you can book when prices are low without having to check them yourself every day. If possible, set up alerts months before you travel to have the best chance of scoring a great deal.

Seattle-Tacoma is the main hub for Alaska Airlines and one of the busiest airports in the country, hosting flights from more than a dozen airlines. This means you have plenty of options for travel. There are nonstop flights from SEA to more than 100 destinations.

How early should I arrive to Seattle-Tacoma International Airport (SEA) before my flight?

Airline guidelines typically recommend arriving at the airport two hours before a domestic flight. For international trips, they recommend three hours or sometimes even longer, due to extra security checks, customs, and the fact that more people check more baggage for international trips. But do you really need to be there that early? It depends on a few things.

How big is the airport, and where is your gate? Seattle-Tacoma is busy and large. The train between terminals takes about 5 minutes.

Are you checked in? Most airlines won’t allow you to check-in after a certain point, typically typically 30-60 minutes before departing. This is where checking in online comes in handy. Sometimes you can’t check in online, and in those cases you should make sure you arrive before the cutoff window.

Are you checking luggage? Airlines also have a stop point where they will no longer accept luggage, usually 45-60 minutes before a flight.

How busy is the airport? Seattle-Tacoma is one of the busiest airports in the country, with an average security wait time of 17 minutes. But if you’re traveling around a holiday, during summer, or on busier days like Friday and Sunday, it can be much longer. At these times, it’s better to err on the side of arriving early.

At the bare minimum, it’s wise to arrive at Seattle-Tacoma at least one hour before your flight, but 1.5-2 hours is a safer bet on most days. During peak times, 3-4 hours in advance may be necessary. The airport itself recommends two hours for a domestic flight and three hours for international flights.

How far is Seattle-Tacoma International Airport (SEA) from downtown Seattle?

Seattle-Tacoma International Airport (SEA) is about 14 miles from downtown Seattle, depending on where in the city you’re departing from.

What are the different transportation options for going from the city center to Seattle-Tacoma International Airport (SEA)?

There are several options for traveling from Seattle to SEA.

By taxi or ride share: Downtown Seattle is less than 20 miles from the airport, and you can get there by car in about 20 minutes with no traffic, though we suggest allowing at least 30 minutes at most times. Costs range from about $40-$50, depending on demand.
