Top tips for finding a cheap flight to South Korea

Plan to buy tickets in the Goldilocks Window

Over years of watching the cost of airline tickets rise and fall with what seems like no predictability, we’ve noticed that there actually are some patterns. There’s a period before every flight when you’re most likely to get a good deal on a ticket. It’s 1-3 months before a domestic trip and 2-8 months before an international one. We call this sweet spot the Goldilocks Window.

It’s important to note, though, that some trips require you to book even further ahead to get the best deal. If you’re traveling during the high season, for example, or over a major holiday—even if you’re just limited to specific travel dates with no flexibility at all, you’ll want to add a few months to the equation above. And, whatever you do, try to book before airlines raise prices as a flight nears, which happens 21, 14, and 7 days before departure.

Try the Greek Islands Trick before you book

Sometimes, you get lucky with a killer airfare deal from your home airport to exactly where you want to travel. Most of the time, though, you either have to pay more for your flights or get a little bit creative with your travel planning. Instead of booking that expensive ticket, we recommend trying one of our favorite travel hacks: the Greek Islands Trick. The gist is that you look for the cheapest flight that gets you close to where you want to be and then look for a different transit method (like a train trip, short flight, or drive) to travel the rest of the way.

If you’re trying to get to South Korea from Los Angeles, it might be a little disappointing to find that flights to Seoul are $1,100 and up roundtrip. Zoom out on the map just a bit, though, and you might discover flights from LA to Bangkok are less than $800 roundtrip. Even when you buy a separate flight from Bangkok to Seoul for $180 roundtrip, you’re still saving a little bit of money. These itineraries do require more attention to detail when planning, but sometimes the savings can make that attention worth your time.

Consider flying from a different departure airport

Whereas the Greek Islands Trick is all about trying different arrival airports to find a better deal, this tip is about comparing departure airports for cheap flights. People who live near more than one airport probably already do this, but it’s a good habit for any budget-conscious traveler to get into. We see fabulously low fares from airports all over the country, big and small, so it never hurts to browse a few options before you click that buy button.

When you live in a massive metro area like New York, it can feel like you’re spoiled for choice with three big international airports nearby. And, chances are, most of the time, you’ll find a great deal from one of them. But nonstop flights from NYC to South Korea might be $1,500 roundtrip or more, while flights from LA could be just over $1,000 roundtrip. There are often fares from New York to LAX with a price tag of under $200 roundtrip, which means a savings of a few hundred bucks.

Plan trips when it’s cheaper to fly

This sounds like obvious advice, right? Well, it’s a little more nuanced than it seems. This tip is all about flexibility. The more flexible you can be when you’re planning a trip, the more money you stand to save. That’s why so many frequent travelers prefer taking holidays in the shoulder seasons rather than the (more expensive) high season, for example. But not everyone has the luxury of that kind of flexibility—school schedules are what they are, and there’s no getting around that. Luckily, there are still a few things you can do to save a little bit when you fly.

You should check out fares in the first two weeks of June and the last two weeks of August if you’re stuck with summer as your only vacation time. These weeks often have cheaper airfare than the rest of the summer. You can also take advantage of Thanksgiving for international travel—it tends to be a pretty cheap week to fly outside the US since everyone is trying to fly domestically. You should also try to avoid scheduling flights on the most expensive days (Fridays and Sundays), aiming for what are usually the cheaper days (Tuesdays, Wednesdays, and Saturdays) instead.

Sign up for airfare alerts for specific trips

One of the best ways to stay on top of the constant changes in airfare without spending all your free time staring at the computer is by signing up for fare alerts for the trip you’re thinking about. Once you do that, you’ll be notified via email when the fare drops. Do this well enough in advance and you’ll be able to book with the confidence that you’re getting a good deal. Just note that you’ll need to set up a separate alert for each itinerary, so if your plans are flexible that means creating a few alerts. Or?

The busiest airport in South Korea is Seoul’s Incheon International Airport (ICN), which is a hub for Air Premia, Air Seoul, Asiana Airlines, Jeju Air, Jim Air, Korean Air, and T’way Air. There are a total of 78 airlines serving Seoul, with dozens of daily nonstop flights from 14 airports around the United States. It’s the only South Korean airport with direct flights from the US.

Frequently asked questions about flying to South Korea

When is high season in South Korea?

In South Korea, there is a high season in the summer (July-August), when foreign visitors have to compete for space with locals on their annual holidays on the beaches or in the mountains. Summer weather can be hot and oppressively humid, especially in the cities, which is one of the main reasons residents flee to cooler destinations.

But the country can be even busier during what is otherwise considered the low season of winter (November-January) since that’s usually when the Lunar New Year falls. This is a massive event in South Korea, with festive crowds in the cities and the countryside (not to mention adding considerably to the traffic situation). The other major nationwide holiday is the Harvest Moon Festival, which usually happens in September. Both of these holidays are tied to the lunar calendar, so be sure to check on the exact dates before you start planning a trip.

When is the best time to visit South Korea?

Weather-wise, the shoulder seasons of spring (late March through mid-May) and fall (September-October)—both temperatures and humidity levels are far more agreeable than they are in summer.

There are other reasons to visit South Korea in the shoulder seasons, though, that aren’t tied to the weather forecast. Spring in South Korea means cherry blossoms, whereas fall means colorful leaves. Buddha’s birthday occurs in early May which is celebrated in Seoul with the beautiful Lotus Lantern Festival. And one of the biggest holidays on the South Korean calendar (the Harvest Moon Festival, or Chuseok) usually falls in September—so you should either book well in advance or try to avoid the festival dates entirely to steer clear of the crowds and higher prices.

How many airports are there in South Korea?

South Korea has more than a dozen passenger airports, but there are three in particular that see most of the passenger traffic. The biggest and busiest by far is Incheon International Airport (ICN) in Seoul. In fact, it’s among the busiest airports worldwide, as it’s an important hub in Asia. Most of the flight deals from the US to South Korea that we find are flights to Seoul.

The second-busiest passenger airport in South Korea is Gimhae International Airport (PUS) in Busan, followed by Daegu International Airport (TAE) in Daegu in third place. These cities are both in the southeastern part of the country, and neither has nonstop service from the United States.

Which city in South Korea is the easiest to get to?

Seoul, South Korea’s capital and most populous city, is the easiest to reach because of its busy international airport, Incheon (ICN). There are nonstop flights to Seoul from 14 airports around the US, so there are usually lots of flights to choose from when you’re planning your trip. Even if your home airport doesn’t have a direct flight to Seoul, chances are good that you’ll still be able to put together an itinerary to get there with only one layover.

What are the rules for traveling with pets to South Korea?

Travelers who want to bring a pet with them on a trip from the US to South Korea should consult the USDA’s website for all the specifics since the rules vary a bit depending on the type of animal you’d like to bring.

For traveling with a dog, for instance, you’ll need to have documentation that the animal is current on its rabies vaccinations and is microchipped. The microchip certificate must match the name and number, as well. You’ll also need to obtain a health certificate issued by a veterinarian that’s been accredited and endorsed by the USDA. If everything is in order, there’s no quarantine period. If anything is missing, however, your dog will be quarantined at your expense.

And be sure to check with your airline, too, for their rules regarding flying with pets.

How long is the flight to South Korea?

Flights from the US to South Korea are long, so if you can get a direct flight to avoid layovers that add hours to an already tiring travel day, that’s the best-case scenario. The longest nonstop flights from the US to Seoul are from the East Coast—flight times of 15.5 hours are the norm. But even though the West Coast is closer to South Korea, you’re still going to be in the air for a long time. Nonstop flights from Los Angeles to Seoul are around 13 hours, and from Seattle, they’re around 11.5 hours.
