When planning a trip to South Korea, most people automatically book flights into Incheon International Airport near Seoul. It’s the country’s largest international hub, has the most flight options, and is usually the cheapest choice for travelers coming from the United States or Europe.

But on our most recent trip, we did something different.

Instead of flying into Seoul, we flew from Japan directly into Busan, traveled north through South Korea, and then flew home from Seoul. After experiencing Korea both ways, I honestly think flying into Busan can be the better option for certain itineraries.

So… is it better to fly into Busan or Seoul? The answer depends on how you’re traveling.

How We Traveled Korea Two Different Ways

Our First Trip to South Korea

On our first visit, we followed the most common route:

Flew into Seoul Traveled all the way down to Busan Then had to go back up to Seoul to fly home

While the trip was still amazing, this route ended up wasting a lot of travel time. We were essentially backtracking across the country just to catch our return flight.

Our Second Trip (Flying Into Busan First)

On our second trip, we changed our approach:

Spent a few days in Japan Flew from Japan directly into Gimhae International Airport Traveled north through South Korea Flew home from Seoul

This route felt smoother, more efficient, and far less rushed. We were able to work our way up the country instead of repeating the same travel legs.

Why Most People Fly Into Seoul

There’s a reason Seoul is the default choice.

Incheon International Airport is South Korea’s main global hub and offers:

The most direct flights from the U.S. and Europe More airline competition, which often means lower prices Easier long-haul connections

For travelers flying directly from places like Florida (like us) or other parts of North America, Seoul is usually the easiest and cheapest airport to fly into. Busan simply doesn’t have the same number of long-haul international routes.

Because of this, many people don’t even realize that flying into Busan is an option—especially if they’re planning their first trip to Korea.

Why Flying Into Busan Can Make More Sense

Flying into Busan can be a smart choice if your itinerary includes more than just Seoul.

Busan is very well connected to other parts of Asia, especially Japan. Flights between Japan and Busan are short, frequent, and often affordable, which made it an easy decision for us.

Flying into Busan allowed us to:

Avoid backtracking across the country Travel in one continuous direction (south to north) Save time and energy End our trip in Seoul without rushing

If your trip includes Busan, Gyeongju, Daegu, and Seoul, this route feels much more natural.

Is It More Expensive to Fly Into Busan?

For most travelers coming directly from the United States, yes—flying straight into Busan is often more expensive or less convenient, simply because there are fewer long-haul flights.

However, flying into Busan can make sense if:

You’re visiting Japan or another Asian country first You’re booking a multi-city or open-jaw flight You plan to fly into one city and out of another

In our case, flying Japan → Busan → Seoul → home felt like a much better use of our travel days than flying in and out of the same city.

(Also, at the time flying to Japan was actually cheaper than flying into Seoul South Korea)

Busan vs Seoul: Which Airport Should You Choose?

Here’s an easy way to decide.

Fly into Seoul if:

It’s your first time visiting South Korea You’re flying directly from the U.S. or Europe You’re mostly staying in Seoul

Consider flying into Busan if:

You’re traveling from Japan or another nearby country You plan to visit multiple cities in South Korea You want to avoid wasted travel time You’re flying into one city and out of another

Neither option is wrong—it just depends on how you want your trip to flow.

Is Busan Worth Visiting?

Absolutely.

Busan isn’t just a convenient airport—it’s a destination on its own. With its coastal views, beaches, seafood markets, and relaxed atmosphere, it offers a completely different experience from Seoul.

Starting our trip in Busan made the transition into South Korea feel slower and more relaxed, while ending in Seoul gave us that energetic city experience at the end of the trip.

Final Thoughts: What We’d Do Again

If we were planning another trip that included both Japan and South Korea—or multiple cities within Korea—we would 100% fly into Busan again and work our way north.

Most people only talk about flying into Seoul because that’s the most common route. But depending on your itinerary, Busan might actually be the better airport to start your trip.

Sometimes the best travel decisions aren’t the most popular ones—they’re the ones that save time and make your trip smoother.
