When ICN and GMP are booked out or expensive, taking the KTX to Busan (PUS) can save your trip and your wallet.
The "Incheon" Bottleneck It’s January. It’s "Seollal" (Lunar New Year) week. You check the flights from Seoul to Sapporo and the prices are $900 USD. Or worse, everything is sold out. The Reality: Most travelers only look at Incheon (ICN) and Gimpo (GMP). But Gimhae (PUS) in Busan has a secret network of flights to Japan that are often half the price. --- 1. The Strategy: KTX + PUS The Move: Take the KTX (Bullet Train) from Seoul Station to Busan.
It takes 2.5 hours and costs about $50 USD. The Connection: From Busan (Gimhae Airport), you can fly directly to Narita, Fukuoka, or Sapporo. The Math: Even with the train ticket, the total cost is often $200-$300 cheaper than flying from Seoul during peak periods. 2. Why it Works Busan caters more to the local Southern Korean market. During holiday weeks when Seoul workers are fleeing to Japan, the Busan flight routes often have more availability. Airlines: Check Air Busan, Jeju Air, and Jin Air. They run frequent "commuter" style flights to Japan.
3. The "Layover" Vibe Why not turn it into a 2-city trip? Yuki's Suggestion: Spend one night in Busan eating seafood by the beach, then catch your morning flight to the snow. It’s much more relaxing than fighting the crowds at ICN. --- Don't let a "Sold Out" sign at Incheon stop your trip. If the snow is dumping, take the train south and fly from Busan. Use Google Flights and set your origin to 'PUS' (Gimhae) to hunt for these hidden deals yourself.
