The Big Shift: Asiana Airlines Moves to Terminal 2

If you have flown through Incheon before, you probably remember Asiana Airlines being the king of Terminal 1. Well, those days are over. Following the finalization of the Korean Air-Asiana merger, all Asiana flights shifted to Terminal 2 on January 14, 2026. This is a massive update because Terminal 2 has now doubled in size thanks to the Phase 4 expansion project.

I’ve seen a few confused travelers lately, so please double-check your ticket. Terminal 2 is now the primary hub for the “Hanjin Group” family, including Korean Air, Asiana, Jin Air, and Air Busan. If you are flying with Jeju Air or T’way, you will likely still be at Terminal 1. The new T2 extension is gorgeous, featuring massive LED media walls and a lot more green space, so if your transfer is there, you’re in for a treat.

Step-by-Step: Navigating the 2026 Transfer Process

Once you land, don’t just follow the crowd to “Arrivals.” Look for the green “Transfer” signs. The process is generally smooth, but the scale of the airport means you need to stay alert. Here is the local breakdown of the flow:

• Security Check: All transfer passengers must go through a security screening on the 2nd floor. Keep your liquids in a sealed duty-free bag if you bought them at your departure airport.
• The IAT Shuttle: If your incoming flight is at T1 and your outgoing is at T2 (or vice-versa), you must take the Intra-Airport Transit (IAT) train. It runs every 5 minutes, but the total transit time—including walking—can take about 20 minutes.
• Transfer Counters: If you don’t have your next boarding pass, head to the 4th floor of either terminal. The staff there are incredibly helpful and speak great English.

Comprehensive Directory: Transfer Facilities & Amenities

Knowing the exact location of service desks and lounges is key. Many of these facilities fill up quickly, so advance reservation is mandatory for hotels and highly recommended for premium lounges.

Where to Sleep: Comparison of Nap Zones and Hotels

If you have a long overnight layover, you have several options. For the hotels, booking weeks in advance is essential as they stay at 100% capacity.

• Nap Zone & Relax Zone (T1/T2): Located on the 4th floor, East and West sides. These are free, open 24/7, and offer reclining chairs. No reservation needed.
• Capsule Hotel Darakhyu (T1/T2): Located at the Transportation Center, 1F. Open 24/7. Advance reservation required. Call: 032-743-5000 (T1).

Freshening Up: Shower Rooms and Hygiene

Shower facilities are free for transfer passengers.

• T1 Showers: 4F near Gates 25 and 29 (05:00 – 23:00).
• T2 Showers: 4F near Gates 231 and 268 (05:00 – 23:00).

They provide towels and soap, but it’s best to bring your own specialized skincare.

How to Spend Your Time: 3, 5, or 10-Hour Layovers

Depending on your clock, here is how I recommend spending your layover time at ICN. Important: Exiting the airport requires a valid visa or K-ETA. For detailed eligibility, see the K-ETA visa rules for visiting South Korea.

• 🕒 Under 3 Hours: Explore the Digital Gym in T2 or try free crafts at the Culture Center.
• 🕒 5 to 6 Hours (Songdo City):
  • Transport: Taxi is best (20-25 mins, ~40,000 KRW). Alternatively, Bus #303 (40 mins).
  • Details: Visit Songdo Central Park for water taxis and the Hanok Village. It’s the safest independent trip for a shorter layover.
• 🕒 8+ Hours (Seoul City):
  • Hongdae: Take the AREX All-stop Train (55 mins) for street food and shopping.
  • Gyeongbokgung: Take the AREX Express to Seoul Station (45 mins) + 15 min Taxi. Only recommended if you have 8+ hours.

📌 Local Note: Always aim to be back at the airport 3 hours before your departure. Traffic in Seoul can be unpredictable!

Local Insider Tips: Smart Pass and Tech Perks

To really travel like an insider, download the ICN Smart Pass app. Register your face and passport to skip the long lines at transfer security—it uses facial recognition so you can breeze through.

Also, don’t worry about staying connected. The “AirportWi-Fi” is fast and free. In the new T2 expansion, almost every seat now includes wireless charging pads and USB-C ports, so you can keep your devices juiced up effortlessly.
