Here’s the short answer for getting from Incheon Airport to Hongdae: take the AREX All-Stop Train — about 55 minutes direct from Terminal 1 to Hongik University Station, ₩4,950 with a T-money card, no transfers. A taxi runs 45–70 minutes depending on traffic and costs several times more.
I’ve made this exact run once a year for two decades, usually off the back of a ten-hour flight from Sydney, and the train still wins almost every time. Below I’ll walk through each option — and the few situations where I’d skip the AREX entirely.

Main Route Options from Incheon Airport to Hongdae
“Before choosing your route, you can also check the official visitor information from the Seoul Tourism Organization:
👉 Visit Seoul Official Travel Guide
1. AREX All-Stop Train
🎫 If AREX is already your route, booking the ticket before you fly saves queueing at the machines with your bags still on you — the lines build fast when two flights land together.
The AREX All-Stop Train is the most balanced option for travelers seeking comfort, predictable travel times, and a reasonable fare. This train stops at every major station between Terminal 1, Terminal 2, and Hongdae (Hongik University Station), taking around 55 minutes.
During my flights back from Sydney or Melbourne, I always preferred the All-Stop Train because of its dedicated luggage racks—something I wished Australian trains would adopt more widely. Korea’s transit system tends to consider long-distance travelers, making the journey feel smoother, even when you’re tired from a long-haul flight.

2. AREX Express Train (Transfer at Seoul Station)
The Express Train runs nonstop from Incheon Airport to Seoul Station, cutting travel time slightly. However, since Hongdae isn’t a stop on the Express line, you need to transfer to Line 2 at Seoul Station.
In my experience, this option works best when you want to avoid crowds and get into the city quickly. Transfers in Korea are generally well-marked, but after spending over 10 hours on a plane, even well-designed stations can feel overwhelming. Compared with Australia—where major stations often have fewer multilingual signs—Korean stations feel more intuitive, but still require some alertness.

3. Seoul Subway (Line 2 Transfer Route)
Technically, you can skip AREX and use regular subway routes to reach Hongdae, but I don’t recommend this for first-time visitors with luggage. Seoul’s subway network is massive, fast, and reliable, but also busy and complex.
When I first moved to Australia, I was surprised at how uncluttered rail maps looked compared to Korea’s. Seoul’s network is efficient but can be visually overwhelming to new travelers.
4. Taxi or Airport Taxi
If convenience is your top priority, a taxi is by far the easiest choice. The journey takes approximately 45–70 minutes, depending on traffic.
There have been days when I landed in Korea physically exhausted from long flights across the Pacific, and a taxi felt like the only sensible option. Korean taxis are significantly more affordable than Australian airport taxis, especially over long distances. If you’re traveling with heavy bags or as a family, a taxi may actually be the most efficient option.
Step-by-Step Guide: Taking the AREX All-Stop Train
Buy Your Ticket
Follow the blue AREX signs after exiting the arrival hall. Ticket machines support multiple languages and accept most international credit cards. If you already have a T-money card, you can simply tap in without buying a separate ticket.
One thing the route apps won’t warn you about: Hongik University Station has nine exits, and the wrong one adds a sweaty ten minutes with your luggage. My exit-by-exit Hongik University Station guide shows which one matches your hotel.
Don’t have a T-money card yet?
A T-money card makes subway, buses, and even convenience store purchases far easier.
Where to buy it at Incheon Airport:
- CU convenience store (Arrivals Floor, both Terminal 1 & 2)
- 7-Eleven (Arrival Hall exits between Gate 5–7)
- Airport Metro Station vending machines

Board the Train
Each train car includes luggage racks and space for large suitcases. One cultural difference I noticed between Korea and Australia is how willingly passengers make room for travelers with bags. It creates a more welcoming environment, especially when you’re coming straight from a long flight.

Arrive at Hongik University Station
Hongdae is directly accessible from the AREX line. Once you arrive, you’ll see multiple exits leading to the nightlife streets, cafés, dessert shops, and indie boutiques. If you’re carrying bulky luggage, use Exit 3 or the dedicated elevator near the platform.

Landing after midnight with a jet-lagged family? That is the one time I skip AREX entirely — a pre-booked private airport transfer with the driver already waiting beats any train timetable.
| Transportation | Travel Time | Luggage Convenience | Cost | Best For |
|---|---|---|---|---|
| AREX All-Stop | ~55 min | High | Low | Most travelers |
| AREX Express + Transfer | 45–55 min | Medium | Medium | Faster arrival |
| Local Subway | 65–80 min | Low | Low | Budget travelers |
| Taxi | 45–70 min | Very High | High | Comfort seekers |
Travel Tips From Experience
Time Your Journey
Late afternoons and Sunday evenings are noticeably crowded. One advantage Korea has over Australia is train frequency—AREX departures are predictable and frequent, reducing long waiting times.
👉 Seongsu-dong is the neighbourhood I now build my Seoul trips around — Seongsu-dong Seoul Travel Guide: The Neighbourhood I Keep Coming Back To is the guide I put together after years of visits, covering how to actually make the most of it.
Use Local Navigation Apps
Google Maps is unreliable inside Korean subway stations. KakaoMap or Naver Map performs far better for transit navigation. In Australia, Google Maps dominates daily life, but in Korea, local apps are essential.
Avoid Overpacking
Hongdae’s lively streets are not ideal for dragging huge suitcases. After one exhausting arrival from Melbourne years ago, I learned that packing light—or taking a taxi—makes a world of difference.
Cost Breakdown for 2026
• AREX All-Stop: Budget-friendly, consistent schedule
• AREX Express: Slightly higher cost
• Taxi: Highest cost but unmatched comfort
If price is your priority, choose AREX. If comfort matters most, choose taxi.

Hongdae to Incheon Airport: The Trip in Reverse
Going back is the same trip mirrored. At Hongik University Station, follow the AREX signs down to the Airport Railroad platform — you don’t need to backtrack to Seoul Station first. The All-Stop Train runs straight to Terminal 1 in about 55 minutes for the same ₩4,950 on T-money, with Terminal 2 a few minutes further down the line.
The part travelers underestimate is timing. I plan to be at Incheon at least three hours before an international flight, which means leaving Hongdae a good four hours ahead once you count the walk to the platform and the ride itself. Check the last-train time in KakaoMap or Naver Map the night before, too — airport-bound trains thin out late in the evening, and missing the final one turns into an expensive taxi ride.
If you’re hauling suitcases out on a weekday morning, allow a buffer for the lifts and escalators — Hongik gets commuter-busy from about 8am, and the AREX platform sits several levels down. Off-peak, the ride back is calm enough that I usually spend it finishing the snacks I panic-bought at Olive Young the night before.
Korea vs. Australia: What to Expect as a Traveler
Having traveled frequently between both countries, I can confidently say Korea offers a smoother airport-to-city public transit experience. Korean signage, bilingual announcements, and short train intervals make navigation easy.
By contrast, Australian airport trains—while clean and well-managed—tend to have lower frequency and fewer luggage-friendly compartments. Travelers who expect Australian-style layouts may be pleasantly surprised by Korea’s efficiency.
FAQs
Is the AREX All-Stop Train safe for solo travelers?
Yes. It is clean, monitored, and safe even late at night.
Can I use a foreign credit card for ticket machines?
Most major international cards work. If not, cash counters are available.
How long does it take to reach Hongdae?
• AREX All-Stop: ~55 minutes
• Taxi: 45–70 minutes depending on traffic
Should I book the AREX Express in advance?
Reservations are optional. Same-day tickets are generally available.
Is Hongdae a good area to stay in?
Absolutely. It’s trendy, lively, walkable, and directly connected to major subway lines.
How do I get from Hongdae to Incheon Airport?
Same two options, reversed. AREX All-Stop from Hongdae Station takes ~55 minutes to the airport, or a taxi runs 45–70 minutes depending on traffic. Buy your ticket at Hongdae Station itself — no need to backtrack into Seoul Station first. Give yourself at least 3 hours before an international flight.
💡 Unnie’s Tip: Arriving tired or with a group? A private airport transfer drops you right at your Hongdae accommodation for a fixed price — worth it when you don’t fancy figuring out the AREX transfers after a long flight.
Once you’ve made it in from the airport, this is what’s waiting — a 60-second taste of Hongdae’s weekend buzz.
Final Thoughts
Finding the best route from Incheon Airport to Hongdae depends on your comfort level, luggage size, and energy after landing. After years of flying back and forth between Australia and Korea, I still find the AREX All-Stop Train to be the most efficient and traveler-friendly choice. However, if convenience is your top priority, booking an airport taxi straight to Hongdae can make your arrival far smoother.
This airport run is only chapter one. The rest of moving around Korea — subway lines, KTX day trips, buses and taxis — is mapped in my full Korea transport guide.
For everything beyond the airport run, you can plan the rest of your trip with my Korea travel guide.
The short version: take AREX unless you are landing late or hauling a lot of luggage, and have your subway basics sorted before you fly — the routes above cover both.
Need a faster, door-to-door ride?
If you’re carrying heavy luggage or arriving late at night, booking a reliable airport taxi is the most comfortable way to reach Hongdae.
