A great experience, excellent for foreigners visiting Korea.

Such a great promotion of 1+1 and very easy to redeem.

The train ride was smooth, fast, and clean. The voucher price on the app was good, but they should provide more detailed instructions on how to redeem the voucher, as the website only has instructions in Korean.

This is a great deal if you're looking for a cheap and convenient way to travel from Incheon Airport to Seoul and vice versa. The route from Incheon Airport to Seoul is very convenient and easy to find. The route from Seoul to Incheon Airport is a bit complicated, with no specific directions, so you should leave early to avoid missing your flight.

Super convenient, cheaper than buying tickets directly at the kiosk, great value for money. The Arex train significantly shortens travel time from the airport to Seoul Station, highly recommended.

Easy to get tickets at the machine, the train runs very punctually and safe. 👍🏻

Very convenient. You can use a QR code to enter the train, plus in-town check-in is eligible.

Using this voucher is really economical, the road to AREX station is so long that I'm almost late in Incheon.

It's great, you should definitely buy it! Changing tickets is very easy, and it's cheaper than buying at the airport. You can tick your ticket 30 minutes in advance, so be careful not to rush. I tried changing my ticket through the app but couldn't tick it, and I thought I had to print a paper ticket, so I used another one and lost one ticket – what a shame! Please take note.

Easy to scan barcode and get the tickets!

Very easy to redeem and worth it.

Very comfortable and clean! We had to make a reservation first, then find the ticket machine and enter the booking code. The ticket was printed immediately.

You can redeem and book your schedule easily via Arex website.

Easy to use, just exchange your ticket at the machine. The train seats are very comfortable.

Okay, it's quick to get there but a bit hard to find, and there are scheduled departures, so be sure to go early to catch your flight or you might miss it.

Comfortable, clean, no hassle, try to check the departure time before arriving in Incheon.

Good option to travel from/to airport.

Very easy commute to Seoul during peak time.

Easy to redeem at the ticket machine at the train station.
