Easy to redeem. Cheaper than kiosk.

Quick and super cheap - the discounted price was a dream. You pay the same as for all-stop trains, but this with much better service.

Great and easy redemption at the self-service kiosks! Very convenient and cheap.

Very good for the punctuality of the departure schedule and there was an officer who helped us to exchange the train tickets, thank you.

Very good in terms of ticket exchange, and the train also left on time.

It's so convenient to use this voucher after buying them. Saved me a lot of time and money. Great to buy from app! Highly recommended 👍

Easy to use, just go to the ticket machine at the airport or Seoul station.

Must buy before you go to Seoul. Easy to use, just go to the ticket machine for the Arex train, scan the barcode, and follow the instruction. Then you will get a ticket.

I hope you to don't fix the date.

Ticket redemption is easy. Find the ticket machine, scan the barcode or enter the barcode number from the voucher, and the machine will print out the ticket.

Easy to use and cheaper than actual. Next time I will buy it from app.

Great and efficient redemption, can just scan the QR code at the ticketing vending machines! Easy to use and also much cheaper using promo codes and stuff

Arex was a great choice to travel from Incheon Airport to Seoul Station. Efficient, comfortable, and affordable.

Simple, easy, and convenient. I went alone, went straight to the ticket information, received a ticket, and just went.

Easy, superb, convenient, efficient, great, cheap.

Convenient, I often go to Arex, buy 1 get 1 free is very ok.

Good service, easy to change tickets. Convenient to the airport.

The redemption was easy. It could be done at the station. However, you might not get the departure time that you want if it is peak hour. The train journey was smooth and on time.

All is good. On time, the train was clean. The easy and fast way to airport.

I have tried booking, but only one leg. It is easy to use and the price is good, but I have to wait and see if I can book the other leg.
