KBW tips for this route

1Cheapest month right now: January 2027, from $141 one-way. For holiday dates (Lunar New Year, Chuseok, Christmas) book 2–3 months ahead; otherwise 4–8 weeks before departure is usually the sweet spot.
2You land at Incheon (ICN). Central Seoul is about 1 hour away: AREX express to Seoul Station (43 min), the all-stop AREX to Hongdae, or a limousine bus straight to hotels in Gangnam and Myeongdong.
3Coming for a clinic? Book the consultation for your first full day and keep the last day free. Ask the clinic how many days to stay before flying home after a treatment — our treatment guides list it too.
4Once the flight is set, KBW books the rest in your language on WhatsApp: stays, clinic appointments, restaurants and tours.
