- Prices: Cheapest flights to Seoul during winter months—up to 40% less than spring peak; book 4-6 weeks ahead for optimal savings.
- Weather: Cold -6–7 °C with crisp, dry conditions; only 3–5 snowy days monthly, far less precipitation than high season.

You could pay in installments without interest on your credit card, it would help even more!
Danielle J.
Kiwi kept me informed of the entire process. if they can check you in, they will. I was properly checked in for the outbound flight, but I had to do the return flight myself because this is how the airline in question works. return flight was slightly delayed and the gate changed. I was duly informed of all this. all in all, very satisfied with my booking with kiwi.
