It’s a question we get all the time. And while we have our opinions, we’ve never actually sat down and looked at the hard data. Today we’ll be looking at airfare to really determine when is the cheapest time to travel to South Korea.

We used Google Flights to pull estimates on 5-day, round-trip flights in 2024. As prices and seasonal patterns can differ by region, we looked at flights originating in California, New York, Texas, the United Kingdom, Singapore and France. We checked a few different airline booking sites to see how well they correlated and Skyscanner came pretty close!

General Thoughts
Generally speaking, early-December and mid-January before and after the holidays offer cheap flights with a few exceptions (France, New York). And, if you’re looking to save a100 USD here and there, you can opt for layovers in China or Japan (day trips in Japan are particularly fun if you can squeeze out about 12 hours).
