About the Jeju → Seoul route
Jeju to Seoul GMP is one of those routes that tells you a lot about how a country moves. At just 452 km and roughly 32 minutes in the air, this isn't a flight so much as a very fast elevator between two completely different worlds. You've got Korean Air (KE) on one end of the spectrum and a pile of budget carriers on the other, which means the cabin mix is pretty wild — retirees heading back to the mainland, Jeju-based workers commuting, and the odd tourist who somehow decided a short hop beats the ferry.
Why travel from Jeju to Seoul?
Jeju is Korea's island escape, and Seoul is where everything else happens. People make this trip for reasons that stack up fast. There's family — a lot of Koreans have relatives split between the island and the capital. There's the pull of Myeongdong for serious shopping and street food that Jeju just can't replicate. There's business, because despite Jeju's growth, the real meetings still happen in Seoul boardrooms. And honestly, after a week of hiking Hallasan or eating black pork barbecue, Seoul's Han River parks, late-night pojangmacha stalls, and the sheer scale of a city like this hit differently. The contrast is the whole point.
