About flights to Republic of Korea
Korea draws a striking mix of inbound traffic. With 267 non-stop international routes landing across 14 airports, this isn't a country you have to route through Tokyo or Hong Kong to reach anymore. The bulk of arrivals come from regional neighbors — China alone accounts for 70 routes, Japan another 63 — which tells you something about who's actually showing up: a lot of business travelers, a lot of short-haul tourists doing a quick cultural reset, and an increasingly serious wave of K-culture pilgrims who've done their research and know exactly which neighborhood they're heading to before the wheels touch down.
Why visit Republic of Korea?
The short answer is that Korea rewards specificity. Seoul is the obvious draw — finance, tech, food, nightlife — but the country has genuine regional personality if you're willing to look past ICN. Busan has a coastline that makes other Asian beach cities look overproduced. Jeju is an island that actually earns its UNESCO designation rather than just coasting on it. Autumn (late September through November) tends to be the sweet spot: manageable crowds, sharp mountain colors, and temperatures that don't punish you for walking around. Spring brings cherry blossoms and the associated tourist surge, particularly from Japan. Winter is underrated if you're into skiing or just prefer paying reasonable hotel rates. Business travel clusters around Seoul, with the financial and tech sectors keeping midweek flights consistently full year-round.

Tips for travelers heading to Republic of Korea
If you're flying from the USA, all 15 of those non-stop routes feed into ICN — which is the right airport for Seoul, and frankly one of the better-run facilities in the world once you're actually inside it. Heading to Busan? Look at PUS (Gimhae International) directly; it saves you a four-hour train ride from Seoul and the fares are often surprisingly competitive. Jeju is CJU, and primarily serves regional connections. Korea operates on the Korean Won — cards are widely accepted, but have some cash ready for smaller restaurants and markets. Most Western passport holders get 90 days visa-free, but check current entry requirements before you book.
