About the Seoul → Istanbul route
Seoul to Istanbul is a proper long-haul commitment — just under 9 hours 20 minutes and nearly 8,000 km of westward flying. Three carriers operate this route: Korean Air (KE) and Asiana (OZ) on the Korean side, and Turkish Airlines (TK) holding down the other end. TK in particular treats this route seriously, which makes sense given Istanbul's position as one of the world's great hub airports with over 300 onward connections. The passenger mix skews toward leisure and cultural tourism, though you'll find business travelers heading to Istanbul's financial and trade corridors too. It's not a brutal flight, but it's long enough to care about your seat.
Why travel from Seoul to Istanbul?
Istanbul pulls Korean travelers in ways that are hard to pin on a single thing. The historical density around Sultanahmet — the Hagia Sophia, the Basilica Cistern, the Grand Bazaar within walking distance of each other — rewards the kind of methodical sightseeing Korean tourists tend to do well. Turkish food has also developed a genuine following in Korea over the past decade, and experiencing it in context (proper lahmacun, fresh simit, a decent glass of çay on a Bosphorus ferry) lands differently than the Seoul approximations. There's a growing Korean expat and business community in Istanbul tied to manufacturing and trade sectors. And for travelers who want Europe-adjacent culture without European prices, Turkey consistently delivers on that front.

Practical tips for ICN → IST
April through June and September through October are the sweet spots — Istanbul's summers get genuinely hot and crowded, while winters are grey and occasionally disruptive. Korean citizens currently benefit from visa-free entry to Türkiye for stays up to 90 days, but confirm this before you fly since bilateral agreements shift. IST is a vast airport; clear immigration, collect bags, and budget time. The Havaist bus to Taksim runs frequently and costs a fraction of a taxi. Bring some Turkish lira for small purchases — card acceptance is wide but not universal. Flying westward, jet lag hits your mornings harder than your evenings, so plan the first day light.
