About the London → Seoul route
London to Seoul is a proper long-haul commitment — 8,862 km and just over 10 hours in the air. That's a full night's sleep if you time it right, or a very long film marathon if you don't. Korean Air (KE) and Asiana (OZ) both fly this route direct from Heathrow, and Virgin Atlantic (VS) is in the mix too. It's a route that pulls in a real mix of travelers — K-pop fans, tech and finance types on business trips, and a growing number of UK foodies who've heard the hype about Seoul's food scene and need to see it for themselves.
Why travel from London to Seoul?
Honestly? Seoul is one of those cities that earns repeat visits. Gyeongbokgung Palace is right there in the middle of the city — ancient and completely unbothered by the skyscrapers around it. The Hongdae neighborhood is where I'd send any first-timer who wants to understand why Seoul's youth culture hits so differently. Beyond the obvious K-culture pull, there's a serious business corridor between London and Seoul — Samsung, Hyundai, and their supply chains keep a lot of suits on this route. And the food alone justifies the ticket. Real Korean barbecue, banchan you can't replicate at home, and late-night street food that exists entirely on its own terms.

Practical tips for LHR → ICN
Spring (April-May) and autumn (September-October) are the sweet spots — comfortable temps and generally lower fares than peak summer. ICN is huge but honestly well-organised; immigration moves faster than most airports its size. From the airport, the AREX express train gets you to Seoul Station in about 43 minutes and it's cheap. You'll need Korean Won — card acceptance is good but not universal at smaller spots. No visa required for UK passport holders for stays under 90 days. Jet lag hits westbound returns harder than the outbound, so plan an easy first day back home.
