Why You Should Take a Flight to Seoul

South Korea’s capital seemingly a mass of contradictions. Home to 12 million people, Seoul is part futuristic metropolis and part bastion of tradition. You can step out of the crowds into a tranquil Buddhist garden, shop for eye-catching fashions and cutting-edge design in a deeply conformist society and dine on traditional Korean dishes in state-of-the-art restaurants.

When to Book Flights to Seoul

Seoul has sweltering summers and freezing winters, and, for this reason, many people choose to visit in late spring or early autumn when the weather is mild and many of the city’s biggest events take place, including the lotus lantern festival, marking Buddha’s birthday, in May and the city’s fireworks festival in October.

Seoul’s summers are very humid and typhoon season lasts from June to September. If you don’t mind the cold and now, winter is a good time to visit Seoul. The city is relatively quiet and there is skiing in the surrounding hills.

How to Find the Best Flight Deals to Seoul

Planning ahead and having some flexibility are key when looking for cheap flights to Seoul. And when you book with Expedia there are several ways to ensure you find a bargain.

Most visitors arrive at Incheon Airport, but the smaller Gimpo Airport nearer the city also has international flights. Most flights from the UK require a change, so use the ‘Nearby airports’ option when searching to uncover different potential routes. The ‘Show flexible dates’ option shows the cost of flights on different days and can unlock different connections. You can filter your flight results by criteria including airline, connections, ticket type and cost using the Show options menu and buttons on the left of the search screen.

How to Get to and Around Seoul

Unsurprisingly, Incheon Airport has efficient links to Seoul. There are trains, high speed and stopping, limousine buses and taxis to the city.

Seoul itself has a world class public transport system, with an 18-line subway system and several different categories of bus. Purchase a contactless T-Money card to use them or buy tickets as you go.

Exploring on foot is a good way to see Seoul, but the streets can be very crowded and the city centre layout is confusing.

Most street signs and public transport information notices are written in Korean and English, but do not expect everyone you meet to speak English, especially cab drivers. It is worth writing your local address on a slip of paper.
