South Korea Travel: Seasonal Recommendations and Flight Booking Tips

South Korea has four distinct seasons, each offering a different charm. Since ticket prices and travel experiences vary greatly depending on the time of year, it is important to know the seasonal characteristics when planning your trip.



Questions and Answers about Booking Domestic and International Flights to South Korea on TICKETS.CO.KR

What is the cheapest way to book domestic flights within South Korea?

The cheapest way to book domestic flights in South Korea is to avoid weekends, public holidays, and peak season (late July to early August). Especially when booking domestic flights from Gimpo Airport, you can purchase tickets for less than the average price if you book at least four weeks before the departure date. TICKETS.CO.KR helps you find the lowest prices by comparing real-time promotions for Jeju Island flights and weekend special deals for domestic routes.

How can I find cheap international flights departing from Incheon International Airport?

To book cheap international flights departing from Incheon Airport, it is recommended to consider flexible travel dates and choose flights departing early morning or late evening. Furthermore, by setting up the price alert function on TICKETS.CO.KR, you can receive immediate information when special low-cost international flights from Incheon become available, ensuring you don't miss out on the cheapest tickets to Korea.

How do I set up a flight price alert on TICKETS.CO.KR?

On the TICKETS.CO.KR website or app, search for your desired route (e.g., cheap flights departing from Seoul), and then click the 'Set Price Alert' button located at the top or side of the search results page. This feature allows you to track real-time changes in flight prices to Korea, enabling you to receive notifications when the price reaches your desired range.

Which is cheaper, the Seoul-Busan KTX train or a flight?

The price comparison between the Seoul-Busan KTX and a flight varies depending on the time of year. Generally, the KTX maintains a more stable price range than flights, but flights can be cheaper if you take advantage of promotions offered by low-cost airlines operating the Seoul-Busan route. It is important to consider the travel time and total cost (including airport transfer time and cost) to make the best choice for your personal situation.

When is the cheapest month to travel to South Korea, and when should I book my flight?

The most advantageous months for finding low-cost flights to South Korea are typically January or February (excluding the Lunar New Year holiday) or November. These periods are considered off-peak, leading to lower flight prices. When using a Korean flight booking site, reserving 6 to 8 weeks before the departure date is the most effective way to save money on your Korean flight ticket.

How does TICKETS.CO.KR find flights at such low prices?

TICKETS.CO.KR is a flight price comparison platform. We collect and compare data in real-time from hundreds of airlines and online travel agencies (e.g., Hana Tour, Modu Tour, etc.). This allows us to instantly show users the cheapest prices among all available options, including low-cost flights to South Korea.

Does TICKETS.CO.KR add any markup to the ticket prices shown?

No. Airlines and booking sites actually pay us to be featured on our platform because the travel industry is so competitive. We do not add any extra fees or markups to the prices you see. The price you see is the final price provided directly by the airline or booking site.

Are there same-day special deals when booking domestic flights in South Korea?

Yes, same-day special deals for domestic flights can occasionally occur, primarily intended to fill remaining seats on the airline. However, same-day specials are very rare and difficult to predict, so booking in advance is the fundamental rule for buying cheap Korean flight tickets at a stable price.

What are the tips for finding the lowest price international flights departing from Busan?

To find cheap tickets departing from Gimhae Airport (Busan), you should check the list of low-cost carriers based in Busan and keep an eye on their promotions. Also, routes to Southeast Asia or Japan, which have many flights departing from Busan, are highly competitive, so compare the lowest prices by searching various dates on TICKETS.CO.KR.

What happens to domestic flight prices during the Lunar New Year (Seollal) or Chuseok holidays?

Comparing flight prices during the Lunar New Year or Chuseok holidays is crucial. Domestic travel demand surges during these periods, causing flight prices to peak. If you must travel during the holidays, booking quickly 3 to 4 months before the flight opens is the only way to potentially save costs.

South Korea Travel Guide: Essential Practical Information You Must Know

We have compiled essential information you should know before traveling to South Korea. Plan a more comfortable and enjoyable trip with practical tips on transportation, accommodation, culture, and more.

South Korea has an excellent public transportation system. In major cities like Seoul and Busan, subways and buses are the primary means of transport, while the KTX high-speed rail connecting major cities nationwide is fast and convenient. For Jeju Island or smaller cities, renting a car or using intercity buses is recommended. With a single T-money card, you can use most public transport. Compare the price and save time by choosing between the Seoul-Busan KTX and flying.

Accommodation in South Korea is very diverse. Major cities like Seoul and Busan offer a wide range of choices, from luxury hotels to affordable hostels. If you want a traditional lodging experience, we recommend a Hanok Stay. In Jeju Island or smaller local cities, pensions and resorts are popular. Especially if you are traveling using low-cost flights to South Korea, it is important to manage your accommodation budget efficiently.

South Korea is generally a very safe country. However, be cautious of pickpockets in crowded tourist areas. When using taxis, ensure the meter is running, and confirm prices beforehand at street food stalls or small shops. Walking alone late at night is relatively safe, but always be aware of your surroundings. In case of an emergency, call 112 (Police) or 119 (Fire/Ambulance). Travel insurance is essential for your peace of mind while abroad.

Respect for elders is important in Korean culture. It is customary to wait until the eldest person picks up their spoon before starting a meal. Be quiet in public places, and it is common to remove your shoes when entering homes or some restaurants. There is no tipping culture, so you do not need to pay extra service charges. Small gifts or expressions of gratitude are always welcome. Respecting local customs will allow you to have a more profound travel experience.

Korean food is popular worldwide. Beyond the basics like Kimchi, Bulgogi, and Bibimbap, there are many regional specialties. Be sure to try Dwaeji Gukbap (pork soup) in Busan and seafood dishes in Jeju. Street food is also a great pleasure of traveling in Korea. If you cannot handle spicy food well, you can ask for it to be less spicy before ordering. Experience the Korean dining culture, enjoying meals with a variety of side dishes.

South Korea has many attractions, requiring efficient planning. Seoul offers a blend of historical sites and modern shopping malls, while Busan is famous for its beaches and vibrant markets. Jeju Island boasts outstanding natural scenery, making domestic flight booking essential. Use the KTX to reduce travel time between major cities. By utilizing same-day domestic flight deals, you can get discounted Jeju tickets and visit multiple places even on a short trip. It is better to enjoy your trip at a relaxed pace rather than trying to fit too many things in.

Korea has four distinct seasons. Summer is very hot and humid, while winter is cold and dry. Spring and autumn are the best seasons for travel, but the temperature difference between day and night is significant. Pack clothes appropriate for the season; especially in summer, light clothing and an umbrella are needed, and in winter, thick coats and cold-weather gear are essential. The voltage used is 220V, and the outlet shape is similar to the European standard. Don't forget to bring a charging adapter and necessary medications.

To experience the real Korea, explore neighborhoods that are less frequented by tourists. Places like Ikseon-dong Hanok Village in Seoul or Gamcheon Culture Village in Busan offer a local atmosphere. Instead of large shopping malls, visit traditional markets to interact with vendors, and try a home-style set meal at a small local restaurant. Discovering the charms of smaller cities by utilizing low-cost domestic flights from Daegu is also a great option. Blending into the local life creates the most memorable travel experiences. TICKETS.CO.KR provides information on hidden photo spots in each city so travelers can capture the best moments. For example, seek out the night view from Inwangsan instead of Namsan Tower in Seoul, or find a hidden beach in Jeju.
