Find Cheap Flights to South Korea and Book Your Trip Now

Spring is the ideal time to see cherry blossoms and enjoy mild temperatures. It's the best time to find cheap flights to South Korea before the peak summer season, especially cheap flights to Seoul.

Summer brings heat, humidity, and the peak tourist season. If you seek flights from Portugal to South Korea now, book early, as flight prices tend to rise significantly.

Autumn is the most popular season due to perfect weather and stunning foliage. It is a great time to find cheap flights to South Korea from Lisbon, as prices drop after the summer peak.

Winter is cold and dry, but offers the chance to ski and visit palaces with fewer crowds. Look for South Korea flight promotions this season, as it is the low season for general tourism.

Portuguese citizens traveling to South Korea for tourism for less than 90 days generally do not need a visa, but they must obtain an electronic travel authorization, the K-ETA (Korea Electronic Travel Authorization), before flying. It is crucial to submit the application online in advance, ideally a few weeks before departure, as approval is not immediate. Your passport must be valid for at least six months after the intended date of entry. Always keep digital and physical copies of important documents with you. Although South Korea is a very safe country, having your documentation in order facilitates any interaction with authorities and the immigration process at Incheon Airport. Always check the latest rules on the South Korean embassy website before buying flights to South Korea.

The South Korean public transport system is efficient and modern, notably the KTX (Korea Train Express) for fast travel between major cities like Seoul and Busan. The subway in large cities, especially in Seoul, is clean, punctual, and easy to use, with signage in English. To pay, buy a T-money or Cashbee card, which works on buses, subways, and even taxis. Compared to Portugal, the system is more integrated and faster. For short distances, taxis are abundant and reasonably priced. Car rental is possible, but traffic can be intense and parking expensive. For domestic flights, consider low-cost carriers to travel to Jeju Island or Busan.

Accommodation options in South Korea range from luxury hotels to hanoks (traditional Korean houses) and jimjilbangs (public saunas where you can stay overnight). In Seoul, neighborhoods like Myeongdong and Gangnam offer convenience and easy access to the subway. If you are looking for a more cultural experience, consider staying in a hanok in Bukchon. It is essential to book in advance, especially if your trip coincides with high season or local holidays. When booking, check the proximity to subway stations, as this will save a lot of time. Remember that hotel rooms tend to be smaller than European standards. To find the best South Korea flight deals, combine your flight search with accommodation research.

Respect for hierarchy and elders is central to Korean culture. When interacting, use both hands when giving or receiving objects, especially money. Taking off shoes is mandatory before entering homes, temples, and some traditional restaurants. Avoid blowing your nose in public and speaking loudly on public transport. Tipping is not expected or common. Learning a few basic Korean phrases, such as "Annyeonghaseyo" (Hello), will be greatly appreciated by locals. Koreans are generally very helpful, but the language barrier may exist outside tourist areas. Remain calm and be patient.

Korean food is vibrant and often spicy. You must try Kimchi (fermented vegetables), Bulgogi (grilled marinated beef), and Bibimbap (rice mixed with vegetables, meat, and egg). Korean barbecue (Gogigui) is a mandatory social experience. In Portugal, meals are more individualized, but in Korea, many dishes are shared. Also, try Soju (a distilled rice alcoholic beverage) and street foods at night markets. In Seoul, Gwangjang Market is great for sampling local delicacies. Cuisine is an essential part of a cheap trip to South Korea.

South Korea is one of the safest countries in the world. Violent crime is rare. However, as in any large city, be aware of petty theft in very crowded areas, such as subway stations or markets. Tourist scams are minimal, but be wary of offers that are too good to be true. Healthcare is high quality but expensive; make sure you have adequate travel insurance before buying cheap South Korea air tickets. Wi-Fi connectivity is excellent throughout the country. For emergencies, the number is 119 (fire and ambulance) and 112 (police). Be aware of air pollution warnings during certain seasons.

For a first trip, focus on Seoul (5-7 days) to absorb modern and historical culture (Gyeongbokgung Palace, Namsan Tower). Then, use the KTX to go to Busan (2-3 days) to enjoy coastal life and temples like Beomeosa. If you have more time, cheap flights to Jeju Island are easy to find, offering unique natural landscapes. Try to avoid traveling during Chuseok (Harvest Festival) or Seollal (Lunar New Year), as transport gets crowded. For cheaper flights to South Korea from Lisbon, plan your trip outside these festive periods. Do not try to see everything at once.

Depending on the season, the climate can vary drastically. Summers are hot and humid, requiring light clothing; winters are very cold, requiring heavy coats and thermals. If traveling in spring or autumn, wear layers. A power adapter (Type C or F, the same as in Portugal) is necessary. Bring comfortable footwear, as you will walk a lot. A good power bank is essential, given the dependence on maps and apps. For a local experience, try visiting a traditional market early in the morning. For the best photo, go to Changdeokgung Palace at sunrise, when the light is softer and there are fewer tourists.
