Was told the flight was overbooked so they selected only a few people to weight their bags and we were forced to check our luggage. We Once we got seated on the flight there were many seats vacant and our overhead bin was completely open. Both our luggage and our carryon were small. We had booked our tickets months in advance and we watched people carry two small suitcases on without one word to them. Am I upset?? Yes it was disappointing.

FAQs about flying to South Korea

South Korea climate

South Korea has four distinct seasons; spring and fall are ideal for visiting, while a rainy season begins in June and ends in a humid, sweltering summer in August. Winters are extremely cold.

Getting around South Korea

Buses specifically routed to many cities throughout Korea leave from directly outside of Incheon International Airport. Visitors can also choose to fly or take the train between cities; Korail is the major train company. Buses are an excellent way to get around and between each major city. Renting cars isn’t preferable, particularly in Seoul, as the traffic is intense and the driving habits of South Koreans aren’t always the safest or most predictable. Taxis are fairly convenient but can also be a bit pricey.

  • When is the best time to fly to South Korea?

    Spring and autumn are marvellous seasons to visit. The rainy season begins in June, and the rest of the summer is unbearably hot and humid. Siberian winds can make the winter numbingly cold, so unless you’re coming for the skiing or hot springs, it’s better to avoid the winters.

  • What is good to know if travelling to South Korea?

    Proper attention should be paid to being gracious and courteous in the Korean way. Koreans bow to show respect upon introduction, take their shoes off when entering the homes of others, and show extreme graciousness to the elderly. You should be prepared to do the same. And it’s probably best to avoid any political conversations or mention of past wars. Koreans have a strong sense of national pride and may take offense to anything they sense might be a slight encroachment on that, so err on the side of caution and stick to sunnier conversation topics. There are lots of other ins and outs regarding etiquette in Korea, so read up before you go.
