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 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.

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

    Spring and autumn are marvelous 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 the best way to travel around South Korea?

    Proper attention should be paid to being gracious and courteous in the Korean way.

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.
