When I went there, I didnt feel very crowded. I will be there soon, and the customs clearance is very smooth. However, when you return to the city, you will faint, because you have to refund the tax, so first queue up to go to the tax rebate, and then go to get the ticket and line up, people are too many, I feel that at least 3 hours in advance may not have time. Feeling surrounded by purchasing, huh, huh. The security check is still ok. After entering, the tax refund is arranged on the opposite side of the 16th door, and the payment is directly paid to the account. The convenience is convenient. Then go to the duty-free shop, in fact, is to bring cosmetics to friends, the mask is very cheap, dead, almost overweight, the next time is not happy to bring. There are not many places to visit, plus dinner is full, so there is nothing to go shopping, while the tax-free extradition field is shocking, blue plastic bags are flying all over, people can buy cosmetics can use sacks Come and install, everyone is fascinated and interesting. There are snacks in the queue, and the airport is still too small. However, the introduction is the third largest airport in Korea, second only to Gimpo and Incheon in Seoul.
