Airlines price routes independently. Sometimes flying A → Seoul → B costs less than A → B direct. The difference is your savings — and Seoul is your free city.
Korean Air and Asiana anchor Seoul, but forty carriers compete for Incheon routes — the hub density is the fare gap. Gwangjang Market at midnight: mung bean pancakes from the stall with the queue, soju poured at the counter. Seoul runs 24 hours. The route saving bought your table.
