Flights to Jeju Island (Jeju-do)

Flying to Jeju Island from the mainland of South Korea is easy. It's less than an hour in the air from Busan, and even by boat from Incheon, all the way up near the border between South and North Korea, I believe it is only about 10 hours in the water. After arriving in Jeju-si from the airport, I admired the coastline for about 15 minutes and saw at least three planes arriving. Jeju-do is a popular vacation spot for Koreans and, less so, foreign tourists.
