True to form with Korea’s public transportation network, you can take a “limousine bus” directly to the airport from any midsize city in Korea, even in the far south. (For the uninitiated, a “limousine bus” has limited seating in comfy chairs almost as good as airplane seats.)
Airport busses mean no tolls, no parking fees, and no rental cars. They also mean you don’t have to ask someone to wake up in the wee hours of the morning to take you to the airport. No fear about making connections with your pick up person; there’s a bus running every half hour. Even better, after getting up at “dark-thirty” to catch that morning flight, instead of guzzling coffee and slapping your cheeks, you can simply lean your chair back and reclaim some of those lost Z’s as your bus driver safely delivers you to the airport. Nicely done, Korea!
