Depends on what you're looking for.
I've tried both terminal express bus and metro (no worries for traffic)
and both are pretty convenient.
Both can get you to Seoul within 90-120 minutes and east to get tickets from airport. about 5 years agoAnswered by Paul Kim via WorldNomads.com
If you have only a small luggage it's ok to take the airport limo bus, you can get the tickets inside the airport. But if you have more than 1 and heavy luggages, you should take the taxi, there are taxis with certified english speaking drivers. about 5 years ago
If you have a lot of luggage I'd suggest taking the airport bus. If you have little luggage the cheapest and best option is to take the subway (Arex) which can be direct to Gimpo and Seoul Station or express train which stops at numerous stops along the way.
