Have you heard about the city airport at midtown, where you can skip the queue at the airport and have your baggage check-in and departure immigration done?
I did not know about it until I was searching for the transportation to Gangnam, it was then I chanced upon this service that was shown at the official website. Having to know about this service make my return trip a swift and easy one, I was a little unsure and insecure because there is not much information about it.
Since i have the experience now, I hope to share this information here for more people to benefit from it. This post will be a step by step guide for travellers who wish to use the city airport terminal service at Samsung-dong City Airport Terminal (COEX).
