Know what your public transportation options are BEFORE you book your flight.
There are way too many people asking about public transportation for flights landing 10PM or later. If you don't know how to navigate Korean public transportation, or know the bus or train timetables, or have private transportation, I HIGHLY suggest an earlier arriving flight.
I know, no one will pay attention to this post.
Even worse, some are arriving which young children at late hours with no firm knowledge of transportation, hotels or and plans or clue on where to stay or how to get to their next destination.Edited: 04 August 2018, 16:16
