I will be in Jeju on July 29 morning, and I need to go back to Vietnam on that very day. There is a flight with Korean Air than lands in Seoul Gimpo at 8.05am. I was considering to take it, and then fly again from Seoul Incheon with Vietnam airlines at 10.15am.
Given the 2 airlines companies are different, do you think 2h10 duration between the 2 flights will be enough?? Otherwise, there is another way to do it, but I would arrive much later in vietnam.
Thanks for your feedback!
