Is it possible for you to fly to Jeju directly?
Thanks for you response. I booked KIX-GMP with my United miles and I booked GMP-CJU with my Korean Air miles. I don't have enough miles to add GMP-CJU-GMP to my itinerary. Originally I was going to skip visiting CJU but then I remembered I had some Korean Air miles.
My itinerary is
LAX-ICN-NRT, KIX-GMP, GMP-CJU-GMP,
ICN-LAX.
The bold is booked with my United miles.
Hopefully, 2 hours is enough time to transfer to the domestic terminal.
