Thanks all

If I pick on the 9th, currently time slot I pick is jeju air with 12:25pm, then return on 13:05 12th nov
That should give me a full 36hour in jeju
I have no idea how huge my luggage will be yet, as the trip is 9-19/11
I booked Korean air Econ, given 23kg each, which I think a combined luggage weight for me n wife later won't be more than 20kg initially
Worst case scenario, we split two baggage, all bring to jeju as it gives 15kg each lol
Currently
Jeju air : 12:40 - 11:45 : 162000won
Air Busan : 14:45 - 13:05 : 146700won
Eastar jet : 13:05 - 12:50 : 126000won
Which 1 better?

Before I PM, what price do you guys expect, so that I know how much.
And how should I give the cash to you? Meet at Hongdae train station?
