How many minutes before should I go and check-in for domestic flights?

We're going to Jeju Island this time.

I don't think I need to go check in a few hours in advance as much as abroad.

How long ago should I go and check in?

Usually, 30 minutes before is enough.
According to the airline's indication, if you come after 30 minutes, you can't get an assignment even if you have a reserved seat.
