How many hours before should I leave if I take a domestic flight?

I am planning to travel to Jeju Island this time.

Departure from Gimpo Airport.

I don't know because I haven't taken a domestic flight.

How many hours before should I leave for domestic flights?

Would it be better to set it for 2 hours like overseas?

An hour is enough

If you ride it hard, you can do it for 30 minutes
