Your bags with KE should be tagged and checked thru to CDG at KIX, Boarding Passes issued for both flight segments - similar to our TPE-ICN-JFK routing earlier this month (confirm that with the ticket stubs given to you at the counter)

Flight will arrive ICN's gate into level 2 (floor) - follow signs for Transit Passengers (keep right) - go thru security by showing your BP(no bottled water, 3-1-1 and laptop/tablets out on its own tray for screening, belts off, shoes on) and then escalators/elevators one level up to 3/F for departure flight, check the display monitors for your gate.

There is no need to see the gate agent at the counter, boarding time as indicated (announcement is done in Korean first, so it's a disadvantage to English speakers) with First/Business class & elite status flyers invited to board first (along with those traveling with infants/small child or special needs)
