Two ways to travel your last day in Seoul without a suitcase: send the bag ahead with T-Luggage (drop it at a subway branch in the morning, collect it at Incheon Airport T2 in the afternoon, from ₩20,000 on weekdays), or check in at Seoul Station before you ride the AREX Express — your bag goes straight onto the plane.
