Airport Information & Terminals
ICN: Seoul airport system. Seoul international flights commonly use Incheon, while Gimpo handles many domestic and regional services. Airport rail works well; taxis are easier for late-night arrivals or heavy bags.
IAD: Washington DC airport. Washington DC airport transfer should be matched to the exact hotel, suburb or meeting area. Rail can work well for light luggage, but late arrivals, winter weather and family baggage often make a direct cab or booked transfer easier.
