Best Time to Fly SEA (Seattle) to ICN (Seoul-Incheon)

The best time to fly from Seattle to Seoul often depends on a balance of weather and cost. Generally, shoulder seasons like spring (April-May) and fall (September-October) offer pleasant temperatures in Seoul and potentially lower airfares compared to peak summer months. September is often cited as a cheaper month for flights. Booking about 40 days in advance may also yield better prices. Consider major Korean holidays like Chuseok (Korean Thanksgiving, typically in September or October) when planning, as demand can be higher.
