Are direct Seoul to Houston flights available?

Best time or month to book

Either way, compare the nearby dates above before you settle on one.

Cheapest days for this route

What is today’s lowest airfare from Seoul to Houston?

The lowest fare we are currently showing is ₩797,047, on a Monday departure. Airfares change through the day, so search your dates for the exact price.

Should I book one-way or round-trip for Seoul to Houston?

United Airlines (33 flights, from ₩1,413,207), Korean Air Lines (21 flights, from ₩1,461,771), Delta Air Lines (17 flights, from ₩1,413,207), American Airlines (15 flights, from ₩797,047), Klm Royal Dutch (10 flights, from ₩1,828,576). Compare fare type, baggage and refundability — the cheapest airline is not always the best value for your dates.

Web check-in for your Seoul to Houston flight

Most airlines open web check-in 24–48 hours before departure on their own website or app using your PNR. Checking in early lets you pick better seats free of charge on many fares; FlyX also links every booking’s airline check-in page from Web Check-in.

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.

IAH: Houston airport. Houston 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.
