Are Korean carriers worth the extra cost?

Korean Air and Asiana typically offer better food, service, and seat pitch than US carriers for similar or lower prices. They're often the cheapest option anyway.

Should I book through the airline or third-party sites?

For Seoul flights, book direct with airlines. Third-party savings are minimal and you lose customer service access if issues arise during your long-haul flight.

What about error fares and flash sales?

Seoul error fares are rare but watch Scott's Cheap Flights (now Going) and Secret Flying. Korean Air occasionally has flash sales in February and September.

Is it cheaper to fly into other Asian cities first?

Not usually. Direct Seoul flights from the US are competitively priced. Adding Tokyo or Bangkok connections usually costs more in time and money.

How to Find Cheap Flights to Seoul from the US

Book Seoul flights 6-8 weeks ahead for best prices, typically $600-900 from major US cities. Use Tuesday-Thursday departures, consider Korean Air and Asiana for direct routes, and check both ICN and GMP airports. Peak summer and Korean holidays cost 30-50% more.

Start searching 8-10 weeks before travel. Flight prices to Seoul typically drop around 6-8 weeks before departure, but start monitoring earlier. Set up Google Flights alerts for your preferred dates and nearby airports.
Compare both Seoul airports. Incheon (ICN) gets most international flights but Gimpo (GMP) sometimes has cheaper options on Korean carriers. ICN is 45 minutes from Seoul, GMP is 25 minutes.
Check Korean carriers first. Korean Air and Asiana often have competitive prices and better service than US carriers. They also offer more direct routes from major US cities.
Use flexible date searches. Tuesday, Wednesday, and Thursday departures typically cost $100-200 less than weekend flights. Use Google Flights calendar view to spot cheaper dates.
Consider West Coast departures. Even if you're East Coast based, sometimes flying LAX or SFO to Seoul costs less than the connecting flight penalty from your home airport.
Book separate tickets carefully. Sometimes booking US domestic + transpacific separately saves money, but leave 3+ hours between flights and ensure both are on the same airline alliance for baggage.
