Alaska Airlines, Korean Air and Hawaiian have round-trip flights from Houston (IAH) to Seoul (ICN) for $850-$853 with a connection. Flights in April, August, September, November, and January. No Thursday departures. 7-day minimum stay required. No Thanksgiving dates.
Some small OTAs on Skyscanner have this for as low as $843; which is cheaper than the airline. If you plan on booking there, beware of any site that charges a fee to cancel a ticket within the 24-hour “free” period. Use unknown booking sites at your own risk.
