Ok, someone in here said that all N. America to Seoul flights are always full. This is possible, but I have to raise this question. Asiana operates the SEA-SEL flight, non-stop, but not on a daliy basis. Why isn't this flight upgraded to a daily? Lack of aircraft? This person said that he/she could not even find a flight from ANY N. American port to Seoul for his/her trip. Also, does Asiana use combi aircraft for this flight? Thanks in advance!
