It is my 2nd time flying to Seoul in Korean Air. Majority of the passengers on the flight are Koreans and airline crew automatically speaks to you in Korean which I can't understand. They will only speak in English when you start to answer them back in English. Food is good for Korean selection. The crew are also friendly and well groomed. The only minus point is flying out of Seoul on Korean Air is the 23kg baggage allowance. How is it possible not to overshop in Seoul? Airline starts charging for excess baggage at 23kg. I always ended up paying for excess baggage.
