I've already hit EXP for next year so figured i'd take a non oneworld flight direct from LAX to ICN return. This is for business so within reason we can book pretty much any business class flight. That said which airline + aircraft do you recommend ?
I see Singapore Airlines, Asiana and Korean Air have direct flights from LAX , i could also depart from SFO.

Never flown any of the above so looking for recommendations. Also, anyone stayed at the JW Marriott in Seoul? Any other hotel recommendations that are central?

Thanks
