Hey, From my experience flying both, the korean air vs asiana business class comparison comes down to comfort and service. Korean Air’s business class felt more spacious with sleek seats and a quieter cabin atmosphere. Asiana’s business class, however, had excellent food and a very attentive crew. While both offered top-notch service, Korean Air had a slight edge in overall luxury. If you’re choosing between Korean Air vs Asiana business class, I’d recommend Korean Air for longer routes.
