I have flown this route many times. Japan Airlines provides a consistent experience in both their hard product (seats, meals) and very helpful attitude of their employees. The seats in business class for this short flight (about 4 hours) are not lie flat and the window seats do not have direct aisle access. Typically these aren’t problems for a short flight. The boarding process was a stress free experience. On this particular flight there were high winds at Narita forcing multiple landing attempts. The pilot informed us of this possibility shortly after takeoff. It was useful to know this in advance.
