The only reason for giving four stars instead of five was that the plane felt ready for a refresh. The wear and tear on the seats and seating areas were apparent. So that said, I can't recommend the airline highly enough when it comes to service and quality. The air hosts were all absolutely amazingly attentive. Their dedication to ensuring that passengers had a comfortable flight was apparent from the moment we boarded until our departure and this was true on both our inbound and outgoing flight. A pal who travelled first class said it was superior in all respects. The food was light years better than the food I've experienced on other airlines, the bed was comfortable, the beverage selection was first rate and the flight was smooth and utterly painless. I arrived in Japan refreshed and ready to explore. I would absolutely recommend this airline and I would fly with them again in a heartbeat.
