It was good there was a check-in counters and security check of first class only. But, it was not good there was no emigration of first class only.First class lounge was comfortable. Cabin attendant welcomed with smile. It was the seat surrounded by a pattition, such as modern living room with decoration of wood. The combination of the french courses and extensive wine selection ot top chef supervision were like a flying restaurant. After the turn-down service, I was able to sleep soundly dressed to the prepared pajamas. Cabin attendant gave me service in advance understand my needs. My heart was filled with the flight such as I stayed in Augerge. I was not tired at all in spite of the 12 hours of flight. British immigration was smooth in the use of fast track.I was able to spend without stress from the biginning to the end of the flight. I want to use JAL first class again.
