As is typical with JAL it was a good comfortable flight. Leaving from San Diego, only one flight a day, is easy for us as we live in the area. Further it avoids the indignity, hassle, maltreatment and general nastiness of going through LAX. I regard LAX as to nations worst airport as regards service and the connection between domestic and international flights stinks.
Perhaps a bit too much food was served but other than that nothing to fuss about.
A nice feature is a washlet in the loo which I have not seen on other airlines.
