By way of comparison:-
LA-Tokyo Narita with All Nippon two weeks ago.
At check-in, 1 hour before departure, my reservation was not found. (I had changed it but it got lost in the system). "Very sorry sir, but we will get you a seat!".
Arrived in Tokyo and I am met by ground staff at the gate. "Very sorry sir but your bags did not make the flight". I am escorted through immigration to the baggage claim desk and processed. Escorted through customs.
Missing bags are delivered to my home by courier the next day (about 3 hours after the next flight arrived in Tokyo).
Now that is service.
