We travelled with JAL again after our last two trips to Japan because they were so good. This time we were going through to London as an experiment to see if it minimised jetlag. It did, and we hit the ground running in London. The second and third legs of our trip,Tokyo to London and return to Tokyo were also very good. The best thing, apart from the service on JAL, is their Premium Economy seats. They are in a shell so that you never lean back into someone else's space and they don't lean their seats back into yours.
