Gets my thumbs up
I flew LHR-NRT return a couple of years ago with them in Economy. Pretty good all round. A 777 with a nice interior and reasonable IFE, uneventful ontime departure and arrival with no organisational troubles in evidence, reasonable food, good inflight service. It was altogether an impeccably organised and fairly pleasant experience. I utterly messed up the train journey to NRT and so missed the return flight; entirely my fault, and they quite reasonably (in my opinion) put me on the next day's flight for a GBP200 fare change fee (on a nominally nochange norefund max-discount ticket).
I'd fly them again.
