Shame BMI status won't let you use the ANA lounges when travelling outisde *A.
I certainly would NOT advise travelling NH J if BA J was an option - can't tell you how
utterly disappointed I was with my recentish experience in ANA Business class - anyone who tells you that the keiseki menus in J are amazing is severely misguided - I know of several places in Tokyo and Yokohama that will give you vastly superior fare as part of a lunchtime set for about 2,000 or 2,500 yen (that's around a tenner) - and the seat wasn't that great either. Oh yes, my companions on that trip went for the western options on the menu and hardly touhed their meals - they
were pretty vile. (Both BMI and AC in Business had much better nosh). Still, I don't feel hard done by - the 2xmiles plus bonus on BMI's Diamond Club were extremely welcome!!!
Does travelling Virgin with *G allow you access to *A lounges? And is the Virgin lounge worse or better than these? (I've never seen this particular theme discussed even on the Japan forum)
