ok thanks very much for your help...
looks like i will have to spend a night in tokyo then on the way to london
btw... does anybody know why there is the british airways flight from london to tokyo for about 55000 yen,, but then all other airlines like virgin atlantic, jal, singapore airlines, cathay pacific, emirates etc etc are all way over 200000 yen, sometimes up to 300000 yen???
cheers
