about china travel.

the 100000 yen rate is on ANA and JAL flights right?

as a dirty thing, japanese airlines only offer cheap prices to japanese passport holders.

but try out Air china or china southern, there you get a ticket starting cheapest at 39000 yen. if you want for example beijing in and shanghai out , you pay 60000 yen on airchina,
and you can get miles if your are lufthansa m and m
