Vanilla Airlines is promoting their new route between Tokyo Narita NRT and Hong Kong HKG with fares as low as 8,000 JPY each way (before taxes and fees.)
Most of the 8,000 yen fares are gone, but I do still see a bunch of dates available at 9,000 yen. Keep in mind the fare type, Simple should be good for most people as it includes baggage allowance still.
With the yen the weakest in years, this is a great time to capitalize on travel to Japan.
At the moment they only fly Sunday, Tuesday, and Thursday between Tokyo and Hong Kong, but come February 2015 it’ll switch to daily service.
