Anybody has and experience in stand-by (looks like they don't use the word stand-by, instead it's called
空席待ち in Japanese FYI) at Tokyo Narita with
Japan Airlines (JAL)?
I've tried to look up online about how they handle stand-by for international flights at Narita, but no info came up so far.
This one explains (in Japanese) how another company in Japan (Skymark) handles that, but not JAL.
By the way, with the other major airline company in Japan,
ANA, I don't find any sound info online either.
