If you search Expedia for a round-trip flight from Osaka to Naha, the cheapest is $895. If you search JAL’s site, $335. In other words, while it’s fine to use sites like Expedia for your international flights, they’re (coughcough) “suboptimal” for domestic.

And, before you ask, the purpose of this tentative side trip is not to search for busty alien catgirls, but if any show up, I’ll be sure to get pictures.
