Thanks for the info.

I'm wondering what paragraph 22 says - however, in reality, the flight route to JFK is via NRT, howcome LAX comes up in paragraph 22?

By the way, I asked my initial questions to an agent, and the agents says (very briefly), that this ticket can be endorsed to JAL without surcharge provide the same routing, and endorsable to a US carrier with a surcharge; also endorsable and rerouteable over Europe, but subject to a surcharge. The thing is, when I ask what the surcharge means/is, I am not getting any answer.
