It sounds like you've been spending too much time on the drinking thread on AA.

JL does have several nice lounges, but they are all private lounges (like the Concorde room), and not J or F lounges ... thus JL will not have to allow any Oneworld trash into their good lounges. BA seems to have refused to move to the JL terminal at NRT (AA, CX and AY are moving there in Jan); probably because the lounge arrangement was unacceptable to BA.
