America West FlightFund (Pre-2005 US Airways merger) - Lounge access in LAX

While HP fly from Terminal 1, they only list the NW lounge as a partner lounge in Terminal 2 (airside) as a partner lounge. Is this lounge accessable from Terminal 1 for HP flights?

If this merger goes through on thursday, there will be a HP lounge opening soon in LAX-T1. HP has been wanting the lounge for a year now. US just recently closed it.
