Narrative:

It was the end of an 11 hour flight and 7 day trip as we approached the lax terminal area from the north. It was a clear 30 mi visibility day. We were assigned a heading 070 degrees after santa monica VOR and the captain asked the first officer to load runway 25L in the FMC even though we were to expect runway 24R. (It was in the hope we would be assigned 25 at the last min.) approach turned us heading 140 degrees and asked us if we had 1 O'clock traffic in sight for runway 24R. We said yes. Approach then cleared us for visual approach runway 24R to follow traffic and switch to tower. The first officer was switching radios and the captain was flying. I was the relief first officer watching for traffic. I noticed the captain wasn't turning final when I thought it was time. I then asked if we were still cleared for runway 24R or had I missed something and it was changed? The captain said we were still cleared runway 24R. I then asked if he had the airport in sight? He said yes. About that time the first officer told him also to go to runway 24R. By this time he was lining up with the 25's instead of runway 24R. We were telling him it was the wrong runway when we had a TCASII RA. It told us to climb which the captain did. At the same time lax tower discovered our error and said she had us and the runway 25 traffic in sight and for us to proceed to runway 24R. We landed without further incident. On debrief the captain said he knew we were cleared runway 24R but he had it in his mind runway 25 was runway 24. Also the FMC was never changed back from 25L to 24R. So he had information, even though false, to back him up.
