Narrative:

This was the last leg of a 7 day international trip with multiple time zone xings. The trip is as follows: lax-sfo-cdg-ord- cdg-lax. It is extremely grueling. We were approaching lax from the north, over smo VOR. Approaching smo we were assigned runway 24R. We requested runway 25L to reduce taxi time after landing, but our request was denied. The captain was hand flying the airplane. He acknowledged that our request for runway 25L had been denied. On base, approach control asked if we had the airport in sight, which we did. He cleared us for the visual to runway 24R. He then asked us if we had the traffic in sight for wry 25L, which we did not, as we told approach. On base, it became apparent that we were going to overshoot, but I thought the captain was just failing to compensate for the northerly crosswind. Apparently, though, he had it in his mind that we were cleared to runway 25L. As we lined up on runway 25L we got TCASII warnings and a call from the tower, who said she had us both in sight. We corrected back to runway 24R and landed uneventfully. I believe we were all 3 slow to react because of extreme fatigue.

Narrative: THIS WAS THE LAST LEG OF A 7 DAY INTL TRIP WITH MULTIPLE TIME ZONE XINGS. THE TRIP IS AS FOLLOWS: LAX-SFO-CDG-ORD- CDG-LAX. IT IS EXTREMELY GRUELING. WE WERE APCHING LAX FROM THE N, OVER SMO VOR. APCHING SMO WE WERE ASSIGNED RWY 24R. WE REQUESTED RWY 25L TO REDUCE TAXI TIME AFTER LNDG, BUT OUR REQUEST WAS DENIED. THE CAPT WAS HAND FLYING THE AIRPLANE. HE ACKNOWLEDGED THAT OUR REQUEST FOR RWY 25L HAD BEEN DENIED. ON BASE, APCH CTL ASKED IF WE HAD THE ARPT IN SIGHT, WHICH WE DID. HE CLRED US FOR THE VISUAL TO RWY 24R. HE THEN ASKED US IF WE HAD THE TFC IN SIGHT FOR WRY 25L, WHICH WE DID NOT, AS WE TOLD APCH. ON BASE, IT BECAME APPARENT THAT WE WERE GOING TO OVERSHOOT, BUT I THOUGHT THE CAPT WAS JUST FAILING TO COMPENSATE FOR THE NORTHERLY XWIND. APPARENTLY, THOUGH, HE HAD IT IN HIS MIND THAT WE WERE CLRED TO RWY 25L. AS WE LINED UP ON RWY 25L WE GOT TCASII WARNINGS AND A CALL FROM THE TWR, WHO SAID SHE HAD US BOTH IN SIGHT. WE CORRECTED BACK TO RWY 24R AND LANDED UNEVENTFULLY. I BELIEVE WE WERE ALL 3 SLOW TO REACT BECAUSE OF EXTREME FATIGUE.
