Narrative:

We were cleared into position and hold on runway 25R waiting our flow time. After holding for approximately 1 min we were cleared for takeoff. During this time we noticed an air carrier airbus landing on runway 25L. This was an first officer takeoff and as we accelerated down the runway I noticed that the airbus had exited runway 25L at taxiway A6. We were at about 10-15 KTS below V1 when we saw the airbus continuing to cross our runway. We were about 4000 ft from that intersection and continued the takeoff. We rotated on speed and by the time we broke ground the aircraft was already clear of the runway. I would estimate that we were about 3500 ft from the other aircraft at the closest point during this event. I telephoned the las tower on our arrival at destination and spoke to a supervisor. It appears that the controller cleared the other aircraft to continue across our runway a little premature since we were not yet airborne. We agreed that making certain the takeoff aircraft is flying prior to clearing another to cross would prevent recurrence. Supplemental information from acn 511111: about 10 KTS prior to V1 (130 KTS) the airbus entered our runway 25R at taxiway A6 and was more than 1/2 way across as we rotated. Our rotation occurred between txwys A4 and A5 or approximately 3500 ft from the airbus. By the time we were abeam taxiway A6, the airbus was well clear of the runway. At no time did we deviate from our procedures or airspds.

Title: A B733 CREW DURING TKOF ROLL EXPERIENCED TFC CLRING ACROSS THEIR RWY AFTER LNDG ON THE PARALLEL AT LAS.

Narrative: WE WERE CLRED INTO POS AND HOLD ON RWY 25R WAITING OUR FLOW TIME. AFTER HOLDING FOR APPROX 1 MIN WE WERE CLRED FOR TKOF. DURING THIS TIME WE NOTICED AN ACR AIRBUS LNDG ON RWY 25L. THIS WAS AN FO TKOF AND AS WE ACCELERATED DOWN THE RWY I NOTICED THAT THE AIRBUS HAD EXITED RWY 25L AT TXWY A6. WE WERE AT ABOUT 10-15 KTS BELOW V1 WHEN WE SAW THE AIRBUS CONTINUING TO CROSS OUR RWY. WE WERE ABOUT 4000 FT FROM THAT INTXN AND CONTINUED THE TKOF. WE ROTATED ON SPD AND BY THE TIME WE BROKE GND THE ACFT WAS ALREADY CLR OF THE RWY. I WOULD ESTIMATE THAT WE WERE ABOUT 3500 FT FROM THE OTHER ACFT AT THE CLOSEST POINT DURING THIS EVENT. I TELEPHONED THE LAS TWR ON OUR ARR AT DEST AND SPOKE TO A SUPVR. IT APPEARS THAT THE CTLR CLRED THE OTHER ACFT TO CONTINUE ACROSS OUR RWY A LITTLE PREMATURE SINCE WE WERE NOT YET AIRBORNE. WE AGREED THAT MAKING CERTAIN THE TKOF ACFT IS FLYING PRIOR TO CLRING ANOTHER TO CROSS WOULD PREVENT RECURRENCE. SUPPLEMENTAL INFO FROM ACN 511111: ABOUT 10 KTS PRIOR TO V1 (130 KTS) THE AIRBUS ENTERED OUR RWY 25R AT TXWY A6 AND WAS MORE THAN 1/2 WAY ACROSS AS WE ROTATED. OUR ROTATION OCCURRED BTWN TXWYS A4 AND A5 OR APPROX 3500 FT FROM THE AIRBUS. BY THE TIME WE WERE ABEAM TXWY A6, THE AIRBUS WAS WELL CLR OF THE RWY. AT NO TIME DID WE DEVIATE FROM OUR PROCS OR AIRSPDS.
