Narrative:

On landing at las, failed to acknowledge tower's direction to 'hold short of runway 25R' after we had landed on runway 25L. While this resulted in no problems, it is symptomatic of the fatigue I was experiencing as a result of a long duty day, (4 different destinations) in the middle of the night. I was ok on the second to third leg, but leaving on my third leg, I did not realize how tired I really was. Even though an 11 hour 17 min crew duty day and 7 hour 53 mins of scheduled flying time is legal, it does not mean it is safe when flown in the middle of the night. The corrective action is not to schedule trips like this. But that failing, I should have gone into crew rest at the third airport. Maybe I was too tired to know I was too tired. Supplemental information from acn 537465: the corrective action should have been to go into crew rest at our third destination airport. Even though an 11 hour 17 min duty day and a 7 hour 53 min flight time in the middle of the night is legal, doesn't mean it's safe! This pairing is an accident waiting to happen.

Title: A B757-200 CREW, AFTER LNDG AT LAS, CROSSED THE PARALLEL RWY THEY WERE TOLD TO HOLD SHORT OF.

Narrative: ON LNDG AT LAS, FAILED TO ACKNOWLEDGE TWR'S DIRECTION TO 'HOLD SHORT OF RWY 25R' AFTER WE HAD LANDED ON RWY 25L. WHILE THIS RESULTED IN NO PROBS, IT IS SYMPTOMATIC OF THE FATIGUE I WAS EXPERIENCING AS A RESULT OF A LONG DUTY DAY, (4 DIFFERENT DESTS) IN THE MIDDLE OF THE NIGHT. I WAS OK ON THE SECOND TO THIRD LEG, BUT LEAVING ON MY THIRD LEG, I DID NOT REALIZE HOW TIRED I REALLY WAS. EVEN THOUGH AN 11 HR 17 MIN CREW DUTY DAY AND 7 HR 53 MINS OF SCHEDULED FLYING TIME IS LEGAL, IT DOES NOT MEAN IT IS SAFE WHEN FLOWN IN THE MIDDLE OF THE NIGHT. THE CORRECTIVE ACTION IS NOT TO SCHEDULE TRIPS LIKE THIS. BUT THAT FAILING, I SHOULD HAVE GONE INTO CREW REST AT THE THIRD ARPT. MAYBE I WAS TOO TIRED TO KNOW I WAS TOO TIRED. SUPPLEMENTAL INFO FROM ACN 537465: THE CORRECTIVE ACTION SHOULD HAVE BEEN TO GO INTO CREW REST AT OUR THIRD DEST ARPT. EVEN THOUGH AN 11 HR 17 MIN DUTY DAY AND A 7 HR 53 MIN FLT TIME IN THE MIDDLE OF THE NIGHT IS LEGAL, DOESN'T MEAN IT'S SAFE! THIS PAIRING IS AN ACCIDENT WAITING TO HAPPEN.
