Narrative:

I dozed off in-flight. When I woke; I looked over and also saw that the first officer had dozed off. We were both asleep at the same time. The trip starts with an all-nighter departing at XA25. When I reported to work; I found out that our flight was delayed 1.5 hours. No one had called us to inform us of the delay. The flight attendants had all been notified and the inbound flight crew was notified at their hotel about 7 hours earlier. Today the same thing happened. We reported to work 1 hour before departure. The flight had been delayed 1.5 hours. We were not notified; but again the flight attendants were called 4 hours prior. After blocking in; we arrived at the hotel 30 mins later. That gave us only 9 hours and 40 mins at the hotel. We need to be notified of any and all delays of over 30 mins. That part is my opinion. If the first situation of not being called before an all-nighter happens to me again; I will call in fatigued! I was unsafe to fly the last hour and a half of my flight. The second situation; same solution; the crew desk needs to call us. If they are concerned of waking us; they can leave a message and we will get it when we wake. Or we can have all pilots call the crew desk before the start of every day.

Title: B757 FLT CREW BOTH FALL ASLEEP DURING ALL-NIGHT FLIGHT. THEY AWAKEN BEFORE ANY PROBLEM OCCURS.

Narrative: I DOZED OFF INFLT. WHEN I WOKE; I LOOKED OVER AND ALSO SAW THAT THE FO HAD DOZED OFF. WE WERE BOTH ASLEEP AT THE SAME TIME. THE TRIP STARTS WITH AN ALL-NIGHTER DEPARTING AT XA25. WHEN I RPTED TO WORK; I FOUND OUT THAT OUR FLT WAS DELAYED 1.5 HRS. NO ONE HAD CALLED US TO INFORM US OF THE DELAY. THE FLT ATTENDANTS HAD ALL BEEN NOTIFIED AND THE INBOUND FLT CREW WAS NOTIFIED AT THEIR HOTEL ABOUT 7 HRS EARLIER. TODAY THE SAME THING HAPPENED. WE RPTED TO WORK 1 HR BEFORE DEP. THE FLT HAD BEEN DELAYED 1.5 HRS. WE WERE NOT NOTIFIED; BUT AGAIN THE FLT ATTENDANTS WERE CALLED 4 HRS PRIOR. AFTER BLOCKING IN; WE ARRIVED AT THE HOTEL 30 MINS LATER. THAT GAVE US ONLY 9 HRS AND 40 MINS AT THE HOTEL. WE NEED TO BE NOTIFIED OF ANY AND ALL DELAYS OF OVER 30 MINS. THAT PART IS MY OPINION. IF THE FIRST SITUATION OF NOT BEING CALLED BEFORE AN ALL-NIGHTER HAPPENS TO ME AGAIN; I WILL CALL IN FATIGUED! I WAS UNSAFE TO FLY THE LAST HR AND A HALF OF MY FLT. THE SECOND SITUATION; SAME SOLUTION; THE CREW DESK NEEDS TO CALL US. IF THEY ARE CONCERNED OF WAKING US; THEY CAN LEAVE A MESSAGE AND WE WILL GET IT WHEN WE WAKE. OR WE CAN HAVE ALL PLTS CALL THE CREW DESK BEFORE THE START OF EVERY DAY.
