All 45 people on board perished when a Pakistan International Airlines Fokker aircraft crashed soon after take-off from the city of Multan and burst into flames.
It is not clear what caused the crash, but eyewitness reports suggest it may have been a technical fault. Bodies of the dead were charred beyond recognition.
Technical malfunction is one line of inquiry crash investigators are pursuing. Witnesses say they saw flames coming from the plane after take-off. Others say it hit a power line.
Some politicians recently argued that the planes should be grounded as they had flown more than the recommended hours, but officials said they were fit to fly.
Rescue workers from the privately run relief foundation Edhi, the Civil Aviation Authority and troops helped recover bodies and sift wreckage for clues to the cause of the crash.
Fires raged for about an hour, beating back residents and rescue workers.
