Most of the 153 people killed in the Spanair crash in Madrid will have to be identified using DNA tests.
Spain’s Deputy Prime Minister Maria Teresa Fernandez de la Vega said 39 bodies had been identified through fingerprints, and 15 of the dead had been handed over to their families.
But she said the remainder will require DNA tests as they were badly burned.
Investigators are still scouring the wreckage of the MD-82 plane for clues.
Spanair reported an air intake valve was repaired just before the US-made plane crashed on take-off at Madrid-Barajas airport on Wednesday, but there was no immediate indication it was related to the accident.
Spanish newspapers highlighted financial problems and cost-cutting measures at Spain's second-largest carrier, which one paper said could have contributed to the accident.
On board the aircraft were 162 passengers, including two babies and 20 other children, plus 10 crew, four of whom were travelling as passengers.
The government said most of the passengers were Spanish, but there were citizens of 11 other countries represented on board, including five Germans and two French.
Spanish media said more than half the passengers were residents of the Canary Islands, where the flight was headed.
