A Kremlin spokesman has told the BBC terrorism could not be ruled out as a possible cause of the crash.
At a news conference in Moscow, the deputy director of the airline, which was renamed as Metrojet, ruled out a technical fault and pilot error.
"The only explicable reason for the plane to have been destroyed in mid-air can be specific impact, purely mechanical, physical influence on the aircraft," Alexander Smirnov said.
Another airline official acknowledged that there had been previous damage to the plane's tail in 2001 during take-off.
But he said that the damage had been repaired, and was not thought to be a factor in the crash.
Saturday's disaster happened shortly after the Airbus 321 took off from the Egyptian resort of Sharm el-Sheikh.
