"I can inform you that we have identified 50 of the bodies through Tuesday midday," Forensics Office Director Sergio Rabell told a news conference.
The Mexicans identified include the pilot, Angel Luis Nuez Santos, 53, and the co-pilot, Miguel Angel Arreola Ramirez, 40.
Still awaiting identification are the remains of a couple from Argentina, a Mexican tourist, a passenger from Western Sahara, and some 50 Cubans, Rabell added.
The Cuban government is investigating the cause of the crash and some of those killed have already been buried.
Transport Minister Adel Yzquierdo has said one of the plane's two black boxes had been recovered in "good condition," and the other was likely to be found. Their data will be key to determining what happened.
The 39-year-old plane, leased from a Mexican company, Global Air, was on a domestic flight to the eastern city of Holguin, where most of the passengers were from.
In Mexico, Global Air's operations were suspended so that Mexican aviation authorities can run inspections of the aircraft it leases following the tragedy in Cuba.
The review will again inspect aircraft already certified as safe to fly, and assist as needed in the investigation of the accident in Cuba, a company statement said.
Built in 1979, according to the Mexican government, the Boeing 737 that crashed last passed inspection in November 2017.
The accident happened Friday at 12:08pm (1608 GMT). The plane crashed in a potato field close to Havana's airport. Witnesses and airport officials told AFP that the aircraft plunged as it was making its first turn after take-off.
Most of the plane was reduced to a mangled carcass of burned metal. It came down just 200 meters from houses between the Boyeros and Santiago de Las Vegas districts south of Havana.
