It said all other sectors have suffered losses due to movement restrictions and lockdowns aimed at limiting the spread of the novel coronavirus.
Air Algerie suspended both external and domestic operations in March before operating some emergency flights mainly from Europe, Turkey and Gulf countries.
That suspension caused losses estimated at 16.31 billion dinars by April, a figure that may climb to 35 billion by the end of the year, Finance Minister Ayman Benabderrahmane told a meeting with businessmen and unions.
President Abdelmadjid Tebboune has said air, sea and land borders would remain closed until the end of the health crisis.
The meeting, chaired by Prime Minister Abdelaziz Djerad, was intended to set up a commission with the aim of evaluating overall economic losses from restrictions linked to the virus.
"The state has taken preventive measures to cope with the health crisis. These measures have seriously affected the national economy," Djerad told the meeting.
He cited energy, construction, public works and transport as the main sectors that have suffered since the government started imposing restrictions in mid-March.
OPEC member and gas-exporting Algeria has already announced public spending cuts and delayed planned investment projects for this year in sectors including energy to ease the impact of lower oil prices.
"Algeria is facing an unprecedented economic situation," Djerad said.
