Civil Aviation Minister Sherif Fathy said it was a mark of respect to the victims and their families, BBC reported.
All 66 people on board Flight MS804 were killed when the plane crashed into the Mediterranean Sea on May 19th.
A deep-water search to locate the wreckage and the plane's "black boxes" will start in the coming days, France's BEA air safety agency said.
The Airbus A320 was flying overnight from Paris to Cairo when it vanished from Greek and Egyptian radar screens, apparently without having sent a distress call.
Among those on board MS804 were 30 Egyptians, 15 French citizens, two Iraqis, two Canadians and citizens from Algeria, Belgium, Britain, Chad, Portugal, Saudi Arabia and Sudan.
They included a boy and two babies as well as seven crew and three security staff.
Debris from the plane has been recovered from the sea, some 290km (180 miles) north of the Egyptian port city of Alexandria.
