Sochi Airport's press service reported 26 delayed departures.
Five aircraft that had diverted to alternate airfields returned to Sochi after temporary operational restrictions were lifted, though the Samara-Sochi flight remains at its alternate airfield.
"Given the rolling delays, this number may increase. Airlines will need about two days to stabilize their schedules",
Sochi Airport press service reported.
A task force is currently operating at the airport, with customer service staff helping passengers resolve any issues that arise in the lounges.
