Tbilisi International Airport will be closed to daytime flights for four months due to maintenance works on the runway.
Flights during the day will be cancelled or rescheduled for night hours instead.
The change will come into effect from March 1 and last for four months. The airport will return to normal operations in July.
A renewed flight schedule has not been released.
The airport administration told local media the airlines that normally flew during daytime hours at Tbilisi International Airport would decide whether to reschedule or cancel their flights.
Most international flights functioned in the early morning or late night at Tbilisi airport, while a handful operated during the day.
