Moscow imposed a transportation and postal blockade on Georgia in October 2006, apparently in retaliation for the detention on espionage charges of four Russian army officers.
Russian officials cited commercial reasons, however, saying that Georgian airlines owed Moscow more than $3 million for air traffic services. Tbilisi claimed that the move was politically motivated.
"We are ready to resume air links on March 30, after Georgia pays a debt of $2 million March 10, to the State Air Traffic Management [ATM] Corporation," the source said.
The source added that the agreement on the debt repayment was reached during a two-day visit to Moscow Monday by a Georgian governmental delegation for talks on resuming flights.
Earlier in the month Georgian President Mikheil Saakashvili ordered a special department on Russian affairs be set up within the country's Foreign Ministry.
The president said the department had to improve relations with Russia, marred in particular over Russia's alleged support for the breakaway republics of Abkhazia and South Ossetia.
