Efforts to resume direct air links between Georgia and Russia have been hit by turbulence.
Moscow has given a Georgian airline permission to fly to Russia for the first time since the two countries fought a brief war last year.
But Georgian Airways says authorisation has come too late to organise the charter flights this Tuesday and Wednesday. As a result, flights will not take place until January 6th at the earliest.
There is no agreement yet on the resumption of regular flights between Russia and Georgia.
But, in a sign of thawing ties, Moscow last week announced the opening of a key border post between the countries for the first time since the war.
