At once it is necessary to say that there are no direct transfers from Kutaisi to Yerevan, therefore, if you arrive at Kutaisi airport, then directly from there you can buy a ticket to Tbilisi. The distance between the cities is 550 km. The road to Tbilisi is simple and takes exactly 5 hours, costs 20 GEL, and the bus arrives to the capital of Georgia at Liberty Square.

Then you can take a shuttle bus from Tbilisi to Yerevan. The journey costs about 20 USD, by a taxi 80 USD, or you can wait until the taxi driver dials more passengers, then the cost for each turns out about 25 USD, but remember, after 16:00 - 17:00 taxi drivers go home.
