"Both routes will offer new travel options for travellers from the Baltics and Russia with convenient connections via Riga," the airline said in a press release.
Flights to Sochi will take place twice a week with tickets starting at €99. Flights to Kaliningrad are scheduled to take place six times a week and tickets start at €29.
“We are delighted to add Sochi and Kaliningrad to our route map next year, increasing the number of new destinations for next year to seven. Both routes will strengthen the business and tourism ties between Russia and Latvia, and will create convenient new connections with European and Scandinavian airports," said Wolfgang Reuss of airBaltic.
“Next summer both Sochi and Kaliningrad will be among the host cities for 2018 FIFA World Cup and the new connection via Riga will offer convenient flight options for those who are planning to attend the championship,” Reuss said.
airBaltic serves over 60 destinations from its home base in Riga, Latvia.
