Christophe Viatte, Chief Commercial Officer of airBaltic said the new route would provide a "convenient link for the business traveller between the capitals of Sweden and Latvia, and complements our excellent Riga-Stockholm Arlanda service."
The route will operate five times weekly using a Bombardier Q400 NextGen aircraft for a flight that will last 1 hour and 10 minutes.
One-way ticket prices will start at €35.
airBaltic serves over 60 destinations from its home base in Riga.
