Etihad Airways will launch services to Baku, Tbilisi and Dar es Salaam in winter 2015.
The Gulf carrier will operate a four-times weekly service to Baku, the capital of Azerbaijan, from October 1, while a three-times weekly service to Tbilisi, the capital of Georgia, will begin on October 2.
The airline will start a daily service to Dar es Salaam in Tanzania on December 1. It will be Etihad's fourth destination in east Africa.
Flights to all three destinations will be operated using A320 aircraft in a two-class configuration, with 16 seats in business class and 120 in economy.
James Hogan, Etihad's president and CEO, said: "The development of Etihad Airways' network will be accelerated in 2015, supporting a long-term vision to position Abu Dhabi as a leading international travel hub, with extensive connections across the globe.
"We have announced nine new destinations so far for next year, including Baku, Tbilisi and Dar es Salaam, and we look forward to aligning operations and enhancing codeshare agreements with our strategic airline partners on these upcoming routes."
Etihad is set to next year fly its new A380 to Sydney (see news, August 28) and will also launch its first service to Scotland with a non-stop daily flight between Abu Dhabi and Edinburgh (see news, July 10).
