Etihad Airways will next year begin daily services to Rome and Jaipur and a four-weekly service to Yerevan, Armenia.
The Gulf carrier will start flying to Jaipur on April 1, to Yerevan on July 2 and to Rome on July 15.
The new routes are in addition to those announced by the airline last week, including to Perth and Dallas (see news, December 13) and a previously announced direct service to Los Angeles (see news, October 8).
James Hogan, president and CEO of Etihad Airways, said: "This is part of a measured and strategic growth plan, which will reinforce the future of the national carrier of the UAE and the vital role it plays in the emergence of Abu Dhabi as a global aviation hub.
"Together with our codeshare and equity alliance partners, we have created a virtual network of more than 375 destinations."
To support the next phase of its global network expansion, Etihad will receive 20 aircraft deliveries next year, including the arrival of its first 787-9 Dreamliners and Airbus A380s.
The carrier will also receive five B777-200LRs, one B777-300ER, three A320s, three A321s and four A330-200s in 2014.
