Etihad Airways has seen the total number of destinations it serves increase to 269, either directly or with partner airlines.
The news follows a recent deal with airberlin.
The announcement means Etihad Airways now offers guests a route network more than 80 destinations larger than that offered by any other Gulf carrier.
As part of its deal with airberlin, Etihad Airways will sign codeshare agreements with the airberlin group for all European activities including NIKI, the Austrian airline and Belair, the Swiss airline.
Etihad Airways chief executive, James Hogan, said: “Today more than ever, it is vital to think differently in this industry.
“The number of codeshare partners Etihad Airways has, and the number of destinations it is now able to serve, is a point of marked differentiation.
“The Gulf is increasingly the centre of the world in terms of aviation, and we are happy that with one booking we are able, either directly or with codeshare partners, to allow our guests to take full advantage of this geography.
“We will continue to look to strike codeshare agreements with carriers around the world where we feel it is to the advantage of our guests,” Hogan concluded.
Etihad is considered the World’s Leading Airline by the World Travel Awards.
