Serbia's flagship carrier is adding 10 Airbus A320neo to its fleet as part of expansion plans guided by its fast-growing partner Etihad Airways.
The Air Serbia deal announced on Tuesday at the Dubai Airshow is valued at more than $1 billion, but discounts are often given on multi-plane orders.
Air Serbia began operations in late October as the rebranded version of JAT Airways, the former state airline of Yugoslavia before the country's breakup in the 1990s. Abu Dhabi-based Etihad acquired 49 percent in JAT in August under a deal to manage the new airline for five years.
The Dubai Airshow has seen record orders earlier in the week for Airbus rival Boeing Co., including a deal for 150 of its planned 777X wide-body planes by Dubai-based Emirates.
