Jat Airways was the national flag carrier and the largest airline of Serbia. Jat Airways was rebranded as Air Serbia in October 2013.
The Jat Airways logo was probably created using FF Scala Sans Regular with a few minor lettering changes. It comes in 10 weights, from Light to Black in Condensed and Normal, and was created by Dutch type designer Martin Majoor exclusively for FontFont (including italics).
