About Air Serbia
Air Serbia is the national airline of Serbia and the successor to the former Yugoslav carrier JAT, which is where its JU code comes from. It operates from Belgrade Nikola Tesla Airport. Most of its routes are within Europe and around the Mediterranean, with a particularly dense network across the Balkans, and it also flies a small number of long-haul routes to North America and China. Air Serbia is not a member of an alliance, but it has codeshare agreements with several larger airlines. Cabins are Business and Economy.
For Balkan routes, Air Serbia is often one of the few nonstop options, and you can check it on IATA.co. Search live fares in the booking portal or through the flights API, and pay from your prepaid balance. Air Serbia fares appear in your search results whenever our flight suppliers offer them for your route and dates. Fare rules are shown before you confirm.
Air Serbia airline codes explained
Air Serbia uses the two-letter IATA airline code JU and the three-letter ICAO code ASL. The IATA code JU is the one shown on tickets, fare displays and booking screens, while the ICAO code ASL is used in air traffic control and flight planning.
Air Serbia is a full-service carrier, based in Serbia, operating mainly from Belgrade (BEG). It is not part of a global airline alliance.
Booking Air Serbia fares as a travel agent
Travel agents book Air Serbia fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live JU fares in the booking portal: the price, baggage and fare rules are shown with each offer before you confirm, and the amount is deducted from your balance. Air Serbia results appear whenever our flight suppliers return them for your route and dates, so what you can book follows live supplier content rather than a direct airline deal.
Search Air Serbia (JU) through the flights API
Developers and agencies can run the same Air Serbia search from their own site, app or back office through the IATA.co flights API. Filter a search by the carrier code JU and read the fares back as JSON, then book from the same prepaid balance. See the flights API and the API docs for the full reference.
