Air Serbia will upgrade its core systems to the Sabre technology platform on April 22. The development will see Air Serbia move to a single, connected platform for passenger reservations, check-in and boarding, and all other critical airline operations including flight operations and network management. In addition, the airline will implement Sabre’s airport technology to enhance the service offered by Air Serbia Ground Services at Belgrade Nikola Tesla Airport. By migrating to Sabre’s software, Air Serbia will be able to streamline daily operations, reduce operating costs, strengthen revenue generation and retailing, and drive more ancillary revenue opportunities, enabling it to provide passengers with a more personalised service. Air Serbia's CEO, Dane Kondić, said last week, "It will make the whole system work much more efficiently and it will save us a lot of money in the longer term. It will enable us to do a lot more things that we haven't been able to do. Today, all airlines, whether they are full service, somewhere in the middle, or at the other end of the low cost spectrum, are all selling bags, and selling seats, monetizing certain things that we call ancillaries, that we can't do and that we haven't been able to do and I know people have been critical of us for not offering fares without bags for example. They are the things that are tangible, that people will be able to see". He noted, "There will also be far more seamless interlining between us and our partners and other airlines. It's not something people will see too much of but internally, for the company, it will be a massive step-change". Some of the airlines which utilise the Sabre system include Etihad Airways, Aeroflot, Alitalia, Aeromexico, Alaska Airlines, jetBlue, Volaris, Ethiopian Airlines and Vietnam Airlines, to name a few. In 2014, Air Serbia switched to the new SabreSonic Check-in system at Belgrade Airport, which was the first phase of the entire transition which will be completed later this month.
