Swiss International Air Lines has outlined the planned schedule for its new Airbus A321neo aircraft, which it took delivery of last week. The carrier will utilise the jet, which has the capacity to seat over 220 passengers, on its flights between Zurich and Belgrade starting this month. Swiss has increased its frequencies between the two to twelve per week as demand for travel between the city pair continues to recover. Swiss’ competitor on the route, Air Serbia, has also upped frequencies to nineteen weekly, matching them to pre-pandemic levels. Swiss has a further seven A321neos on order.
