Croatia Airlines will be adding new routes to its summer timetable, which begins this Sunday, marking the third consecutive year it has introduced new destinations to its network. The airline will launch seasonal two weekly flights from Zagreb to Dublin, and year-round operations to Mostar in May. Furthermore, it will boost frequencies on a number of routes. An additional weekly flight will be operated from the Croatian capital to Rome for a total of nine per week (via Dubrovnik or Split), while an extra frequency to St Petersburg and Tel Aviv will result in the two being maintained three times per week. Skopje will see the biggest increase out of Zagreb, with a further four return flights to be performed each week for a total of twelve. The Croatian carrier will also introduce a new seasonal service from Split to Copenhagen and from Dubrovnik to Munich.

On the other hand, Croatia Airlines will suspend four of its seasonal routes this summer. The airline will no longer operate two weekly flights from Zagreb to Pristina and from Dubrovnik to Nice. Furthermore, the carrier will cut its one weekly operation between Pula and Zurich and from Rijeka to London Heathrow. The Croatian airline will also discontinue five out of eight of its weekly flights from Zagreb to London Heathrow after selling its slots at the world's most congested airport. All other destinations will be served by the same number of frequencies as last summer season. Similar to last year, the carrier will add two wet-leased Iberia Regional Bombardier CRJ1000 aircraft to its fleet from May.

Please note that the changes listed below are preliminary and based on current availability in the Global Distribution System (GDS). Furthermore, the tables below display the peak weekly frequency on each route during the course of the summer season. Increases in frequencies, particularly on domestic flights between Zagreb, Dubrovnik, Split, Zadar and Pula, may not come into effect until later on in the summer and can vary depending on the time of the year.
