Air Lingus will launch two weekly flights from Dublin to Pula on Tuesdays and Saturdays in April.
Pula joins Dubrovnik as the carrier's second destination in Croatia, with return fares starting from €83.99 (approximately £69.74) per person including taxes and charges.
Also commencing in April, Ryanair will fly from Stansted to Osijek, in Eastern Croatia. Located on the River Drava, Osijek is the economic and cultural centre of the Slavonia region and flights take just over three and a half hours from the UK.
Return fares start from £61.98 per person.
