Croatia Airlines (OU, Zagreb Franjo Tuđman) has taken delivery of its first A220-100, following a direct non-stop ferry flight from Montréal Mirabel to Zagreb Franjo Tuđman on September 29-30, 2025.

9A-CAO (msn 50087) is the world's first unit of the type configured in the maximum certified density for up to 127 passengers.

The aircraft is powered by Pratt & Whitney PW1521G engines, is owned by Air Lease Corporation, and is the first of two units of the type that Croatia Airlines plans to add as part of its ongoing fleet renewal.

ch-aviation data indicates that the aircraft will enter service on October 10 and debut on the route between Zagreb and Munich. 9A-CAO will also operate to Dubrovnik and Hamburg on the same day.

"The aircraft will enter service after the completion of all necessary technical preparations and approvals from the relevant Croatian institutions," airline's spokesperson told ch-aviation.

The Croatian flag carrier currently operates six A220-300s, four A319-100s, two A320-200s, and four DHC-8-Q400s. It is set to receive seven more A220-300s and one -100 by 2027, becoming an all-A220 operator, as part of its fleet renewal drive. Croatia Airlines received its first A220-300 in July 2024.

Until now, the highest seat-count on in-service A220-100s was the single-class layout for up to 125 passengers installed by Swiss and ITA Airways.
