Croatia Airlines has disclosed that it invested in increasing the maximum authorised weight of two Airbus A220 aircraft during the first half of the year. The carrier did not identify the aircraft or specify which variant was involved. A higher certified weight enables the aircraft to carry more fuel or payload, providing additional range and reducing potential restrictions when operating with a full passenger and baggage load or in adverse weather conditions. It does not increase seating capacity but provides greater operational flexibility, particularly on longer routes. The work was included within a broader 1.1-million-euro investment item covering modifications to leased aircraft, which also encompassed work on an Airbus A320 engine. Croatia Airlines did not disclose the individual cost of the A220 upgrades or the aircraft’s revised weight limits.
