airBaltic plans to wet lease out five of its aircraft over the winter period, a spokesperson for the company confirmed.
The airline operates a fleet of all A220-300s, totalling around 48 aircraft.
The ongoing GTF engine issues impacted the airline's second half 2024 results.
The airline's average aircraft on ground (AOG) in the first quarter of 2024 was three aircraft and six aircraft in the subsequent quarter.
"It is expected that the airline could face a shortage of engines from Q3 onwards due to shop visits caused by the powder metal defect," the airline read in its first half results. "The airline is still in negotiations with P&W regarding the commercial support levels for Q1 and Q2 of 2024."
In September, the airline had extended its wet lease partnership with Lufthansa Group.
The agreement outlined a three-year collaboration, with up to 21 deployed airBaltic A220-300 aircraft and the airline conducting flights on behalf of Lufthansa Group.
The airline's CEO Martin Gauss said: "The wet lease business has become a crucial element of the airBaltic growth strategy, complementing our scheduled operations from our existing bases.
"The efficient single-type fleet of modern Airbus A220-300s and our high-quality onboard service have been key to this success.
