A London High Court ruling has mandated major insurers to pay $4.5 billion in claims to aircraft lessors for 147 planes and 16 engines stranded in Russia since the 2022 invasion of Ukraine. The court found that war-risk insurance policies cover these losses, marking what could be the largest aviation insurance payout to date. Among the claimants, Dublin-headquartered AerCap secured an award of approximately $1 billion (€870 million) from the UK court for its aircraft and engines seized in Russia. This ruling is expected to provide a precedent and support for companies seeking compensation for assets stranded in conflict zones with little chance of recovery.
