LONDON, June 11 (Reuters) - London's High Court on Wednesday ruled in favour of aircraft leasing companies in a multi-billion-dollar legal dispute over jets retained in Russia since the 2022 invasion of Ukraine.

The world's largest aircraft lessor AerCap AER.N and several other firms had sued insurers including AIG AIG.N, Lloyd's, Chubb CB.BN and Swiss Re SRENH.S in one of the biggest insurance disputes ever heard in London.

The London lawsuit had focused on almost 150 jets and some engines, previously with a total value of up to $4.7 billion, though settlements – including on the first day of trial in October and subsequently – have whittled the numbers down.
