Have a Finnair Super light trip departing on an AY codeshare operated by BA. Unfortunately BA app says ‘no checked baggage’ and having spoken to them they couldn’t help and advised Finnair. The Finnair rep on chat just said ‘they will know at the airport’ checked baggage is free if you point out status. I’m not sure as this will be a UK regional airport… Any recent experiences from codeshares from non AY airports? Thanks
