Can I safely take my 6 year old son on a flight to Jersey if he doesn't have a valid passport? I'll have mine & he can bring his old one (expired last year but baby photo that looks nothing like him!) plus his birth certificate and we have the same surname. We can't renew it in time to travel & the only advice on BA's website say not essential but recommended to take photo ID and obviosuly he doesn't have any other photo ID!
Do I risk it?
