Note that it is not permitted for British citizens to enter Sweden from Denmark, so don't make the mistake of flying to CPH and expecting to take the train to Sweden or flying MAD-CPH-ARN or something. MAD-FRA-ARN probably works, but double-check before booking anything. Once at ARN, you can either take a train or a domestic flight to other parts of Sweden.
