YMMV with other issuers, however, so make sure to ask what they do when a card is replaced for wear and tear.
Then just give your partner the card!
Hmmmm I wouldn't really advise this route it runs the risk of double losses/possibilties of theft. Best thing to do would be to call BA and let them know that you are now travelling seperately.
