With the (non-)Amex corporate cards we have, as well as the central account address which is the company address, it is possible to specify the mailing address for each cardholder's statement. If Amex offers the same on its corporate cards, then perhaps darrenkell could see if his company can change the address for his own card statement his home address (without changing the company's main address).

This might also be why Raffles got points from an Amex Corporate card and darrenkell did not.

To answer PanGalactic, if the HHA is dissolved any children's accounts may be closed and status therefore lost as BA only lets children have accounts as part of a HHA (I don't know why this is the case - other airlines don't all have this restriction, only that a parent/guardian has to be responsible for the account). But if darrenkell's BAEC address does need to be changed to his work address for him to benefit from the Amex Corporate points, it may be possible for him to nominate a new adult head for the HHA resident at his home address and therefore keep the kids' accounts open (maybe this is a question for Nicci?)
