Excellent news and well done persevering with this one. In order to minimise the risk of receiving a compensation denied letter when submitting your partners claim, make sure you cross refer your own successful case reference to speed things up on BA's side when applying for hers. In my somewhat limited experience in this situation, BA don't seem to keep a database of eligible flight numbers/dates to pay out on and instead try it on by not paying up as a standard practice.
