I applied for a sw credit card a few years ago and got the bonus points.

Im thinking of having my wife apply for a sw credit card to get the 75k bonus points (and a couple other minor perks). I think shes eligible for the bonus points because the original one is under my name. I did get an authorized card for her to use. Is she eligible for the 75k bonus points?can she tie that to the current sw account we are currently using to spend points?
