KKB, no you do NOT need to cancel his card that is linked to your account in order to open a new account in his name. I just did this recently, it is a totally separate account so will qualify for the 50,000 once the required amount is spent. Now I am thinking I will cancel my card so I will be able to get a new one in a few years!
I was really hoping that was the case. Hoping to repeat this the beginning of next year under his account! This a HUGE deal for us with a child at college 10 hours away...and another either heading there or further away!
I know my husband's cousin is an optometrist & they charge everything for the business on SWA cards so they actually earn companion status by spending $! Even if we charged EVERYTHING we buy we could never get there!
