Actually, no -- the promo is offered by Southwest, not Chase. So it would be best to contact Southwest (I recommend via Twitter). That's a great question. I too have both personal and business cards, and have the same experience. I registered for the promo for one card, and when I click thru the "register now" link for the other card it tells me I'm already registered. This should mean that, at a minimum, the offer applies to both accounts. Hopefully it means that purchases from both cards will be combined when calculating totals for threshold and bonus. That does seem to be the case with the previous version of this promo -- but of course nothing I say is official, just my experience. If you do get a response from Southwest, please come back and give us an update!
