The Southwest Rapid Rewards Visa
now has an offer of 16 credits with signup ($59 annual fee). The signup bonus is enough for a free roundtrip ticket.

The Small Business version of the card also offers 16 credits as a signup bonus and a $59 annual fee.

I believe — though have not verified this myself — that the Southwest Visa can be churned (along with the British Airways Visa, Marriott Visa, and Priority Club Visa). Used to be that all Chase products could be signed up for multiple times, earning the signup bonus each time. That’s no longer the case with the United co-branded cards. But I don’t believe a lockdown on this has taken place with the other Chase products such as this one.

Anyone with recent experience, please share in the comments.
