Chase has rolled out PYB to the Southwest cards - not a good redemption option, unfortunately.

For this rollout there are 2 categories, AF and Dining. Both are worse CPP than using the points for flights. AF is 1 cpp and dining charges are 0.8 cpp. I'd only look at it if you were trying to leave the ecosystem and were going to abandon points in the process (they don't expire so you could always change your mind.) Or possibly offsetting the AF, that's not too terrible value wise, if points are an easier spend than cash for you.
But with Aeroplan and now Southwest, seems like there may be a plan to roll out to more co-brands. Keep an eye out for something more interesting!
