As I expected would come, a new CP offer for new cardholders who have not taken a sign-up bonus in the past 24 months.

The email I got came from Southwest (not Chase).

Must-sign up in the next month through the link (not provided here), and then 90 days to do the $5k spend, then you get the CP turned on with an expiration of 2/28/23 (so for most people, less than 1 year) plus the 30k points. Unfortunately, I still don't see a lot of leisure (or business) travel so bringing someone along is not a high-value yet.
