no promo for extra sign up bonus points/miles.
In fact, SW doesn't have very good promos (IMHO) for extra points at all.
Marriott is running a great promo right now for extra SW miles (if you stay at Marriotts).
I guess I should say, the credit card would be an exception that comment.
If you need a referral for a CC card I can give you one, but that's about it.
Once you sign up, go to your promo page (on the pull down menu) and you can see if they are offering any promos for youl
