I had written earlier about a 20K signup bonus Ultimate Rewards (UR) points for the Chase Freedom card. Recently they have been sending out a targeted offer for 30K UR points. If you have applied for the card in the last 3 months, it might be worthwhile asking them to bump the bonus on the card to 30K. The promo offer code is D1R.
Ultimate Rewards points are transferrable to Continental (CO), British Airways (BA), and Hyatt at 1:1 if you have Chase Sapphire Preferred. Otherwise, these points are worth ~1 cent.
