I haven't gotten this card yet (been working on Chase...3/5 so far), but they added BA and will add Iberia and Aer Lingus in the fall as transfer partners. Living in NYC, it'd be very easy to hit the 50,000 points on rent annually.

Also, 'Frequent Miler' says that you can now generate ACH info if you pay your rent through a portal..."In the Bilt Rewards app, cardholders have the option to send a rent payment by mailing a check or by ACH transfer using ClickPay, RentCafe, or other online payment portals."
