The Ink Bolds get a 7,500 point bonus for $25,000 spend, then another 15,000 point bonus for $50,000 spend, a total of 22,500 bonus points. If you max out the Ink Bold bonuses at the $50,000 limit, the Chase United Explorer gets a 10,000 point bonus for spending $25,000, nice if you were planning to transfer your UR points to United anyway.
