There was some talk a week or two back about Business cards being harder to get, especially second+ cards, and perhaps the world ending. I just got approved for my third in the last year (and a day), with both of the others still open. CL = $7000, the highest business CL I have gotten in a long time, if ever. My wife also got approved, although it has been a year (and a day) since her last one and she had none open.
Both of our applications were deferred and hers approved a couple of days later without calling while mine took three calls, the first to someone I could barely understand, the second to someone relatively unhelpful, and after a week since application the third was great and got me approved.
