I have experience with this card. I've been an AU since we opened it in 2011. My niece and I share it. I don't remember her FICO at the time but it was prob high 600's low 700's. She moved to FL from IN, where we're from, and we started with $3k CL. I used it heavy in the beginning to fly there and for purchases, made payments for a few months, then PIF. She did the same thing. Between the 2 of us, we racked up a ton of points. The card sat at 0 balance for over a year, and I just did a CLI through the website, SP, and got bumped to $10k.
I've flown to spend time with her a couple of times now, for $10 RT from Chicago to FL. Best part is that a RT ticket on non peak times is often only 5000 points and $10. The only sucky part is the baggage fees, but for $10 RT, I don't care. LOL We still have prob 30-40k points left.
