So now I have to see about a 50k offer and check the spend requirements and then consider if I want 50k more UR Points or should I go for the United card with a 50k signup and bonus 10k if I spend $25k. I can probably do the spend, but then I would be neglecting my Amex Plat and SPG cards.

I imagine that since they're both Chase and since I got the Sapphire Pref. card that I can only apply so many times for Chase cards within a month? Or can you, but it would hurt your credit?

Thanks!
