I am using vanilla reloads and BlueBird to pay my mortgage, car, and student loans. Just started doing that and it works out fine. I have been spreading the buys around, so as not to ring up a lot of this on one card. I was thinking that with these 3 payments alone I will put 35K on my credit cards. I put a lot on credit, but never that much! So maybe I should put 25K to 35K on one card and get a bonus. But what card and what bonus? I would like to get status on an airline. Or maybe do it on the BA card and get the companion ticket. Any suggestions?
