I have roughly between $5k to $8k in credit card debt each month - but that's always paid off before it's due.
About 75% of my credit card debt is company expenses (airfare, hotels, business lunches/dinners, etc...). Aside from that, I put everything I can from my personal expenses on Visa and pay it off as soon as I get home, because I have a General Motors Visa that gives me 3% towards my next vehicle. I never pay interest because I pay my debt off before it's due, and ended up with the maximum allowed $5,000 off of the vehicle I purchased last year.
Because I use my Visa so much for business, it maxes out the GM points I'm allowed to accumulate rather quickly. So, once I max out my GM Visa points, I start using my Aeroplan (Air Canada travel points) Visa so I start earning travel credits. Took the family to Disneyland last year pretty much for free.
