You don't mention interest rates, balances, or expected time to payoff...
I used a PenFed credit card to move some high interest student loans to a 4.99% for life no fee balance transfer. Must spend a small amount to join an affiliated organization to become a member. Chase Slate offers no fee 0% APR balance transfers for 12-15 months or so, considering moving some more student loans to that and saving a bit of interest in chunks here and there.
There may be others but those are what I'm aware of. If you cant' pay off in a few months others charge a fee, typically 3% to get 12+ months interest free, which is likely cheaper than waht you're paying now. Go ahead and optimize interest rate if you're serious about paying it off quickly and won't burn through the extra credit limit on those predictable monthly anomalies that push it off until next month indefinitely.
