Credit card offers & mileage runs

You'd be wise to use the search function and do a lot of reading. No one knows your situation better than you do. Do you really think people can advise you on what to do with that little piece of information?

If you're thinking that you can get a bunch of miles to get a cheap vacation, I think that is a misguided goal. It will likely be much cheaper just to pay for that vacation. Of course if you don't mind spending quite a bit of money on other travels, you'll be able to get your "free" trip eventually.
