You did not say in your post that you were trying to obtain a higher status, need the miles for a specific award or anything else, so it sounds like you are just trying to burn the voucher, and are asking for help doing so. That's not what a mileage run is all about. If I'm way off then sorry, but since you are new you may not be aware of how it works. There are a lot of sticky-posts at the top of the forum that tell you the "how's" and the "what's", the other thing to look at is the mileage runs threads that have already been posted on the board.
Do a little research and start using the recommended web-sites and tools listed. Post good fares you find, share what you learn. And above all else.... Check the Mileage Run board for posted mileage runs daily!
Good luck!
