If you are looking to top off an account to get to that next award level or just trying to consolidate orphaned frequent guest accounts I would suggest taking a look at InsideFlyer.com’s Mileage Converter tool.

It basically has two good features to check what the best conversation rate is for your desired transfer.  The features are:

1. You can find all the available conversion paths between any two programs by following the instructions under “Calculate a Transfer”
2. You can find ways to transfer a specific amount of miles/points into an account (i.e., top up) by following the instructions under “Find Top Up Options”

Bottom Line

The next time you are needing a few extra miles or points for an award, check out the available transfer options with all of your orphan mileage and point accounts to see if there is a better transfer option.
