There is a plethora of information out there to help you with point/mile redemptions... that's what this whole forum community is about. There are also travel blogs like "The Points Guy", "Frugal Travel Guy", "Loyalty Traveler", "View From The Wing", the list goes on... you'll have to put in some time to research these.

Alternatively, and definitely not to be abused, you can arrange travel for a "friend". What that "friend" does to return the favor is up to you guys. *hint*
