LifeMiles is one of the best frequent flyer programs for advanced miles and points collectors because they have hidden deals and there are tricks to reduce the price of awards.
I once heard the head of the program give a presentation where he called miles earned by flying “bad miles” and miles sold to partners (like banks) and to customers “good miles.” This frequent flyer program is basically the consolidator for Star Alliance airline excess premium cabin inventory. Lots of ways to get their miles cheap, and use them for seats that their partners aren’t going to sell for cash (saver award inventory).
