I'm trying too to use award nexus and i think that is a very helpful tools for frequent flyer.

you can see in a calendar the flight availability !!

Unique negative things is that the query take a point and this reduce the possibility to find more options for flight. All membership levels is connected with points that is used to make query.

Other tools, like kvstools permits infinite query and this give to you more options in search.

I suggest to award nexus to implement a membership level with infinite searches.
