Hello all. I am a miles junkie and try to earn miles with anything. That is everything but traveling. I have maybe only 1-2 work trips a year and maybe one personal, so I strive to earn miles for personal vacation. I enrolled in many airline FF programs as I found ways to earn miles for each. But I feel I need to consolidate some programs. I want to combine programs for airlines in the same network, such as OneWorld and Star Alliance. Is it true you can spend miles within a network, and also earn for differnet airlines in the same network? Here are my current totals. I want to keep a representative in each main network. So I believe Alaskan, Air France, and Emirates need to go. Advice is much appreciated.

AA - 3275
Alaskan - 1100
Air France - 1000
Delta - 3735
Emirates - 500
Frontier - 10,522
United - 10,419
