Hello! I have a full year of travel ahead of me, and I have traveled already. I think I am only enrolled in USAirways' program (I had America West, a long time ago), although possibily in United and American. Anyway, please help me sort this mess:
1. I traveled PHL to DFW in February, forgot to give my FF #. Can I still claim them?
2. In July I traveled PHL-LHR-CHP, then CHP-LHR-EDI, then EDI-LHR-PHL on BA. How do I claim these miles? Which airline FF program should I use?
3. I am planning a honeymoon for summer 2006 PHL-Hawaii, then Hawaii to Austrailia. I plan to use my AMEX points, however, I want to potentially use my FF miles to upgrade, or to trade in for furture travel.
4. I have a few other trips planned for this upcoming year, including Las Vegas (2x) and Arizona, prior to the July honeymoon. Which airline(s) should i purchase these tickets on to get the most out of my FF program?
I have always used USAirways for all my travel, but since I will be using Quantas and have traveled on BA (and plan future travel with them as well), I am at a loss as to where to start.

TIA!
