FT is really the best source. As for strategy, I suggest you do what I do:

1. I try to bank my miles in one airline's program. (AA, but your home airport and where you travel will influence your decision. Then try to fly that airline and its partners whenever possible.)

2. Nevertheless, I wouldn't pay an unlimited premium for AA miles. If AA wanted $1400 for a ticket that somebody else was offering for $900, I'd fly the latter. Have some rule about how much premium you are willing to pay.

3. For the above reason, I have also joined other programs (one from each major alliance, plus SW, plus an airline in India that I fly often). If I must fly another airline, I like to get miles even if not in my favorite AA account.

4. Get a credit card that earns miles for my primary program. There will be an annual fee and somewhat higher interest (so don't carry any balance here).

5. Keep looking at other miles-earning opportunities: cell phones, isp's, shopping, banks, hotels, etc.

6. Try to get elite status in your primary program. That way you earn extra bonus miles, besides other benefits.

7. To maximize miles/dollar, learn how to look for cheapest fares.

8. If you are comfortable with being and looking really insane, then start doing pure "mileage runs (MR)", ie, flying with no purpose other than earning miles. Mind you, if you do anything in your destination city other than perhaps using the rest-room, the purists here will refuse to let you call it a "MR".

9. Keep participating in FT forums. They will help you with all of the above.

Good luck, and welcome to FT!
