If you want to learn about travel hacking and have someone help you, I highly recommend Brad over at http://www.richmondsavers.com/
A Mustachian couple, they write about travel hacking and give free coaching lessons:
http://www.richmondsavers.com/free-travel-rewards-coaching-program/
Literally free. Brad will email you, chat on the phone with you for 45 minutes, etc. helping you out. All they ask is if you do sign up for some cards, use their referral links (but they don't push any particular thing).
I don't see how that's sustainable time-wise, so I'd jump on it now if you're interested. ;)
@arebelspy: Thank you very much for this extremely positive mention of my free travel rewards coaching program -- that was really kind of you!!
I got a kick out of the "I don't see how that's sustainable time-wise..." as you are almost certainly correct in the long-run. For now it is working out great, but yes, in the long-run my time eventually becomes a constraint.
But until that day comes, this is a completely free (no gimmicks) service where I'll email with people and hop on the phone to answer any questions and help you plan a cohesive travel rewards strategy moving forward.
I like to look at this coaching as 'travel rewards for regular people', as I know how complicated and daunting it can be for most people to get into this concept, so I try to make it fit into the regular framework of your life.
Of course the usual caveats apply that you have to pay your credit card bill in full and on time every single month, and you probably shouldn't do this if you're just starting your credit history or are buying a house in the very near future, but other than that, this can really be done by anyone!
If anyone is interested, I'm happy to help, so just sign up at the link above or just send me an email: brad (at) richmondsavers.com
