I have met a number of cool people over my 1.5 years at FlyerTalk. In terms of what I have made monetarily, FT is a net loss dollar wise but the experiences I have had through all of the travels are what's worth while. For example, I wouldn't have gone to Europe 3 times this year, but for $1200 for 3 trips the experience is worth it and because of FlyerTalk I learned how to do it all while earning 60k miles. The 60k miles in turn got me about $4500 worth of tickets so one could say I made a profit of $3300, but for me I never would have traveled in Business Class around Asia so I would say that these tickets were an even break with the $1200 spent flying to Europe.
I look at FlyerTalk as the $120k my undergrad degree cost me in terms of what i have earned. It's expensive up front, but that degree sure yields some nice dividends in the long run and will take me places I may have never dreamed of going to 2 years of going to. one last thing i am grateful to FlyerTalk for is the fact that my passport is completely loaded within 2 years of getting it, to me that's an accomplishment at the very least.
