An interesting question! It may seem to some that the addiction has it's costs but I view it as a pre-exisiting adddiction so being on FT has only enhanced it.

Yeah, maybe I had no firm AKL plans and me spending $1500 wasn't in my budget at that moment, but c'mon, given that misprice was 10% of it's normal price that trip and many others, like the BA $20 WT+ special, have literally saved me tens of thousands on travel. I'm detailed oriented but not to the extent that I could come anshwere close to putting even an approximate dollar figure on how much I've saved during the years on FT.
Beyond the immediate dollar figure however is the intangible advice and information garnered from my time here and as others have said that is priceless.
