And what you repeatedly do not get is that the OP's original premise was:
"I would just like to address this common fallacy that using your FF miles for economy fares is not getting the best value out of them"
and then he went on to talk about TATL examples (much like yourself).
My premise has been that the argument is flawed because it has never been a common fallacy around FT, perhaps in the OP's mind, or yours, however the common thought on FT (which is where we are and which is perhaps the greatest repository of FF knowledge on the planet) has in fact been that they are a poor value for domestic or "short haul" flying vs. long haul flying unless there is a compelling reason to use them for such (last minute business/emergency/death/whatever).
No relevence to you? Doesn't really matter as in fact you keep skewing the argument towards something which I both never meant nor ever intended, I also doubt it would not apply to Luanda either, but no one was talking of such.
The fact remains that unless one has a very compelling reason to do so, one will find that using miles for short or mid haul travel is generally a poor proposition.
