I did my share of nonrev travel in a previous life when capacity was better and domestic first class upgrades still happened...
Anyway, I thought the purpose of the "not discussing" rule was to not upset the passenger next to you that they paid lots of money and you paid nothing - especially in premium cabins? Back then, there was no Flyertalk
It is a whole new game now with the limited capacity but also the availabiltiy of information on places like FT and at our fingertips when we travel.
