GUC's: The most bang for your buck
Newly minted DM here. I'm curious to hear everyone's thoughts when it comes to using their GUC's. I just recently, and successfully, used my 4 for my wife and I to fly KLM from LAX to CPT via AMS. But to get to my point/question, is that about as good as it gets when it comes to using them? I'm hoping I will continue to make DM status in the years to come and was wondering what other options I could use future GUC's on where I can get the most value out of them. I've heard horror stories about using them to SYD and even and other transpac itineraries. Europe even seems to be tough. I know I know it usually comes down to YMMV for each person. Anyway, just looking for some feedback and conversation.
