Great to hear we provided some value here, although I will point out that contrary to popular opinion, QF points aren't worthless. The key thing about them though is you need to get even more creative to make availability "appear". Whereas with Aeroplan sometimes you need take circuitous routings (i.e. stopping over in Europe) with QF you need to go even further, booking multi-city awards involving one or more of QF's mistresses (i.e. CI) to make something "appear". All of that said, yes, buying points can be an exceptional value particularly if you have an itinerary in mind with business saver availability!
With Frankfurt, there is a Gold track line if you're in business class that lets you skip the queues. That being said, yes the airport is annoying, it's a cavernous maze that requires it's own map. I can't tell you the number of times I've been questioned by German Federal police for going down random hallways that are supposed to connect me to other non-Schengen terminals. For a capital city airport and for the largest airport in Germany, yes it is a disgrace. This is why I prefer flying into a city like Zurich where the airport is compact, the lounges are nice (including a terrace) and the airport is clean. Zurich also has the benefit of being the hub for Swiss with fellow Star Alliance partners like TAP, SAS and SQ flying into there, to say nothing of EK or EY. Even Heathrow with its stupid APD has redeeming qualities like the lounges and relatively straight forward connection process.
