Thank you for your more ore less discouraging opinions. It made me think over my itinerary and I actually changed it to ZRH-SFO, SFO-MNL etc. with a one night stop-over in SFO. This routing in Delta T-class was actually $ 60 cheaper than my first itinerary. And with adjusting my NWA flight from SFO to a Thursday, I saved another $ 60 in Q-class… ^ :-:
