My two cents worth...
Overall, the majority of changes are not a big deal to me. There are, however, some glaring mistakes in tables and the system is far from "simple" despite the claims by QF otherwise. The cutting of SCs on OW airlines by 50%, is not, IMHO, in the spirit of the OW alliance.
But my biggest beef??? What continues to astound me when QF implement changes, is how poor the execution is - the other recent example would be the new booking engine. When making these sorts of sweeping changes, the focus should be on getting it right from the get-go. When they fail to do this, they create a backlash. This is just another example.
Your customers should not be pointing out errors in tables to you. Your calculator should not return "no flights found" when trying to calculate earn under the new system - on any route, let alone ones you actually service like SYD-JFK and MEL-LHR. BA have a fully functioning calculator that shows ALL OW routes, why can QF not get this right?
Under a non miles based system, how am I supposed to work out how many points for the routes that QF don't fly without a degree in geography and aviation economics without a calculator??
