I have always found economy rewards quite easy to find, both domestic and international, even looking at large redemptions, like 8+ international to popular destinations. Only problem is, I think economy redemptions are a waste of points, which I believe is the consensus with most 'in the know' FF's. I've never really had a problem with business redemptions domestically either. Like most, I want to use my points for long haul business rewards, which appear to be extremely rare, especially if you are looking at more than 1 seat. There are rare occasions where you chance upon some great seats, but for the most part, they are hard to find and you end up trying to plan your trip around when and where you can get business award seating rather than the attributes of the destination. I also find that the majority of business award seating isn't even available on Qantas metal and you have to fly with partner airlines, with majority availability on non top-tier partners.
I, for one, would rather spend more points to actually be able to spend my points. But it seems to me like Qantas is trying to encourage people to spend their points in economy rather than business+. Looking at the table in original post, a trend for less points and less money in economy. More points and more money in business (domestically), less money internationally.
Up to 10x increase in long haul business availability. This sounds awesome, but the reality is 10x zero is still zero and with a trend towards 2 engine planes, the business cabin is going to have less availability, not more.........and is that up to 10x per flight or per year?
At the end of the day, Qantas is, just like every other business out there, more interested in profits to shareholders than their customers. Any changes to the current award scheme will come with that thought in mind. The PR spin doctors will try and market any changes as positives to us poor customers, but it won't deliver. Only hope keeps us hooked.
