I didn't even notice that the price for each generated mile had gone up 50%. So now to create 100,000 bonus miles the cost comes out to about $1,640, or 1.64c per miles. And you don't have as much flexibility in making sure the miles end up ONLY in the accounts you want to top up (unless you want to top up 2 accounts, then that's fine).
50% more expensive and much less flexible. I think I'm giving this a pass too.
