I've only just really got into the detail of this issue, as it affects me, and I'm knocked out!
Looking at SIN-JNB and SIN-MAD, for example, for March 2012. Prices are only slightly higher than this year's bookings (maybe 10%), but the tier miles are exactly 50% of what they were this year.
If Emirates thinks I'm going to pay double for Gold status in 2013 over what I paid for Gold status in 2012 they have got to be kidding hugely.
I'll just revert to my Star and One-world Gold statuses (I'm sure I've said this before somewhere, so please don't get too upset about it).
