Delta Air Lines Quietly Raises Some SkyMiles Award Redemption Levels; Lowers One

FlyerTalk members are reporting that Delta Air Lines has quietly increased some of the medium-tier and high-tier award redemption levels by 5,000 SkyMiles per round trip as of September 1, 2012.
The changes in SkyMiles redemption rates are shown below in yellow.

Interestingly, all of the highlighted award levels increased by 5,000 SkyMiles per round trip, except for the high-level BusinessElite award redemption to Southeast Asia, which was curiously reduced by 20,000 SkyMiles per round trip.
While the changes seem minor at most — low-level SkyMiles awards are unaffected by the adjustments — some FlyerTalk members are angry, alleging that Delta Air Lines did not announce these changes, while others portend that this is only the beginning of further changes to come for SkyMiles award redemption levels.
