This is actually a significant and highly negative change for my travel patterns -- and not one you've called out (except in the table). The top of the range for economy awards in both the 1401-2100 and 2101+ mile band is significantly increasing:
30K to 40K for 1401-2100 miles
30K to 50K for 2101+ miles.
SFO is my home airport, and I switched my loyalty (after nearly 1.6M miles on UA, 16 years of elite status, 11 years of which were as a 1K) in October 2017 to AS. This was largely from the increased service offered by the VX merger, the mileage credit based on distance (as opposed to UA by ticket price, my company requiring lowest fare with little leeway for deviation, and my mostly domestic coach business and leisure travel), and these excellent award tiers.
The short distance ones are still a great benefit if you can get the lower end of the range. But where it will hurt is when we travel as a family (my wife and I, plus our three children = five plane tickets), especially when redeeming at the last minute or over holidays when tickets for cash are ridiculously expensive. The 25K unrestricted coach already became 32.5K on UA, so 30K for unrestricted coach on AS was still better. Because the earning rates are so much better on AS, it's still superior to UA overall. But 30K to 50K on this unrestricted coach is a huge devaluation for us.
