A DM who chose SWUs for both PM Choice Benefit and DM Choice Benefit would have 10 SWUs to use in a year.
Going forward, the DM will earn a maximum of 4 per year.
While the fare class restrictions are appreciated, I have now been knocked down from 5 roundtrips to just 2 roundtrips p.a. Ouch. (N.B. I have used SWUs for 8-10 one-ways per year for the past several years.) Happy to be corrected if I am misinterpreting.
For me, when you combine this with SEA-JFK upgrade restrictions, this is a net negative.
