The way I read it, if your membership ceases between now and the date of the SWP program ceasing, you can still get Zone fares, but after the program ceases no-one gets the Zone fares (not even lifers).

As recently as a month ago I was talking to a 1K reservations agent who was trying to sell me the benefits of SWP as "UA is mostly phasing out Senior fares" and I told her then I thought SWP was pretty useless. Perhaps UA finally got the message
