Please stay on topic
As Sean points out, the thread itself, under its original topic heading, is relevant to the AC forum.
However:
a) there have been many past threads on this topic, and to make it easier for other FlyerTalk members to find the relevant information, please do try to search them out rather than opening a new one.
b) the subject of this thread is "SE & E Access to United Economy Plus Seats", not "here are the benefits of the UA MP program and how to apply for elite status in the UA MP program." Comments on this subject should be posted to the UA MP forum on FlyerTalk.
