I believe, and know someone will correct me if I am wrong, the new UA will re-book you into your ticketed fare class. The old UA used to just put you into the most readily available which was frequently "Y"
They have always supposed to have put you in the original and often just forced Y because it is easier/faster. Some still do, though getting the old fare class assigned is easier these days, I think, so that may have something to do with it.
