I messaged AS today, and they said that as of now companions should be able to receive complimentary upgrades with an AA OW Emerald passenger (up to 5 days prior space permitting). So I’ll see what happens when we cross that threshold for our return flight if there are U fares available. They said hopefully AA will update their site soon to reflect this and remove the “later this year” clause. Fingers crossed, but I’m not holding my breath because it didn’t work as of a couple days ago.
