Probably also impossible for E.C.Golds as well.
I see ZERO U inventory on expert flyer on or around the dates in question.
Doing it all in one go is not a problem. I'm just blue tier and have prevoiusly done this via the call centre as they were open jaws (so they hit you with an offline booking fee) but you can probably do it online too now.
Strange that you can't see any U inventory on LHR-JFK - normally there's plenty of space on that route. Maybe EF isn't showing good data??? Give me an idea of dates and i'll check via BAEC (although your friends can do this too as presumably they have a stash of BA miles - you can't use AA miles to upgrade on BA).
