I’m giving this a shot (Gold -> EB Gold -> *A SEN).
applied for EB Sat pm, request for passport and status/activity received Sun am (and replied at same time).
I *may* get *A SEN naturally for 2025 so this could well be a means to get all three alliances for 2025, if I do the five SAS flights needed. There’s no way I’ll properly benefit from that (only a leisure flyer) but, well, it’s the challenge.
