Just thought I would add my experience. I booked BNE - SIN return through VA codeshare.
Did not get an email upgrade offer.
I emailed Etihad and asked and then they sent me an offer email.
I bid on the SIN - BNE leg only. I think min was around $380 or $400 something like that.
I bid $455. I am not an Etihad member nor did I bother to join.
Didn't hear anything from them so thought I didn't get it.
Went to check in and I asked them how much for an upgrade Economy to Business and was quote $885 (or something like that).
I declined.
Then she printed out a Business boarding pass for me - I was pleasantly surprised.
So I won the auction but was not notified.
