AC158 last night. (Dreamliner)
T-24 - no offer
T-12 - no offer
T-6 - no offer
T-1 - offer. To PY $241. To J - $579.
Flight left 60% full, and both front cabins weren't even half full.
Had I been given the offer earlier I would have taken it, but given that I was close to takeoff, had already had a few drinks and knew I was just going to pass out, I skipped the offer.
Datapoint - this was actually on a AP ticket!
