My offer at check-in for SFO-ATL was $314 for only the return leg of an RT itinerary. I was 4/17 on the UG list for 5 seats and cleared at the gate.
I know FCM is happening though. I missed the outbound ATL-SFO by a single seat (was 1/17 on ATL-SFO) because there were 5 open FC seats at check-in and then 3 at the gate. Round trip FCM was $414 on a U/X fare, so someone with a higher priced economy ticket may have paid less.
The thing is, I wasn't expecting an UG to/from SFO as a GM, so even being close (and getting the UG on the way back), was a great surprise.
