I've gone 6/6 on Business Class upgrades since earning Elite status ...

Sat, 12/5 @ 12:35 pm - BWI-BOS: Went up to counter an hour before the flight, new boarding pass already printed for me (BC left full).

Mon, 12/7 @ 12:30 pm - BOS-BWI: Running late for the flight, already boarded when I got to the gate, asked about upgrade, gate agent processed it for me (a couple BC seats left open).

Fri, 12/11 @ 12:35 pm - BWI-BOS: Went up to counter ~45 mins before the flight, gate agent told me that it wasn't a problem but told me to come back since his computer was giving him issues, came back 10 mins later, and he printed out my new BP.

Sun, 12/13 @ 8:30 AM - BOS-BWI: Went to counter ~50 mins before flight, told me to talk to the gate agent who had a couple upgraded BP printed out.

Sat, 1/16 @ 12:05 PM - DEN-ATL: Didn't think I had a chance at an upgrade, completely full flight due to a canceled flight to MKE, only 4 BC seats left earlier in the morning. While checking my bag (~55 mins before flight), asked about how many BC seats left, looked at me weirdly and told me that I was already in BC and printed a new BP for me.

Sat, 1/16 @ 8:45 PM - ATL-BWI: Went up to gate agent ~65 mins before flight, she quickly sent me away telling me that I needed to come back 40 mins before. At the 40 min point, she made an announcement offering BC upgrades for $49 and motioned me over, handing me a BP she had printed.
