Just got off of flight 374 (SAN-IAH). Noticed that 1B went out empty. The Customers Upgraded info First Class showed:
SYF, R. 1B

As we pushed away from the gate, I mean right before the door closed, the list showed Swa, C as waiting for an upgrade. Obviously SYF did not show up. Even after the flight landed, it still showed SYR as having received the upgrade but he/she was not on the flight.

thoughts?

If he/she was not on the flight, shouldn't Swa, C have been upgraded?
