I've heard everyones story about being told that upgrades can only be done by computer but I've had an enlightening experience. I am on a flight to ORD on Monday and today is Thursday, 4 days away. I didn't clear on my Plat status on Wednesday. Looked online to see if there were F class seats and there was one. Called, asked about it and she did a manual upgrade for me. Even looked on-line and the seat was changed to F from V. Was this an error or an extremely helpful person?
