Worth getting a membership for the time between now and your flight and creating the alert. Every time I got this upgrade it was because of EF notifying me that O became >0. Never wasted anytime and called DL to process the upgrade.
Some agents might have difficulties doing it because it often requires them to switch the DL flight number to the AF equivalent before processing the upgrade. Some know how to do it, some don't. Don't hesitate to hang up and call back.
