That would be my guess too. As mentioned earlier in this thread, some have noticed that when an upgrade clears, EF still shows the inventory as available while the upgrade processes for a little while. If you log on to AA.com, the itinerary will be unavailable, but if you call, the agent will tell you the upgrade is going through and can finalize it with you. Once it's fully processed, EF will zero out the inventory.
