I booked round-trip tickets to Japan from Miami back in July 2022. I used four systemwide upgrade for flights that had automatic clearing to business available which was confirmed when I booked through the agent. Recently a flight schedule change by American caused my scheduled flight from MIA-LAX to overlap with my scheduled LAX-HND flight.

American rebooked me for two days later than my original flight on a MIA-DFW-HND trip. We noticed that we were rebooked back into economy so I called. After three calls and 10+ hours with agents it was concluded that when the agent rebooked me, my systemwide upgrades fell off and that unfortunately because the original expiration date had passed they could not reapply them.

So essentially, I lost my upgraded seats and my systemwide upgrade due to their scheduling.

Anyone else ever had anything like this?
