Yowza -- added this to the list. Thanks for pointing this out.

I've always used the real-time baggage scanning to my benefit on both UA and DL. When I am forced to reroute (e.g., IRROPS), it's always reassuring to ask where my bag is.

For example, I checked a bag MIA-IAD-SFO a couple months ago, and I was auto-rebooked on a much later IAD-SFO when IAD-SFO cancelled. I switched to a better IAD-LAX-SFO, and when I landed, the 1K desk was able to tell me exactly what flight my bag travelled on (not with me, but beat me), so I could go down there and find it with certainty.

Similarly, on a recent DCA-JFK-SFO on DL, we took a delay DCA-JFK and barely made the connection. On arrival at SFO, I asked DL if my bag made it, and they verified it was scanned as loaded on the plane, so I knew to wait around for the carousel to start running.

I'm going to miss this functionality if we lose it.
