Slightly OT, but there is one baggage delivery improvement I would like to see at all airports.

At some airports (can't remember where or even if it was in the US), a notice comes up on the carousel when the last bag from the flight has been offloaded. I'd like to see that everywhere.

It's a real drag when sometimes the belt stops for 10 minutes, more bags come out, it keeps circulating, no one can actually tell you if all bags for the flight have been off-loaded and it's time to go file a claim or if there's still more to come.
