Do I need to even mention how annoying this process is after a long flight. I just want to scream "Step back so we can all see not just you"!

Why not have the airport install baggage claims that are large enough to accommodate all of the luggage from the largest plane they expect to land? That way there is plenty of room for everyone to watch for their luggage.

Good identification of a problem. I disagree with solution. You write that the "airports... inform passengers that everyone is to stand..." Such an arrangement would depend on an 'enforcer' or in this case, a persuasive supervisor. Or, in reality, it depends on self-compliance. Not much of an improvement. How about zapping people's feet, like dogs within an electric fence?

good idea! I don't agree that using an "enforcer" is a bad thing. Enforcement is being used a lot, specially at airports, and it works. And in this case, it would actually benefit the passengers.

Regarding larger baggage claims - I think this is just about making efficient use of space & money. Also, the larger the claim, the longer it takes till each piece of luggage makes it's round, so that could fire back too.
