At DEN, they have manipulated the "Expert" lane to be right in front of where the elite and Clear lines dump after the ID check.

Also at DEN, prior to said manipulation, I've passed people in the "expert" lane who needed assistance on what to put into the bins.

In DEN, the "choke point" is the ID checks. Many times, the standard lines will snake around many times over since they don't have all of the podiums open.

Thus, any benefits of this lane system thing is rendered useless at DEN. But I'm sure the management there will declare it a huge success.
