In December Chicago passengers leaving the lounge were taken to the platform by red caps. Everyone else was told to walk to the boarding area.
When I mentioned that in the past passengers were led to the waiting area by an employee, I was told that they were not allowed to lead passengers during the current construction phase.
Since I have done this before, I knew that when I arrived at the waiting area, I needed to tell the attendant that I had come from the lounge. I was then sent to the preboarding area. Passengers were then separated into two groups: sleeper passengers and coach passengers. Passengers who had been waiting in the senior lounge and passengers needing assistance were added to this group. We were pre-boarded - sleeper passengers first; then coach passengers - all before those in the general boarding line.
