Tried to use this lane with a friend on the morning of 23/12 and it was pretty full of what looked like inexperienced fliers. Got moved over to the employee line.
Just now after my return flight I saw that it was absolutely jam-packed; no wheelchairs.
Shame, as the regular premium line dumps the elites out behind the kettles who can't comprehend that a 54 oz bottle of PertPlus isn't allowed in their massive carry-on. Maybe I should just start connecting out of DCA.
