Has anyone else experienced the awkwardness of trying to get into a priority booking line when boarding? Yesterday when leaving CDG we approached the line, after leaving the lounge, and the "line" for business class passengers was rather wide, and appeared not to be moving. Yet, the sign for priority boarding was being held high. We assumed that the other passengers in line were traveling economy, so excused ourselves, and were then told by another passenger that we "must be special". I still feel embarassed by this, although we apologized and told him to please go ahead. He then responded, as his partner rolled her eyes, that they were not in that much of a hurry. I still do not know if they were in the line appropriate for their tickets, but I have certainly learned that next time I'll ask first. By the way, the boarding had been delayed by almost an hour, so those of us in the lounge had not been in lines like many others. Any feedback on this would be appreciated. Fortunately, we have no planned flights for several months.
