I have generally been very pleased with the handling of the priority baggages by CX, however, at some airports, it is not always the case. At HKG,NRT,TPE and BKK my first class tugged luggages came out always among the first. But even if there are only a handful of first class passengers, I think CX also adds first class tugs to their Marco Polo members, so there seems there are alot more first class tugged luggages than the actual first class passengers.
