NCL has always been cursed with more than a reasonable percentage of chumps in security, even when compared to the large proportion that seem to inhabit the industry generally.
Swissport pax handling has always had a reputation for being exceptionally poor over the years. Last time I had to endure their 'handling' services on a regular basis, it was disappointing to see that the ramp operation had headed the same way.
