Welcome in the modern world. Companies worldwide will try to cut costs, not only RYR. I have been working at Amsterdam Schiphol airport for 12 years now, and in those 12 years, I have seen an explosion of the numvbers of self check-in desks/machines/bagage dropoff point, in all colors and with all logos.
Yeah, it will mean a loss of jobs, but that seems to be inherent of " progression", just like the invention of steampower, automated looms and glass/automated cockpits meant less needed people to do the work...
