Quoting vikkyvik (Reply 3): Same thing happens with some Skywest and Southwest (both end in SW):
With both Southwest and SkyWest registering blocks of SW suffixes, there was in essense, a scramble, for the remaining blocks of numbers. However, with the newer birds, Southwest suffixed WN and SkyWest suffixed SK, which has suited each other better, really. (SkyWest can't suffix OO since the letter O is not allowed in the last 2 digits of a registration.)
