I don't have any outrageous experiences to report, I'm just curious. Would I as a NW Silver UG be treated differently than a paid F, or a Plat, etc? Sometimes when I observe interactions in the cabin, I start to notice little things... how often they come around for drink refills, whether they forget to bring a requested item, etc. I don't mean to sound paranoid. I'm just curious. I know on CO they identify CO* passengers who may receive special treatment.
