I had one of my more unpleasant AS customer services experiences with an agent in Seattle and a slightly overweight bag. I had weighed my bag at the scale across from the AS counters and repacked already to get below 50# as indicated on that scale. When I went to check it in, it came up as 52#. Agent was completely unhelpful and unsympathetic, basically just saying "oh, yeah, those scales are wrong" and telling me to step aside and repack. Kind of seems like the airline should give some credit to the scales offered right next to its own check-in area to enable customers to avoid that sort of hassle.
