re "the customers themselves will be responsible for having their bags scanned during drop off", Frontier already has this technology in place at some airports. I had the experience of successfully using this and thought it pretty cool. However, I also watched a number of passengers struggling with issues such as: after whisking the bag 10 feet up the conveyor belt, the bag comes back but with little explanation, thus requiring an attendant to help. There was one attendant for a dozen or so bagdrop stations, and many customers were waiting for her, poor thing. Hopefully that is just teething problems.
