I flew home on Friday from MCI and their was a short line for Premier Access check-in so I used a kiosk. It was a newer design than I've used previously and was oriented in portrait style. As I started using it, a you UA employee approached and asked if I need any help. I told him that I was just trying to get a paper BP and he said "yeah they are buried about three extra clicks deep now because we are trying to encourage people to go digital". I had some time so engaged him a little bit and we had an interesting discussion about the self-service push from UA (and other airlines) He said that UA is pushing towards the role of an on-premise agent being "special assistance" only and check-in, bag tag and drop,etc all being self-service/digital. Sounds to me that paper BPs have a finite life span.
