RFID that pairs with the app. When you find your seat, the app buzzes, dings, alerts, Siri yells at you, whatever. The boarding pass should be — and can be now — contextual. Like the map app. Overview when you start, but when you start routing, turn right in 200 yards…
I also print three copies of all boarding passes in addition to the airline app. One stays with a human being (in case the plane goes down, everything is at their fingertips) one in my pocket/passport for quick reference (the one I use mainly to navigate the gate, through security) and one in my case just in case.
All are hard to read because they are airline-first, not traveler-first.
Also, can you do something about article byline and dateline placement? Time, place and who wrote it matter. I hate scrolling around and finding it in tiny print. Sorry for the late reply; I just now saw you wrote this last month.
