mobile boarding pass QR code changed between check-in and flight?
I had a flight recently where I took a screenshot of the mobile boarding pass the night before the flight. The next day there were some gate changes, nothing major. When I tried to board the screenshot of the QR code didn't work, and I had to generate a new boarding pass at the gate to board. I compared the old vs new boarding pass and noticed that the QR code had changed slightly.
Anyone have any insight into this?
