things which seems to be in common: Flight number: AC 8742 (printed flight) AC 874 (my flight)

levenshtein distance of printed name: 12, m = 15, n = 12

boarding pass: https://imgur.com/56ZRhOI

Seems like the only thing in common is that the boarding passes where probably printed at the same time.

Any suggestions what can possibly go wrong when a computer system prints a boarding pass, based on the scanned passport?

In case you feel like that could be your lines of code, let us know :)
