Showing IDs would work, but also training employees not to assume a warning is a glitch would have prevented him from boarding. If they took the time verify that the original person had already scanned their ticket, they would have noticed something was wrong.

EDIT: this is assuming that the warning is not routinely ignored (i.e. there's actually a bug in the system and it would slow down boarding time since it happens so frequently.) If that were the case... they should fix their system lol

It might be a generic "beep" error that a dirty sensor or paper would normally indicate. People get used to false positives quickly and start ignoring them.

Maybe it was a different alarm with a distinctive indicate that "I read this fine, but it's a duplicate" and they would stop and start checking the ID.

Apple isn't the richest company on earth because they pay for flights like chumps.

Formerly, it seems.

I wonder how quickly companies move to let the employee go after something like this. Do they offer to pay for a lawyer, or just quickly drop them as soon as there is an investigation started.

They could probably make a joke about "our accountants know how to think outside the box" but that probably wouldn't go very well at all.

If that were the case, I expect it would show differently. There was a whole thing in Seattle where someone got into accident that left their passenger dead, they escaped the hospital and headed back to their home country, while their employer kept them on the roster under "administrative leave."
