I R'd TFA.
Apply little reading comprehension: It was Kyle, the FATHER, whose passport was denied. NOT the kid's.
OP:
"... they chose to deny a young child access to the flight, in essence denying the whole family."
FTA:
"Little Kye’s passport has a crease on the back cover, which Gosnell says came from him accidentally sitting on the passport.
His passport was questioned, but not denied. It was Kyle Gosnell’s that was the real problem. It has a small crease on the back cover, and is overall weathered and worn."
If we're going to infer things then let's infer that the dad's passport was old-school and didn't even have an RFID tag in it since it was described as "[having a] small crease on the back cover, and is overall weathered and worn.
