Any kid may do this in an unfamiliar environment

1. Parents need to be prepared with distractions
2. Normally have an escape plan. For example if you were going to a restaurant, decide ahead of time which parent takes the kid outside
3. Since there is no escape plan once you’re on an aircraft, don’t take a little kid flying if at all possible.

We only took a little one once, at an age when nursing is a great distraction plus made him sleepy. Otherwise, we drove or didn’t travel longer distances.

The reality is any kid may misbehave in such a scary environment. You may think the parents are entitled or poor parents when they don’t do something about it but the reality is in an airplane your options are limited
