Kids on airplanes?

I recently came across this video of a kid (probably about 2-4 years old) crying as they were getting on an airplane. The man filming the video on his phone was probably 60s-70s and the caption said “this will never not be funny”. As the child is crying in his moms arms boarding the plane, an older woman sitting behind the man screams back at the crying child in the same volume and pitch.

There were thousands of people agreeing in the comments that airlines should ban children, some saying only children under a certain age (most agreed on age 5), from traveling on airplanes. What’s your personal take on this?
