What if it's diverted for weather? What if there is a medical emergency on board? That happened the last time I flew with my son, and an adult woman was screaming her father was dead. My son of course wasn't hurt or in danger but he was really scared. What if they spill all their food? Feel sick? Puke? Need to go to the bathroom badly but all the bathrooms are full? Too many things to go wrong and unnecessarily stress the kid out at that age. 10? Maybe. Depending on the kid. Not 6.
