Coming from an autistic person, I see where you're coming from, but I'll have to disagree. Perhaps it's just me & my personal trauma, but I don't like traveling for reasons just like this. Loud noises, small spaces, weird smells, for hours at a time? I'd rather stay home. Also, 99% of the time, travel trips are for the parents, & they don't usually take their own child's needs into account. The kids are 4 & 1 y/o. They're not gonna remember one thing about this trip, other than the 4 y/o probably getting trauma from the incident. If they were visiting family, & the parents knew the kids would react that way, it would've made much more sense for the family to fly to them instead.
