I e-mailed Spirit airlines to see if I need to pay for seating assignments, or if they'd assign my 2 year old next to me by policy, and they told me to shell out the cash for the seating assignments. I thought that was a bit odd; it'd seem like you'd want to go out of your way to make sure somebody isn't sitting next to a child crying for their parents 8 rows away. As a paranoid father, I'd also like ensure my 2 year old isn't sitting next to Grabby the Child Predator.
Is this this not something airlines typically do by procedure?
