It's been a long time coming.
Anyone who has flown with young kids in recent years knows it's not uncommon to find that your preschooler has been assigned a seat half a plane away. All too often, parents are told it is up to them to ask someone to switch seats.
In one case I wrote about, a mom with autistic twins was forced to go to her senator for help. I've seen other parents offer to buy drinks for a passenger, if only they'd switch. Congressman Jerrold Nadler (D-NY), a member of the House Transportation and Infrastructure Committee, was hearing numerous complaints from his constituents. Even one of his congressional staffers reported the same experience.
