In theory, more aisle space would put more passengers onboard faster, because people could walk two by two. With more room, getting on a plane might be easier for families with children and people who are handicapped.
This is all really nice in theory, but the sliding seat would also require a totally new boarding system that would call for less seating anarchy than the status quo allows. And it would probably render the aisle seat the worst place to spend a flight. Plus, considering how long it’s taken many airlines to add inflight Wi-Fi, it’s probably not a top priority to address seating issues.
So, OK, the sliding seat is just never going to happen. But even if it did, could it work? Or is there a better solution for speedier boarding? [Core77]
