We all know (or should know!) not to stick our hands down inside seat back pockets. Those are bigger germ farms than the monkey in Outbreak. All seats have them though, usually even bulkhead seats. So those seat back pockets don’t differentiate one seat from another.
The question is, if you want to avoid the plague, which seats are the most infected on an aircraft? Which ones do you want to avoid?
The answer actually seems obvious once you think about it: Window seats are dirtier than aisle seats. There’s more surface area that gets dirty, and it’s harder to reach.
The closer the seat got to the window, the dirtier it was. The aisle seat, however, appeared to have the least amount of dirt. …[T]he reason it has less dirt is because it is cleaned more often than the other two seats due to the proximity to the aisle.
An aisle seat is always better and I hadn’t even considered cleanliness issues when explaining why.
