For the past decade or so, airlines and academics have tried to come up with the fastest way to load a plane. For good economic reason: The less time airlines spend boarding passengers, the more revenue-generating flights they can squeeze into a day.
Every minute cut on boarding can save $30 per flight, according to a 2008 study in the Journal of Air Transport Management.
Some airlines load from the back of the cabin to the front while others load passengers in the window seats first and work their way in.
Now a Denver-based airline interior designer has a new idea to cut the load time: An aisle seat that slides away from the aisle and ends up on top of the middle seat, expanding the aisle space from 19 inches to 43 inches. So, then after boarding on each row is completed, the aisle seat is slid back into position.
