In addition to more wiggle room, Southwest’s improved seats -- which were designed by B/E Aerospace and unveiled yesterday at Hamburg’s Aircraft Interiors Expo -- come with a moveable headrest and extra space to stow your carry-on; they’re also super lightweight, and help make the plane more fuel-efficient by collectively reducing each aircraft’s weight by 200 pounds! That’s a Jonah Hill circa 2011-level of weight loss right there.
Before you get too excited, though, seat pitch will unfortunately stay the same, which means legroom and seat reclining wars will continue to go on. But at least, by mid-2016, there'll be wider Economy seats on Southwest's 737-800s, and by 2017, on its 737-MAX jets.
