To recline or not?
While airline seats are designed to lean back for passengers' comfort, it's usually a less-than-optimal experience for the person who gets the back of a chair cramping their space.
One passenger on a recent flight asserted her right to recline in a heated argument caught on video that went viral.
"I'm allowed to put my seat back," the woman angrily declares multiple times.
The argument triggered an age-old debate on social media, with some saying it's important to be respectful to the passenger behind you - but others saying if the seats weren't meant to be reclined, the airlines wouldn't have designed them that way.
