Mile-High Misstep
Traveling by plane can be fun, but this photo proves it can also be a disaster. A person in front has draped their hair over the headrest, covering the monitor behind.

Other etiquettes include keeping your seat upright during meals, respecting personal space, avoiding loud conversations, and not using strong-smelling foods or perfumes.
Passengers should also refrain from kicking seats and should always be mindful of their behavior. And yes, a customer can be offboarded for inappropriate behavior. Airlines have the right to remove disruptive passengers who refuse to follow crew instructions or pose a threat to safety.
