With the expansion of Starlink Wi-Fi on United flights, the airline decided to make its long-standing headphone request an official requirement for all passengers.

United Airlines may start removing passengers who refuse to wear headphones for music and videos on flights, thanks to a new policy. The rule, added on Friday, appears under the carrier’s “Refusal of Transport” section and specifies that passengers must use headphones when playing any audio or video.

United Airlines has quietly updated its “contract of carriage,” adding a clause for passengers who refuse to use headphones.

United Airlines added headphone language to its refusal-of-transport policy, giving the airline authority to deny boarding to passengers who play audio aloud.

Somewhere on every flight, someone is playing a game or blasting music, reminding the rest of us why headphones exist.
