A male passenger recently expressed surprise when a flight attendant announced a strict rule: “No one is allowed to use both armrests when seated on the airplane.” He, like many, had always assumed that the middle seat passenger held a unique privilege to both.
This announcement came from a flight attendant on an American airline. “The flight attendant clearly stated that no one could place their arms on both seat dividers,” shared the traveler, known online as Littleike.
Furthermore, the flight attendant provided specific instructions on armrest usage: passengers in the right-hand rows of the aircraft should consistently use the right-side armrest. Conversely, those seated in the left-hand rows should utilize the left-side armrest. The armrests bordering the aisle, the flight attendant explained, need to remain unobstructed. This ensures smooth passage for both passengers and crew, particularly when they are moving through the aisle or using service carts for food and beverages.

The flight attendant also indicated that they “would address any conflicts arising solely from disputes over armrest space.”
“I felt guilty for those in the middle seats because they couldn’t use both armrests,” the man admitted after hearing the flight attendant’s directive.
This traveler’s account quickly garnered hundreds of comments, highlighting the perennial passenger interest in the etiquette of airplane seat armrest usage. According to social etiquette experts and frequent flyers, an informal code of conduct often exists onboard. Window seat occupants typically benefit from leaning against the fuselage for sleep, while aisle seat passengers enjoy the advantage of more legroom. Consequently, the middle seat passenger, facing the most confined space, is often unofficially granted the right to both armrests. Many have agreed with this unspoken spatial arrangement on airplanes.
Many people agreed with the flight attendant’s system. One passenger said, “I agree. It’s annoying to squeeze past people.” These people put their arms on the aisle armrest. They also lean into the middle.
Mary is a flight attendant. She works for a big US airline. She often sees a problem. Passengers in window and aisle seats take both armrests. This leaves the middle seat passenger with no space.
A survey was conducted. British Airways did it. Almost 30% of passengers said something. Other people taking their armrest space was the most annoying thing about flying. But, there’s no official rule. No worldwide rule about using armrests on planes exists. Each airline has its own rules. So, unwritten rules often guide armrest use. But, airline rules can sometimes surprise you.
