A Virgin Australia flight attendant has revealed a little-known seat feature that solves a common problem when flying.

The cabin crew member made a TikTok video showing a hidden button underneath the armrest of the aisle seat that can offer passengers extra wiggle room.

The aisle armrest is usually locked in place - while the window and middle seats feature visible buttons on the side so passengers can lift and lower their armrests.

However, the air hostess revealed the “special” button that’s hidden on the underside of the aisle armrest, near the hinge.

The feature allows aisle passengers to raise and lower the armrest - making it easy for them to slide in and out of their seats during flights.

“Have you ever struggled with the aisle seat arm rest? Struggle no more with this seat hack,” the airline said.

“Press this special button and lift the arm rest. Problem solved. It’s a life changing hack, that’s for sure.

“Try this out on your next flight.”

When seated, passengers are required to keep the armrest down to avoid spilling out into the aisle in the event of a turbulence.

The video also shows the flight attendant getting the handle of her carry-on bag caught in an aisle seat armrest - a common issue many passengers face when boarding or disembarking the plane.

The clip has been viewed more than 28,000 times - with many travellers saying they had no idea the button existed.

“Thank you! I can undo this and relax in the air,” one said.

Another shared: “Thank you! I will try on my 14 hour flight and have a wider leg room.”

One suggested: “More people need to see this.”

While another added: “The bag getting caught on the chair is so real.”

Meanwhile, one revealed: “I’ve known about this for ages. I saw an air steward do it once. It made getting out of the rows way easier.”
