How to turn your sweater into a comfy travel pillow on flights

A SLEEP expert has revealed why passengers should never buy a travel pillow along with a free hack for travelers to nap comfortably.

The TikToker showed his viewers how to turn a sweater into a pillow to support your neck muscles.

James Leinhardt said in the video: "When you get to the airport, do not buy this c**p.

"It's not going to support the 20 muscles and seven tiny vertebrae in your neck," he said referring to a standard travel pillow.

Leinhardt said his hack will save money and even space in your suitcase.

All you need is a sweatshirt and a hair tie.

"With the jumper you are going to be coming home with - because it's cold and miserable when you do - fold it, roll it, wrap it 'round your neck, get an elastic band or hair bobble and pin it together," he said.

"And now you have a beautiful neck cushion."

If you would rather wear your sweatshirt on a chilly plane and need something in a pinch, another TikToker shared their own hack.

In a video posted by Kate Spiers, a TikToker from Brighton, England, filmed her travel companion on a flight.

The passenger took a bag of chips and put it behind his neck against his seat.

For those who prefer a traditional neck pillow, Amazon is selling one for under $20.

The MLVOC travel pillow is a best-seller, made with memory foam.

Shoppers also get a travel kit with a 3D-contoured eye mask and earplugs.
