A travel guru has revealed a trick to getting yourself an entire row on a plane – and the odds are higher if you’re traveling with a friend.

Chelsea Dickenson, who shares travel tips on cheapholidayexpert.com, said the tip wasn’t fully guaranteed but was “great when it works”.

The first tip is to register as early as possible, she explains in an Instagram post.

“When choosing a seat, you’re looking for a vacant row and reserve a window seat and an aisle seat, leaving the middle seat between you,” she says.

“The theory here is that someone is much less likely to reserve a spot between two strangers and they’ll go for another row.

“And even if they reserve in the middle seat, you can ask them if they want the aisle or the window and it will work for everyone.”

The rear of the plane works best because it’s a less favorable choice, Chelsea adds and suggests travelers look into booking line 13 because “a lot of people tend to think it’s unlucky.”

She tested it on her flight from the UK to Corfu in Greece via British Airways.

The guru traveled with his friend James and boarded the plane later than usual, waiting for cabin crew to confirm boarding screening was complete.

She said, “We screwed him up, so much space!”

His advice left viewers divided as some said it was good advice for taking long-haul flights while others said it was a selfish act.

One said: “I did this last week for an overnight flight to Dubai with my seven month old baby. I had a much nicer flight! Thanks for the tip!”

“Every time I get on a plane I’m tempted to do it, and every time I cheat on it,” wrote another.

But one viewer blasted, “Knowing also how everyone will hate you, especially families. I understand why you would, but it’s also pretty selfish, isn’t it?”

Chelsea said: “Obviously this won’t work for everyone except those who do, it’s a great hack!”
