A young woman was stunned after finding a pair of dirty knickers on her seat after boarding a flight.

Rebecca Naish, from Buckinghamshire, England, was travelling with Virgin Atlantic when she found the pants on her seat.

“I got on the flight from London Heathrow to Vegas on Saturday,” the 36-year-old told Sun Online Travel.

“I went to sit down and there was a black pair of lacy pants on my chair — only on a flight to Vegas would you find that.

“The man next to me was horrified.

“I had to wait a while to get the flight attendant’s attention, as they were boarding people.”

It isn’t clear who the knickers belonged to, although it was most likely a previous passenger.

“(A flight attendant) finally came over, so I showed her and explained,” she said.

“She then just picked them up, barehanded, and took them away and apologised.”

Thankfully, Ms Naish found the funny side of the situation and sent the pictures of the missing pants to her colleagues on the flight.

Social media users thought it was less hilarious after Ms Naish shared the image on Twitter.

“Don’t think much of Virgin Atlantic’s new pyjama policy!” she wrote alongside the photo.

“Oh that’s so gross! — hope your flight gets better!” one woman said.

Another remarked: “At least the seat is wipe clean.”

Virgin Atlantic replied to Ms Naish on Twitter: “Hi Rebecca, I am so sorry that this was on your seat as you boarded the flight.

“Please make a member of the crew aware of this immediately.”

A spokesperson told Sun Online Travel: “We’re sorry to hear of Ms Naish’s experience on-board one of our aircraft and would like to apologise.

“We never want to disappoint our customers and will be looking into this incident as a high priority.”
