Airline releases strict rules for flight attendant clothing including underwear in surprising memo

An airline has reminded potential employees that they should wear underwear while working.

Yes, incredibly Delta Air Lines has really felt the need to tell budding flight attendants that they must wear underpants or knickers if awarded the chance to work for them... I wonder what spurred that on?

Delta, one of the United States' biggest airlines, recently released a two-page memo outlining the strict rules that its flight attendants have to follow, and it went down to the very last detail.

The memo, titled 'Delta Air Lines Flight Attendant Hiring Appearance Requirements Acknowledgement', explained that while staff need to be 'passionate' about customer service and to help, they must also be 'groomed'.

In order to work at Delta, you'll need to keep on top of your 'personal cleanliness and hygiene', which includes keeping your facial hair 'trimmed and neatly maintained' - and if you must use aftershave or perfume, you can only apply it 'lightly'.

And eyelashes shouldn't be 'extreme' in 'length and volume'.

There must be no originality, meaning any tattoos you may have must be hidden away behind clothing - bad luck if you have a small one on your hands, neck or face.

That includes your finger nails - no neon colors, but if you must paint them they need to be the same color, and should be 'clean, neat, trimmed and, if polished, chip-free'.

But the most interesting of all is the airline's strict clothing rules.

The memo bullet pointed to criteria which hopefuls should adhere to, reading: "Proper undergarments must be worn but must not be visible.

"Clothing must be professional and fit properly. Dresses and skirts should be at or below knee length."

It continued: "Shoes should be closed toe flats, heels or sling back. Athletic type shoes are not permitted. Tie is required with button collared dress shirts for those who choose to wear the male uniform."

It's all very strict, but there's a reason Delta Air Lines brings the most revenue in compared to every other airline in the planet.

A spokesperson for the company told the Daily Mail: "In the interest of transparency and clarity for all prospective candidates we are encouraging people to ‘dress for success’ and give a great first impression as they aspire to join the flight attendant ranks."
