A former flight attendant has revealed the secret codes cabin crew use to point out their most attractive passengers, as well as how to tell if they don't like you.

Speaking on Australian radio show Kyle & Jackie O, James, who was a flight attendant for seven years, said that the crew will typically pick out the best-looking passengers on a flight.

"Obviously when we are in the cabin and we are doing the drinks we can't just be like 'Oh doll check him out. You have to be subtle about it."

"Because everyone knows their seat numbers, so we’re on the cart and he’ll be like, 'I’m thinking of doing seven days in America… being 'seat 7A'.

"And I’ll be like, 'yeah, I could do seven days in America!'"

"Or like, six days in Denmark..."
