A WOMAN allegedly reached over and groped a female passenger during a packed flight.

Heidi McKinney, 26, was flying from Las Vegas to Portland, Oregon, on Sunday when she touched the woman’s breasts and genitalia without consent, police say.

Authorities were alerted to the incident by the crew on Alaska Airlines Flight 621, and once the plane landed they interviewed the alleged victim, who said the touching was not consensual.

Ms McKinney was taken into custody, where she was charged with third-degree sexual abuse and her bail was set at £1730 ($3391).

However she was released the following day, with charges dropped after a “no complaint” disposition was filed that afternoon.

US Federal officials will review the case.

GROPED DURING A TRIP

Just last month, a man was accused of sexually assaulting a sleeping woman on a flight from Dubai to the US, allegedly whispering: “I love you, you’re so pretty” and proceeding to cover her in lotion — including her breasts. She later discovered her G-string had been pushed to the side, exposing her.

That same month, a different sex assault case emerged on a plane. Chelsea Schiffel told the Daily Telegraph that she was groped by a man sitting next to her on a United Airlines flight from Los Angeles to Sydney, when she was just 15-years-old.

But upon reporting what happened to the airline, she claims she was criticised for wearing “extremely short shorts”.

Meanwhile, last year two airport security workers were fired after one confessed to using a trick scheme to allow her colleague to grope attractive passengers.

According to a police report, an unnamed rogue male worker at Denver International Airport in the US would signal to his female colleague when he spotted an attractive man. She would then trick the scanning machine’s computer by entering the wrong gender identity information, so it would detect an anomaly in the groin area and trigger an alert for a pat-down search.

Meanwhile, in 2014, an Australian woman revealed shocking details of her alleged sexually assaulted on board a Malaysia Airlines flight.

She claimed she was sitting at the back of the plane in a row that was vacant except for a traveller six seats away when she was attacked twice by the chief steward, even filming her ordeal.
