A Virgin Atlantic flight that started in the UK and ended in Mexico resulted in one woman being banned from ever again flying on the airline.

According to reports, a female in her late twenties permitted a man she had just met to enter the bathroom.

Allegedly, flight crew opened the door to see the oral sex taking place and demanded the two get back to their seats.

The man claimed he was helping the woman because she was sick.  The flight crew rejected his story and led them back to their separate seats.

The lady, who was drunk, began yelling at her female travel companion, according to reports from other passengers.

When the plane arrived to Mexico, authorities removed her from the plane.  She was later told she is banned from the airline.
