(CNN) Shortly after takeoff on an eight-hour flight from London to Washington, DC, a woman says she started receiving disturbing messages on the in-flight system.

Jessica Van Meir, 24, was traveling on Saturday for business. She told CNN she got up to use the bathroom early in the flight, and when she returned to her seat the messages started popping up on the screen.

Virgin Atlantic's in-flight entertainment system allows passengers to watch movies, TV, play games and send messages to people in other seats.
