A British woman who tried to open the door of a plane mid-flight was sentenced to two years in jail.

Chloe Haines, 26, was on a flight from London Stansted Airport to Dalaman in Turkey in June 2019 when crew members and fellow passengers had to stop her from opening the door.

"Ms Haines' behaviour was one of the most serious cases of disruptive passenger behaviour that we have experienced, and we have banned her from flying with us for life," said Steve Heapy, CEO of Jet2.com and Jet2holidays in a statement.

Two Royal Air Force fighter jets were scrambled to escort the jet back to Stansted Airport following the incident, reports CNN.

Jet2 billed Haines, from High Wycombe, west of London, more than £85,000 ($110,000) after her "extremely disruptive behavior" caused the flight to be diverted.

Chelmsford Crown Court heard how Haines had mixed alcohol and medication before the incident, which she didn't really remember, the UK's PA Media news agency reports.

Prosecutor Michael Crimp told the court how Haines "lunged" to open the door of the plane, which was carrying 206 passengers. Haines had earlier pleaded guilty to endangering the safety of an aircraft and assaulting Jet2 crew member Charley Coombe.

"Those that are trapped in the confined space of the aircraft will inevitably be distressed, frightened and petrified by the actions of those who in a drunken state endanger their lives," Judge Charles Gratwicke said during sentencing, according to PA.

"For some it will be their worst nightmare come true."
