The Ministry of Defence reported that the plane was securely escorted to Stansted Airport and welcomed by police there when it landed.
In response to rumours of a security warning, RAF fighter jets were dispatched to intercept a commercial aeroplane that was “causing concern.”
Typhoon aircraft were launched to meet a Jet2 flight from Dalaman in Turkey that had been headed to Manchester.
The aircraft was safely escorted to Stansted Airport and was met by police upon landing, the Ministry of Defence said.
An RAF spokesperson said: “The RAF can confirm Quick Reaction Alert Typhoon aircraft were launched this evening from RAF Coningsby to intercept a civilian aircraft that was causing concern.”
Essex Police said: “We led a safety operation during which a Jet2.com flight from Dalaman to Manchester was diverted to London Stansted Airport this evening, Wednesday 12 October.
“Shortly before 9 pm, we received a report of a potential threat on board the flight. It was escorted to Stansted Airport, where it landed safely and was parked away from the main passenger terminal.
“The runway was closed for a short time while inquiries were carried out.”

Police said they were then able to establish there was no threat on board.
In a statement, Jet2 said: “The aircraft landed safely and taxied to a remote stand, and customers have now disembarked.
“Our teams are working very hard to look after customers, and we would like to apologise to everyone onboard for any inconvenience or upset caused by this unforeseen incident.
“We understand that the authorities were alerted to a potential security threat, however, this has been downgraded and the incident has been declared as over.”
