United Airlines flight UA135, which declared the emergency and diverted to London, departed from Zurich at 1026 local time on May 5 and initially headed north towards the UK.
North of Paris, the aircraft briefly declared an emergency via the 7700 squawk code, indicating there was an issue onboard.
From there, the aircraft initiated a descent, changed it’s squawk code back to the normal 3046 code, and chose Heathrow as the diversion point.
By 0942 UTC, the aircraft had landed safely without further incident.
What Was The Reason for the Emergency Landing in London?

The Aviation Herald later on released information surrounding the emergency onboard United Airlines UA135 Zurich-Newark, which diverted to London Heathrow.
It is understood that a passenger in premium economy was the culprit due to their power bank starting a small fire in the cabin.
Furthermore, the rest of the flight was cancelled as a result of this fire.
It is unclear what the extent of the damage in the cabin looks like, but it is probably significant enough to cancel the rest of the flight to Newark.
As soon as we have more information pertinent to this, then we will update you accordingly.
