Lufthansa flight diverted to Lyon after power bank catches fire

A routine European passenger service turned into an emergency on Saturday, 26 September 2026, when a portable charging device ignited mid-flight, forcing an unexpected diversion to France. Lufthansa flight LH1170 had departed from Frankfurt/Main on 26 September 2026, bound for Lisbon in Portugal. Specifically, the Airbus A321-200 aircraft, registered as D-AISB, carried 198 passengers and six crew members, according to airline and aviation records.

Flight data shows the service departed Frankfurt more than an hour late before cruising at altitude. While flying roughly 70 nautical miles northeast of Lyon, a passenger's power bank overheated in the seat area and caught fire. Swift action by the flight attendants saw the device placed inside a dedicated containment pouch. Lufthansa confirmed that the cabin crew immediately secured the device in a special bag for the safe storage of lithium batteries, known as a Lithium Safe Bag, which is designed to isolate overheating cells and stop flames from spreading.

Pilots declared an emergency to secure landing priority, ensuring the jet could descend swiftly without obstruction. Continuing onward to Lisbon would have meant nearly two more hours in the air with a damaged battery on board, prompting the crew to choose Lyon as a precautionary stop. The Airbus A321 landed safely on runway 17L at Lyon Saint Exupéry Airport. Ground teams reported no injuries among any of the occupants on board.

The unexpected stop left travelers stranded abroad overnight. The carrier arranged hotel lodgings for everyone on board before getting them onto alternative connections the following day, 27 September 2026, to complete their journeys to Lisbon. Meanwhile, the aircraft involved remained on the ground in Lyon for maintenance checks before positioning back to its home hub in Frankfurt empty, giving the airline access to engineering support.

The weekend proved particularly taxing for the German flag carrier. Alongside the Lyon diversion, a separate departure bound for North America was forced to turn back over Scotland and land in Manchester due to an unusual cabin smell. That separate flight from Frankfurt to Toronto carried a larger load of travelers.

The incidents highlight ongoing industry concerns regarding portable energy storage. Power banks store a large amount of energy in a compact space, and damaged or faulty units can enter thermal runaway with little warning. Rules enforced across the airline group prohibit charging devices from being plugged into aircraft power outlets or used while airborne, with exceptions made only for approved medical devices. Travelers remain restricted to carrying a maximum of two units in their hand luggage. They must keep them either on their person, inside seat pockets, or tucked into carry-on luggage beneath seats rather than in overhead bins, and units exceeding a specific capacity must be declared in advance.
