Powerbank Fire Forces Lufthansa Frankfurt-Lisbon Diversion

A Lufthansa flight from Frankfurt to Lisbon was forced to divert to Lyon on Saturday evening, 26 September 2026, after a passenger's powerbank caught fire near a seat. The powerbank fire triggered an emergency response in the cabin, but all 198 passengers and six crew members landed safely around 22:00 local time at Lyon-Saint Exupéry Airport, according to German media and flight tracking data.

What happened on the Lufthansa Frankfurt-Lisbon flight?

Lufthansa flight LH1170, an Airbus A321-200 with registration D-AISB, departed Frankfurt for the Portuguese capital on the evening of 26 September. While cruising at about 35,000 feet, a powerbank began to overheat and catch fire near a seat. Crew members immediately extinguished the flames and placed the device in a special lithium-battery containment bag, Lufthansa said.

Aviation trackers recorded the aircraft diverting roughly 70 nautical miles northeast of Lyon before landing safely about 25 minutes later. The airline booked hotels for the passengers overnight and rebooked them on replacement flights to Lisbon the following morning. The jet remained on the ground in Lyon for about 16 hours before a positioning flight back to Frankfurt. It remains unclear what the powerbank's owner had done with the device before it ignited. The lithium-ion battery safety debate has grown as such incidents become more frequent.

Why did the plane divert to Lyon?

Even after the fire was contained, the crew chose to land in Lyon as a precaution. A burning lithium battery can reignite or release toxic fumes, so diverting to the nearest suitable airport is standard safety practice.

How common are powerbank fires on planes?

This is the second Lufthansa diversion in a short period. Last weekend, a Frankfurt–Toronto flight landed in Manchester in the United Kingdom after an 'unpleasant odor' was reported. The Lyon incident also follows a serious KLM event about a week earlier, when a powerbank caught fire in business class over the Atlantic Ocean on a flight to Curaçao. A passenger suffered burns, and the device later turned out to belong to former KLM director Camiel Eurlings.

Airline powerbank rules compared

Rules on carrying and using powerbanks differ by airline. Here is a quick comparison based on current policies:

• KLM and Lufthansa: powerbanks may be carried in the cabin, but passengers are not allowed to use or charge them during the flight.
• Transavia (KLM subsidiary): passengers may use and charge a powerbank on board.
• General safety rule: powerbanks must never be placed in checked baggage; they must stay in hand luggage and remain visible.

Under IATA dangerous goods regulations, powerbanks over 160 watt-hours are prohibited, while devices between 100 and 160 watt-hours require airline approval. Most consumer powerbanks fall below 100 watt-hours, but damaged or non-certified units still pose a fire risk. The 2025 Air Busan battery fire in South Korea led several airlines, including Lufthansa, to tighten cabin rules for power banks. KLM said it is investigating the Curaçao incident and will use the findings to decide whether its own powerbank policy needs to be strengthened.

Impact: what this means for travelers

Passengers flying with large-capacity powerbanks should expect closer scrutiny at the gate. Airlines are increasingly reminding travelers that lithium-ion batteries can overheat if damaged, short-circuited, or exposed to pressure. The latest powerbank fire adds to a growing list of in-cabin battery incidents, prompting regulators to study new containment and labeling requirements. Travel experts recommend keeping powerbanks in a protective case, avoiding charging them in flight where banned, and reporting any device that feels unusually hot, swollen, or emits smoke immediately to cabin crew. The EU261 passenger compensation rules may apply when a flight is diverted and passengers require overnight accommodation.

FAQ: Lufthansa powerbank fire diversion

What caused the Lufthansa flight to divert to Lyon?

A passenger's powerbank caught fire near a seat on the Frankfurt–Lisbon flight, prompting the crew to land in Lyon as a safety precaution.

Were there any injuries in the powerbank fire?

No major injuries were reported. All 198 passengers and six crew members landed safely and were taken to hotels for the night.

Can I use a powerbank on a Lufthansa or KLM flight?

Both airlines ban using or charging powerbanks in flight. They may be carried in hand luggage, but not in checked baggage. Transavia currently allows use and charging.

What should I do if my powerbank overheats on a plane?

Alert a crew member immediately. Do not try to move a burning device; cabin crews carry containment bags designed for lithium-battery fires.

Is Lufthansa changing its powerbank rules?

Lufthansa has already tightened its rules, banning powerbank use and charging on board. KLM is reviewing its policy after the Curaçao incident.
