A 
Lufthansa flight en route from Chicago to Frankfurt was forced to divert on October 25, 2025, after an unruly passenger allegedly stabbed two teenagers with a metal fork. The flight landed at 
Boston Logan International Airport, where the man was met by authorities and subsequently charged, per the US Department of Justice. Passengers were reaccommodated onto other flights, and the plane was later ferried.
The alarming incident comes amidst a general rise in air rage incidents. These incidents often have little or no motivation and not only impact the victims involved, but also the other passengers whose travel has been disrupted, and typically result in significant punishment for the aggressor. It’s not yet clear the severity of the injuries sustained by the two victims.
An Attack Onboard A Lufthansa Flight To Frankfurt
The incident occurred onboard Lufthansa flight LH431 from 
Chicago O’Hare International Airport to 
Frankfurt Airport. This service was operated by D-ABYQ, a Boeing 747-8 with a capacity of 364 passengers in a four-class configuration. The incident occurred roughly three hours into the flight in the center seating section of the economy cabin.
The alleged attacker was named as 28-year-old Praneeth Kumar Usiripalli, an Indian national in an aisle seat who had been admitted into the United States on a student visa. Shortly after the first meal service, his seatmate, a 17-year-old male, woke up to find Usiripalli standing over him. Usiripalli allegedly then used a metal fork to stab him in the shoulder area, then stabbed another 17-year-old boy in the back of the head with the same metal fork.

Cabin crew attempted to subdue Usiripalli, to which he responded by forming a gun symbol with his hand, putting it in his mouth, and pulling an imaginary trigger. He is then alleged to have turned to slap a female passenger behind him, and then attempted to slap a flight attendant.
The Aftermath Of The Incident
The severity of the injuries suffered by the two minors has not yet been confirmed. It has been confirmed, however, that the second minor who was allegedly attacked suffered a laceration to the back of his head, while the first minor was stabbed near or on his left collarbone. These are the only confirmed injuries, and none were reported for the cabin crew so far.
The aircraft diverted to Boston, where Usiripalli was arrested upon arrival. He does not currently have lawful status in the US, and he will appear in federal court for his alleged actions in Boston at a future date. Usiripalli has currently been charged in the US District Court with one count of assault with a dangerous weapon with intent to do bodily harm while traveling on an aircraft in the special aircraft jurisdiction of the US.
Due to the extensive delay incurred by the diversion, passengers were rebooked onto other Lufthansa or partner carrier flights. The aircraft, D-ABYQ, stayed overnight in Boston and was subsequently ferried back to Frankfurt, where it reentered regular service after its arrival. As such, Lufthansa, its passengers, and its crew were severely disrupted by the actions of this individual, if the events transpired as alleged.
Disturbing Rise In Air Rage Incidents
Air rage has been a long-standing issue in air travel, particularly in the US, and there’s been a notable rise after the COVID-19 pandemic. While it’s difficult to nail down a precise cause, there are several contributing factors towards these incidents, such as jet lag, travel stress, cramped conditions in economy class, and intoxication.
No matter which class you’re flying in, airliners are ultimately shared spaces, and the actions of one passenger can impact everyone onboard. Two passengers were injured, hundreds more had their travel disrupted, and the airline had to pay for the diversion, reaccommodations, and transporting its Boeing 747-8 and crew members back to Frankfurt.
For Praneeth Kumar Usiripalli, his charges come with a prison sentence of up to 10 years, along with up to three years of supervised release and a fine of up to $250,000. Additionally, Usiripalli will likely never be allowed to fly Lufthansa again.
