A transatlantic trip on KLM Royal Dutch Airlines took an unexpected detour after a rat was discovered roaming freely inside the cabin of a Boeing 777 en route to Aruba, disrupting travel plans for hundreds of passengers and grounding the aircraft.
The rodent was first spotted while the flight was already over the ocean. Video later published by Dutch outlet De Telegraaf showed the rat moving along the cabin’s curtain rails, at times disappearing into overhead storage areas.
The roving rodent also jumped between passenger compartments used for carry-on luggage.
KLM confirmed the incident, calling it “a very exceptional” situation. A spokesperson told Dutch media that the rat was discovered mid-flight and that while the circumstances were “very unfortunate for the passengers,” cabin crew managed the situation carefully.
“The passengers remained calm, and the staff kept a close eye on the animal,” the airline said, noting that it did not come into contact with onboard food.
Flights between Amsterdam and Aruba typically last around 10 hours, and while the outbound journey continued, the real disruption came afterward.
The return flight scheduled for December 10 from Aruba to Amsterdam, with a stop in Bonaire, was canceled so the aircraft could undergo a deep cleaning before being cleared for service again.
KLM described the experience for travelers as “frustrating and unpleasant,” adding that passenger safety and well-being were its top priorities.
Affected travelers were provided overnight accommodations while the airline worked to rebook passengers on alternative flights.
While rare, the KLM incident is not the only time an unexpected animal guest has caused turbulence for airlines. In October 2024, passengers on a Spirit Airlines flight from Dallas to Los Angeles spotted what social media users dubbed a “super rat” trapped inside a cabin light panel, its movement visible through the glass during the flight.
Spirit later acknowledged the video and said it was taking steps to address the situation.
Other animal-related mishaps have also grounded planes, including a European flight delayed for days after more than 100 hamsters escaped their cages, and a separate U.S. flight diverted after a mouse reportedly emerged from a passenger’s in-flight meal.
