Delta Air Lines Flight DL81 from Paris-Charles de Gaulle to Seattle was diverted to London Heathrow, then rerouted via New York JFK before completing the journey to Seattle on an Airbus A330-900 carrying 209 passengers. The long-haul service, scheduled as a nonstop transatlantic flight, turned into a multi-stop disruption after a mechanical issue involving an onboard lavatory prompted the initial diversion.
The Heathrow stop was used to investigate and troubleshoot the problem, while the onward routing through New York was driven by crew duty-time limits before the aircraft could continue to the US West Coast. The aircraft reached Seattle roughly nine to 11 hours later than planned, depending on the source, after an itinerary that combined an equipment fault with operational constraints on a heavily booked international sector. The case stands out as an irregular-operations example on a major Delta transatlantic route, with the disruption confirmed through matching flight details across multiple aviation and business reports.
