Amsterdam, June 20, 2026, 20:01 CEST
- KLM flight KL791 turned back to Amsterdam Schiphol after the crew declared an emergency while en route to São Paulo. The Boeing 777-300ER landed safely, according to aviation sources.
- The outage affected more than a single plane as the Schiphol board had the flight shown under KLM, Air France, GOL, and SAS codes.
- KLM and airport officials haven’t confirmed the cause. Reports mentioning an oil issue are still unverified.
KLM flight KL791, a Boeing 777-300ER headed for São Paulo, turned back to Amsterdam Schiphol soon after takeoff and declared an emergency. The plane, PH-BVS, landed safely and taxied to the gate on its own, according to aviation reports.
KLM’s problem flight wasn’t a short hop. The June 19 service to São Paulo is a long-haul route, Schiphol data shows. It also carried Air France, GOL and SAS codeshare numbers, so delays would hit travelers booked not just with KLM, but its partner airlines too.
Disruption looked limited by Saturday. Schiphol’s board showed the June 20 KL791 flight as departed. Actual departure was 13:18 local, behind the planned 13:00.
Flight-tracking data shows the June 19 flight left Amsterdam at 11:32 UTC, then diverted back. The same plane, PH-BVS, later took off for São Paulo at 15:57 UTC and landed at 03:04 UTC. That suggests a delay instead of the route being suspended.
KLM flight KL791 left Amsterdam at 13:20 CEST, Airlive reported, but reversed course over the English Channel after declaring an emergency. According to Aviation24.be, the crew put out a 7700 squawk, the general emergency code, once the plane was at around 31,000 feet near the Channel Islands.
Airlive said plane spotters saw the aircraft dump fuel as it headed back to Schiphol, a move jets sometimes make to drop weight before landing. The jet landed on runway 27 and then went to gate F3, according to the same report.
Uncertainty still surrounds the fault. The Aviation Hub pointed to aviation-monitoring reports mentioning a possible oil leak, but Aviation24.be noted there is no official word on the exact cause. That’s important: suspicion of a technical problem isn’t confirmation of a defect.
KLM lists its Boeing 777-300ER as a long-range, twin-engine plane with a 12,000 km max range and seats for up to 381, but did not say how many people were on KL791. The Aviation Hub, using Planespotters data, reported PH-BVS was delivered to KLM in February 2017 and is one of 16 777-300ERs flying for the airline.
Based on what’s out now, this is an operations issue, not a wider move across the fleet. The plane was flown back to KLM’s main base for easier maintenance and handling, instead of staying at an outstation. Schedules showed the route running again the next day.
The Brazil connection carries more weight in the competition. Reuters said in April that Air France-KLM and Lufthansa put in bids for a minority stake in TAP, with TAP’s appeal tied in part to its Lisbon routes to Brazil, Africa and the US. Performance on Europe–Brazil long-haul routes feeds into the race for transfer and premium customers, even when a single event is minor in dollar terms.
Air France-KLM shares were shut on Saturday. The airline’s Paris-listed stock had ended at 12.46 euros Friday, off 0.99%, according to Yahoo Finance data.
KLM’s next move depends on what turns up in the inspection. If it’s a minor fault, this stays a delay and nothing more; if it’s an engine, oil, or another major technical issue, the plane could be out longer, adding strain on KLM’s long-haul operations, which already run tight. Right now, KL791 declared an emergency and landed back at Schiphol. The cause is still unconfirmed.
