Jan Koum's Gulfstream G650ER N143 crosses from LaGuardia to Paris-Le Bourget in six hours

Jan Koum's Gulfstream G650ER, tail number N143, departed LaGuardia Airport in New York at 17:58 UTC on Sunday, October 18, 2026, and landed at Paris-Le Bourget International Airport six hours later at 23:58 UTC. The flight covered a great-circle distance of 3,143 nautical miles, or 3,617 miles, at an average ground speed of 523 knots. The aircraft reached a highest altitude of 43,025 feet and a top ground speed of 640 knots.

The Gulfstream G650ER is an ultra-long-range jet with a range of 7,500 nautical miles, a top speed of Mach 0.925, and a ceiling of 51,000 feet. It typically seats 12 passengers and up to 19. Our estimate for this flight: about 2,822 US gallons of fuel burned and about 27,111 kilograms of CO2 emitted, roughly the same as driving a car 67,107 miles. The aircraft used 42 percent of its maximum range on this leg.

The aircraft spent 6 hours in the air on this leg. It departed from LaGuardia Airport, which has a longest runway of 7,002 feet at an elevation of 21 feet. It landed at Paris-Le Bourget International Airport, where the longest runway is 9,843 feet at an elevation of 218 feet. The distance from the owner's home base at Teterboro Airport to Paris-Le Bourget is 3,150 nautical miles.

This was the third landing by one of Jan Koum's Gulfstream G650ERs at Paris-Le Bourget in the tracked window from May 8 to October 18, 2026. The previous landing at the same airport occurred on September 29, 2026, 19 days before this flight, by N158, another G650ER in the fleet. Jan Koum's home base is Teterboro Airport in New Jersey, and his most common destinations in the tracked window were Teterboro, Hartford, and San Jose. Before this transatlantic leg, N143 had flown from Hartford to Teterboro on October 18, a 34-minute hop of 90 nautical miles.

In the 30 days before this flight, the owner's three Gulfstream G650ERs flew 16 flights totaling 44.2 hours in the air. Those flights covered about 19,446 nautical miles and used 11 airports in 3 countries. The longest leg in that period was a 5,027-nautical-mile flight from Nuremberg to San Jose on October 3, 2026, flown by N158.

Jan Koum is the co-founder and former CEO of WhatsApp, a technology investor with a net worth estimated at $16.9 to $17 billion. He arrived in the United States at age 16, worked as a grocery-store cleaner, built WhatsApp to 450 million users, and sold the company to Facebook for roughly $19 to $22 billion in 2014. He left Facebook and WhatsApp in 2018 over data privacy and monetization disputes. Jan Koum owns a fleet of three Gulfstream G650ERs, all held by TVPX Aircraft Solutions Inc as trustee, an anonymizing structure that keeps the beneficial owner off the FAA registry.

The owner's fleet includes the superyacht Moonrise, a 100-meter motor yacht built by Feadship in 2020. As of a fix logged 25 minutes ago, Moonrise was at rest in the West Mediterranean, 360 nautical miles from the arrival airport.

If Jan Koum was aboard, the flight would continue a pattern of transatlantic travel between the United States and Europe.
