Masayoshi Son's 11-hour Pacific dash, and the corporate jets that followed

The number that stops the eye is 1,388.9 — metric tons of carbon dioxide from yesterday's 196 tracked private flights, a 24-hour burn that covered 168,931 miles over 368.5 hours. The top mover was Masayoshi Son, whose single flight consumed 11 hours 38 minutes in the air — the day's heaviest personal schedule — and produced 52.5 tonnes of CO₂, the largest individual total among tracked owners. The busiest destination by arrivals was Harry Reid International Airport in Las Vegas (KLAS), which swallowed nine landings — the usual gravitational pull for entertainment and corporate events.

The day's longest flight was also its most editorially loaded: Masayoshi Son's Gulfstream G650ER, tail N302TR, departed San Diego International Airport and flew 5,581 miles nonstop to Tokyo Haneda International Airport in 11 hours 38 minutes. The flight lands the SoftBank Group founder in Tokyo just days after the company priced its $11 billion junk bond for OpenAI, as reported by (bloomberg.com) this week. The Gulfstream G650ER, a 19-seat ultra-long-range jet, is a workhorse for Son, who has been a regular on the California-Tokyo corridor. The Haneda arrival suggests a busy schedule of meetings in the Japanese capital — though no public appearance has been tied to the flight.

Corporate aviation dominated the middle of the pack. Exxon Mobil's Bombardier Global 6000, tail N100A, flew from Adolfo Suárez Madrid–Barajas Airport to George Bush Intercontinental Airport in Houston in 9 hours 49 minutes, covering 4,996 miles

. The flight lands the oil giant's jet back in Texas after what appears to be a European swing. Volkswagen's Dassault Falcon 7X, tail D-AGBA, departed Middle Georgia Regional Airport and flew 4,782 miles to Ingolstadt Manching Airport in Germany in 8 hours 36 minutes — a return to headquarters after a week of meetings in the American South

. And Reliance Industries' Bombardier Global 6000, tail VT-PRI, flew from Vienna International Airport to LaGuardia Airport in 8 hours 27 minutes, covering 4,206 miles

. The flight lands Mukesh Ambani's jet in New York just as the Indian conglomerate's energy and retail divisions are navigating quarterly earnings season.

Lawrence Stroll's Bombardier Global 7500, tail OE-LSS, departed Austin Bergstrom International Airport and flew 4,860 miles to RAF Brize Norton in 8 hours 25 minutes yesterday

. The flight lands the Aston Martin chairman and Formula 1 team owner back in the UK just ahead of the Mexico City Grand Prix weekend, per (espn.com) this morning. Stroll has been a regular on the Austin-UK corridor during the US Grand Prix swing. Separately, Vinod Khosla's Gulfstream V, tail N85NV, flew from Seletar Airport in Singapore to Al Maktoum International Airport in Dubai in 7 hours 11 minutes, covering 3,627 miles

. The flight lands the Sun Microsystems co-founder and Khosla Ventures principal in the UAE just days after he closed the $9.612 billion purchase of the Seattle Seahawks, as the desk noted in a previous digest.

Eli Lilly's Gulfstream G650ER, tail N307EL, is currently airborne over the Atlantic after departing Indianapolis International Airport for Adolfo Suárez Madrid–Barajas Airport yesterday in 7 hours 8 minutes

. The flight lands the pharmaceutical giant's jet in Europe just as the company prepares for a key regulatory decision on its obesity drug pipeline.
