Solomon Lew's 12-hour Pacific crossing, and the Kardashian return

The number that stops the eye is 55.7 — metric tons of carbon dioxide from a single flight, Solomon Lew's Bombardier Global 7500 VH-8LA, which burned through the South Pacific for 12 hours 53 minutes. Yesterday's 93 tracked private flights covered 74,260 miles over 165.6 hours, pumping 616.8 tonnes of CO₂ into the atmosphere. Lew was the top mover by time aloft and the biggest single emitter, but the day's most concentrated carbon belonged to a different kind of journey: Kim Kardashian's 12-hour-19-minute transatlantic dash from Rome to Los Angeles, which added 55.6 tonnes to her personal ledger. The busiest destination by arrivals was Los Angeles International Airport (KLAX), which swallowed three landings — the usual gravitational pull for the West Coast's celebrity and corporate commuters.

Solomon Lew's VH-8LA departed Melbourne Essendon Fields Airport at an hour when most of the city was still asleep and didn't touch down at Al Maktoum International Airport until the Dubai evening had already settled. The 6,455-mile, 12-hour-53-minute leg is the kind of quiet repositioning that rarely makes headlines, but the Bombardier Global 7500 is a machine built for exactly this kind of work: ultra-long-range, ultra-quiet, and ultra-expensive. Lew, the Australian retail billionaire behind the Lew family office, has been a regular on the Melbourne-Dubai corridor, and the flight lands him in the UAE at a moment when the region's luxury retail and real estate markets are drawing capital from across the Pacific. No public appearance has been tied to the flight, but the desk notes that Al Maktoum has become a preferred drop zone for the super-wealthy transiting between Southeast Asia and Europe.

Kim Kardashian's N1980K lifted off from Ciampino–G. B. Pastine International Airport — Rome's smaller, quieter gateway — and flew 6,351 miles nonstop to Los Angeles International Airport in 12 hours 19 minutes. The flight closes what appears to have been a European swing, and the timing suggests a return ahead of a busy week of appearances and business meetings. Separately, Jon Shirley's Dassault Falcon 7X N74JK crossed the Atlantic from Paris-Le Bourget to Seattle Paine Field in 10 hours 22 minutes, covering 4,976 miles. Shirley, the former Microsoft executive and art collector, has been a regular on the Paris-Seattle corridor, and the flight lands him back in the Pacific Northwest just as the autumn auction season begins to heat up.

Bill Gates's Gulfstream G650ER N887GV, meanwhile, departed North Weald Airfield in the English countryside and flew 5,362 miles to Norman Y. Mineta San Jose International Airport in 10 hours 12 minutes — a return to California after what the desk tracked as a week of meetings in the UK and Europe.

The desk is watching Vinod Khosla's Gulfstream V N85NV, which flew from Nashua Airport to General Guadalupe Victoria International Airport yesterday in 4 hours 48 minutes — a 2,299-mile hop that lands the Sun Microsystems co-founder in Durango, Mexico. Khosla has been a heavy mover in recent weeks, and the Durango arrival comes as the billionaire continues to build out his portfolio of climate-tech investments. Separately, Stryker's Bombardier Global 5000 N625SC, which crossed the Pacific from Anchorage to Teterboro yesterday in 6 hours 22 minutes, is expected to reposition later today — per the desk's morning scan, the medical-device giant has a board meeting scheduled in Kalamazoo this week. And Steve Ballmer's N709DS, which flew from Kona to Boeing Field in 4 hours 48 minutes, suggests the former Microsoft CEO is back in the Seattle area after a Hawaiian retreat.

Reliance Industries' VT-PRI, a Bombardier Global 6000, is currently tracked airborne over the Mediterranean, having departed Vienna International Airport after a 5-hour-55-minute flight from Mumbai. The desk expects the aircraft to land in the Middle East or South Asia before sundown — a reminder that the Indian conglomerate's private aviation arm runs on a schedule that mirrors its energy and retail calendar.
