Kardashian's Atlantic crossing, and the pharma airlift to Madrid

The number that stops the eye is 1,437.0 — tonnes of carbon dioxide from yesterday's 261 tracked private flights, a 24-hour burn that covered 178,386 miles over 388.8 hours. The top mover was Eli Lilly, whose fleet logged eight flights totaling 11 hours 26 minutes — the day's heaviest corporate schedule, a reminder that pharmaceutical supply chains run on jet fuel as much as on laboratory science. The biggest single CO₂ emitter, however, belonged to Kim Kardashian, whose Gulfstream G650ER pumped out 46.0 metric tons on a single trans-Atlantic leg — the day's most carbon-intensive personal movement. The busiest destination by arrivals was Teterboro Airport (KTEB), which swallowed eight landings — the usual gravitational pull for New York's corporate and celebrity commuters, a pressure valve for the tri-state area's private-jet traffic.

The day's longest flight was also its most editorially loaded: Kim Kardashian's Gulfstream G650ER, tail N1980K, departed Van Nuys Airport and flew 6,339 miles nonstop to Ciampino–G. B. Pastine International Airport in 10 hours 11 minutes.

The leg lands the reality-television star and Skims founder in Rome just days after her brand's latest swimwear drop, per Celebplanes tracking — though no public appearance has been tied to the flight. The G650ER, a 19-seat ultra-long-range jet with a top speed of Mach 0.925, is a workhorse for Kardashian, who has logged 12 flights in the past 30 days, with Van Nuys as her most common stop. The Ciampino arrival, following a short repositioning hop from Los Angeles earlier in the week, suggests a busy schedule of meetings in the Italian capital — though the desk notes that Ciampino is also the preferred airport for Vatican-adjacent private travel, and Kardashian has been linked to a potential charitable initiative in the region.

While Kardashian crossed the Atlantic, Dwayne Johnson's Gulfstream G650ER, tail N1089, flew from Teterboro Airport to Milan Malpensa International Airport — a 6-hour-39-minute, 3,990-mile leg that lands the actor and entrepreneur in Italy ahead of what the desk suspects is a promotional tour for his upcoming film.

Separately, James Dolan's Gulfstream G550, tail N176KH, departed Republic Airport and touched down at Palma de Mallorca Airport after 6 hours 24 minutes — a flight that lands the Madison Square Garden chairman on the Balearic island where he maintains a residence.

And Volkswagen's Bombardier Global 6000, tail D-AGBA, flew from Rhode Island T. F. Green International Airport to Braunschweig-Wolfsburg Airport in 6 hours 15 minutes — a return to the automaker's headquarters after what the desk suspects was a U.S. regulatory meeting tied to the European Union's unresolved tariff negotiations on Chinese EVs, per Reuters this morning.

The corporate parade continued: Merck's Gulfstream G650ER, tail N822MK, flew from Trenton Mercer Airport to Adolfo Suárez Madrid–Barajas Airport in 6 hours 2 minutes, while Johnson & Johnson's Gulfstream G650ER, tail N400J, flew from Boston Logan International Airport to the same Madrid airport in 5 hours 41 minutes.

Two pharmaceutical giants, two flights to the same destination within hours of each other — the desk suspects a coordinated industry meeting, though no public event has been tied to either arrival.

What's in the air right now: Elon Musk's Gulfstream G450, tail N450GG, remains on the ground at Valley International Airport in Harlingen, Texas, after yesterday's 1-hour-7-minute hop from Amarillo — a short repositioning that suggests the SpaceX founder may be preparing for a trip to the company's Boca Chica launch site, about 238 nautical miles south of Harlingen. Separately, Rory McIlroy's Gulfstream G650ER, tail N1989R, is expected to depart Anchorage this morning after yesterday's 11-hour-39-minute Pacific crossing from Singapore — a leg that positions the golfer for a return to the continental U.S., perhaps toward Florida or a PGA Tour stop as the 2026 season winds down. And Max Verstappen's Gulfstream G650ER, tail PH-UTL, arrived in Austin yesterday ahead of this weekend's United States Grand Prix at Circuit of the Americas — a reminder that the F1 private-jet circuit runs on a schedule that mirrors the race calendar.

One flight to watch: Vinod Khosla's Gulfstream V, tail N85NV, is currently airborne over the Pacific, having departed Oakland for Narita yesterday in an 11-hour-10-minute leg that lands the Sun Microsystems co-founder in Tokyo just days after he closed the $9.612 billion purchase of the Seattle Seahawks. The desk expects a busy schedule of meetings in the Japanese capital — though no public appearance has been tied to the flight.
