Why It MattersCorporate and executive flying clusters around a few operators and Northeast US airports, so emissions and traffic concentrate in a small group of fleets and gateways.
Tracked private-jet activity for October 27, 2026 (UTC) totaled 241 flights, covering 191,284 miles over 420 hours and producing 1,619.1 tonnes of carbon dioxide. Marathon Petroleum's fleet logged the heaviest corporate schedule, with 14 flights totaling 22 hours 55 minutes, and was also the largest single emitter, at 72.7 metric tons of CO2. Teterboro Airport (KTEB) was the busiest destination by arrivals, with eight landings.
Joseph Tsai, Alibaba co-founder and Brooklyn Nets owner, flew his Global 7500 (VP-COR) from White Plains (HPN) to Tokyo Haneda (HND). The aircraft is a 19-seat ultra-long-range jet with a top speed of Mach 0.925. Tsai has logged 18 flights in the past 30 days, with Republic as his most common stop. The arrival followed a short repositioning hop from Newark earlier in the week, and no public appearance has been tied to the trip.
