The gas-guzzling aircraft completed the four-and-a-half hour journey on Thursday, according to flight activity information published on FlightAware.
Kerry was not on board the jet, however, as he is currently in Asia on a climate tour.
The former Democratic senator and onetime presidential candidate was appointed as the U.S. Special Presidential Envoy for Climate by Joe Biden back in January.
The appointment came despite criticism that Kerry frequently uses his family’s private plane – a Gulfstream IV twin-jet.
Private jets are known to emit up to 40 times as much carbon per passenger as a regular commercial flight.
According to The New York Post, ‘flight logs indicated that his family’s private jet spent over 20 hours in the air from February of last year to January — culminating in an estimated 116 metric tons of carbon emissions’.
In comparison, the publication reports that the average car emits just 4.6 metric tons of carbon emissions in an entire year.

It’s unclear which members of Kerry’s family were on board the jet, which took off from Boston Logan Airport Thursday morning and later landed at Friedman Memorial in Sun Valley, Idaho.
Kerry is married to canned soup heiress Theresa Heinz, who owns a lavish property in nearby Ketchum, Idaho. She has a reported net worth of $750 million
Flights show the jet flew 100miles from Bedford, Massachusetts, to Martha’s Vineyard, Massachusetts on March 26.
The aircraft then allegedly flew 90 miles from Martha’s Vineyard to Boston two days later on March 28.
Meanwhile, Kerry recently hit headlines after it was revealed he flew on the private jet from the U.S. to a climate conference in Iceland in 2019.
‘If you offset your carbon – it’s the only choice for somebody like me who is traveling the world to win this battle,’ Kerry told an Icelandic journalist at the time.
‘What I’m doing, almost full time, is working to win the battle on climate change, and in the end, if I offset and contribute my life to do this, I’m not going to be put on the defensive,’ he added.
Kerry did not explain how he offsets his carbon emissions.

However, Kerry has not escaped controversy even when he flies on commercial planes.
Last month, a snap leaked to social media showing the climate czar sitting in first class on a flight from Boston to Washington, DC without a face mask on.
Face masks are mandatory on AA flights and those who are found in violation can face fines ranging from $250 for the first offense up to $1,500 for repeat offenders.
Kerry claimed he only temporarily took off the covering.
‘Let’s be clear: If I dropped my mask to one ear on a flight, it was momentary, he wrote on Twitter.
‘I wear my mask because it saves lives and stops the spread. It’s what the science tells us to do.’
He was subsequently branded a ‘hypocrite’ by conservative pundits, including Donald Trump Jr.
