As the Iran war pushes jet fuel prices higher, well-heeled travelers are facing hefty surcharges to fly private, sometimes on flights booked months prior, charter brokers and aviation insiders told CNBC.

Vimana Private Jets CEO Ameerh Naran said the firm recently booked a $520,000 flight from Dubai to London on a Boeing

business jet for a client. That same trip cost the client $400,000 in 2023. The difference was entirely due to jet fuel prices — which now average about $4.65 a gallon globally — Naran said.

It’s yet another ripple in the recent disruptions to air travel.

More customers turned to private air travel during the pandemic to avoid crowds. The option remains popular and has become more important to the aviation sector as wealthier households prop up spending in travel and other sectors.
