Berkshire Hathaway has credited its aviation operations with driving a sharp rise in service group revenues during the second quarter of 2025, as demand for business travel and pilot training remained robust.
The conglomerate reported that aviation services – including fractional jet operator NetJets and training provider FlightSafety International – delivered a 9.6% year-to-date revenue increase. The growth was attributed to a larger fleet in shared ownership programmes, more in-flight hours across NetJets’ offerings, and higher average rates.
These gains were partly offset by increased crew costs, along with higher maintenance, fuel, and depreciation expenses.
Overall, service group revenues climbed by $466m (8.9%) in the second quarter and $808m (7.8%) in the first half of the year, compared with 2024. Pre-tax earnings from the division rose $96m (15.2%) in the quarter and $153m (12.5%) over six months, driven not only by aviation services but also by contributions from electronics distributor TTI, leasing operations, and Charter Brokerage, which serves the petroleum and chemical sectors.
