How to Estimate Business Jet Trip Costs Accurately

Accurate trip cost estimation is the foundation of charter pricing and owner cost management. Here's a breakdown of every cost element to consider.

Fuel

Fuel is typically the largest variable cost. It depends on block time, fuel burn rate, and local fuel prices. Always use actual fuel price data from the destination FBO — prices vary significantly between airports and can change daily.

Handling & FBO Fees

Ground handling fees include ramp, GPU, potable water, lavatory service, and parking. These vary widely — a major hub can charge 10× more than a regional airport. Always request a handling quote in advance.

Navigation Charges

EUROCONTROL charges apply to all IFR flights in European airspace, calculated by distance and aircraft weight. Additional charges apply in some non-European airspace regions including the US RNAV/RVSM areas.

Landing & Overflight Fees

Most airports charge landing fees based on MTOW. Some also charge noise surcharges and passenger facility charges. International overflights require route facility charges paid to each country's ANSP.

Crew Expenses

For multi-day trips, factor in crew hotel, per diem, and transport. Per diem rates vary by country — Prometheus One uses IATA standard rates as defaults, configurable per operator.

Fixed Cost Allocation

Don't forget to allocate a portion of fixed costs (maintenance, insurance, crew salaries) to each flight hour. This is essential for true cost-of-ownership analysis and charter pricing.

Using Prometheus One for Estimates

Prometheus One pulls live fuel prices, applies EUROCONTROL and ANSP charges automatically, uses ForeFlight or wind-adjusted flight times for accuracy, and produces a full P&L breakdown per flight — all in under a minute.
