Most charter clients have no way to check whether they're paying a fair price. We review your flight history, benchmark it against the market, and tell you exactly where you stand.
Request your free diagnosticThe private aviation market runs on opacity. Operators set rates privately, and most quotes are produced by people who are paid more when you spend more.
The Zonda Group was built to give clients an independent read on their own numbers. We work with family offices, corporate flight departments, and HNW individuals who use private charter regularly and want a clear view of what they're actually paying for.
We start with a structured audit of recent flight history. No subscriptions, no platform access required, just a summary of flights and invoices, reviewed in confidence.
The audit is conducted without reference to any operator relationship. We are not paid by operators to recommend specific carriers, and the findings reflect what we see in your numbers, not what benefits a third party.
We compare your recent charter spend, route by route, against current market pricing drawn from operator quotes and industry data, accounting for surcharges, positioning, and aircraft category.
We request no access to internal systems or booking platforms. A summary of recent flights and invoices is enough to begin, and everything is handled in strict confidence.
"Most firms chartering regularly have no independent reference point. They rely on the same brokers who benefit from their spend."
Most engagements begin with the audit. From there, clients move into an ongoing arrangement at their own pace, if and when it makes sense.
A structured review of your recent charter activity. We benchmark each route against current market pricing and identify where spend has exceeded fair value, with a written report you can take to your finance team.
A retained relationship for clients flying regularly. Every quote from your broker is benchmarked before you accept, with a clear recommendation on whether to take it, push back, or seek alternatives. A monthly spend report tracks where the value sits over time.
For clients whose flying patterns have reached a scale where ownership, fractional, or jet card programmes may be more cost-effective than on-demand charter. We model the options and advise on structure.
Broker markup on wholesale operator cost runs to 16 per cent even among intermediaries who publish their fee, and materially higher where it is not disclosed. Our fee is set as a fraction of that, so the recovered value stays with you.
| Annual charter spend | Advisory fee | Share of spend |
|---|---|---|
| Up to GBP 750,000 | GBP 2,000 per month | 3.2% |
| GBP 750,000 to GBP 2m | GBP 3,500 per month | 2.8% |
| Above GBP 2m | GBP 5,000 per month | 2.4% |
The diagnostic establishes which tier applies. If your spend does not support a tier, we will tell you rather than place you in one.
The audit process is unobtrusive. We do not require access to internal systems, a summary of recent flights and invoices is sufficient to begin.
We speak briefly to understand your flying profile: routes, frequency, typical aircraft category, and current broker arrangement. This takes around fifteen minutes.
You share a summary of recent flights and invoices. We request no access to internal systems, and all documents are handled in strict confidence.
We source comparable pricing for each route from operator quotes and available market data. Each flight is benchmarked individually, with surcharges and positioning fees accounted for.
You receive a clear written report showing actual spend, comparable market rate, and where the gap sits, route by route. We present findings in person or by call.
All enquiries are handled in strict confidence. We respond within one business day.
