Operator or broker, Part 135 or not, and the empty legs that eat the margin.
A broker arranges flights on other operators' aircraft and needs no certificate, only DOT's broker disclosures; an operator holds an FAA Part 135 certificate and carries operational control, the pilots, the maintenance program and the liability. Most people start as brokers, or manage an owner's aircraft on someone else's certificate.
Every one-way trip has a leg home. Pricing that covers the empty leg, selling it as an empty leg, or finding a return passenger is what separates a profitable trip from a busy one.
Operators grow by managing owners' aircraft and chartering them when the owner isn't flying; brokers grow by turning one-off flyers into jet-card or block-hour clients who pay in advance.
A focused fleet, one type with one maintenance program and interchangeable crews, keeps costs predictable. Summer and the holidays are the peaks; the quiet months need corporate shuttles or block contracts.
| Revenue stream | Pays | Scales |
|---|---|---|
| On-demand charter The core. Price by flight hour, plus repositioning, fees and taxes. | High per hour | Medium |
| Jet cards & block hours Clients buy hours in advance at fixed rates. Cash up front; the commitment is yours. | Prepaid | Good |
| Aircraft management Running an owner's aircraft: crews, maintenance, hangar. Recurring, and it brings aircraft to charter. | Monthly fee | Good |
| Empty legs Selling the repositioning flight at a discount. Recovers cost that would otherwise be lost. | Discounted | Medium |
| Catering & ground Billed through at a markup. Small on one trip, steady across them. | Small, high margin | Good |
| International trips Permits, customs and longer crew duty. More work, more margin. | Highest per trip | Medium |
Selling seats or flights on an aircraft not operated under an FAA Part 135 (or Part 121) certificate is illegal charter, and the FAA pursues it; anyone selling or buying a flight should confirm the operator's certificate and insurance. Air charter brokers must follow DOT's rules in 14 CFR Part 295: say plainly that they are brokers, name the operator, and disclose their own insurance. Federal excise tax and segment fees apply to most domestic charter, international flights carry their own taxes and fees, and crew duty, maintenance and drug-testing rules come with the certificate. Aircraft insurance and financing are specialist work. This is general information, not legal or tax advice.
