When most people think about booking a private flight, they picture the aircraft cabin, the convenience of skipping long security lines, or the flexibility of flying on their own schedule. What often gets less attention — but matters just as much — is who is actually operating the aircraft. That's where the concept of Part 135 certification, and the vetting process behind it, comes into play.
Sky500.com is an online travel service that connects travelers with certified Part 135 charter operators for private jet flights, including discounted empty leg flights. It's important to understand what that means in practice: Studio Jet, Inc., which does business as Sky500.com, does not own, operate, maintain, or charter its own aircraft, and it is not a direct or indirect air carrier or Part 135 operator itself. Instead, Sky500 works with a network of operators who hold that certification and are responsible for the actual flights.
What Does Part 135 Certification Actually Mean?
Part 135 refers to the section of federal aviation regulations that governs on-demand air carrier operations, including most charter flights. Operators who hold this certification are subject to oversight covering areas such as pilot qualifications, aircraft maintenance programs, and operational procedures. Because charter flights operate differently than scheduled airline service, this certification framework exists specifically to address the on-demand nature of private aviation.
For travelers, the key takeaway is simple: not every aircraft or pilot combination is treated the same way under federal rules, and understanding whether an operator is properly certified is a foundational part of evaluating any charter option.
Why Operator Vetting Matters to Travelers
Private aviation involves a wide range of operators, each with their own fleets, maintenance practices, and operational histories. For a traveler trying to book a flight, it can be difficult to independently research and compare operators, especially when time is limited or the request involves a last-minute trip.
This is one of the reasons a service like Sky500 can be useful. Rather than a traveler needing to individually contact and evaluate operators, Sky500 works within a network of Part 135 certified operators, helping match travelers with options suited to their trip. Because Sky500 does not operate aircraft itself, its role is focused on the connection between traveler and operator, not on aircraft operations.
The Kinds of Questions Worth Asking
Whether you're working with a broker or reaching out to an operator directly, there are a few categories of questions that are generally worth asking before booking any charter flight:
- Certification status: Confirm that the operator flying the trip holds current Part 135 certification.
- Aircraft type: Ask what kind of aircraft will be used and whether it fits the mission — a short regional hop and a transcontinental trip often call for different categories of aircraft.
- Maintenance and crew practices: While specific maintenance records are typically managed by the operator rather than a broker, understanding the general maintenance and crew scheduling approach can be a helpful part of your due diligence.
- Communication and transparency: A reputable broker or operator should be willing to answer questions clearly and explain how a trip will be handled from booking through arrival.
These questions apply broadly across the industry, and asking them is a healthy habit for any traveler considering a charter flight, regardless of who they book through.
The Range of Aircraft in the Network
One advantage of working with a network rather than a single fleet operator is variety. Through its network of Part 135 certified operators, Sky500 can help connect travelers to a range of aircraft categories depending on trip needs — from turboprops and light jets up to larger cabin aircraft. Generally speaking, this network includes aircraft types such as the Beechcraft King Air series, Bombardier Challenger series aircraft, Airbus corporate jet variants, and larger options like the Boeing 737 BBJ, among others. The right aircraft for a given trip depends on factors like passenger count, distance, and airport requirements, and having access to a broader network can make it easier to find an appropriate match.
It's worth noting that any information about aircraft availability for a specific trip should come directly from the operator handling that flight, since availability and specific aircraft configurations can vary.
How Sky500 Fits Into the Picture
Sky500's role is to serve as a connector — helping travelers identify and reach certified Part 135 operators without the traveler needing to independently research every option in the market. There is no membership fee to use Sky500, which means travelers can explore options, including discounted empty leg flights, without an upfront cost simply to inquire.
Because Sky500 is not itself an air carrier, questions about a specific flight's crew, maintenance history, or operational details are ultimately answered by the certificated operator conducting that flight. Sky500's function is to help facilitate that connection and support the booking process.
Final Thoughts
Understanding the role Part 135 certification plays — and knowing the difference between a booking service and an actual air carrier — helps travelers make more informed decisions about private aviation. Sky500.com aims to simplify the process of connecting with certified operators across a range of aircraft types, while leaving the operational responsibilities where they belong: with the certificated Part 135 operators themselves.
