The Diamond DA42 Twin Star represents a leap forward in the world of light twin-engine aircraft, offering four seats, advanced avionics, and impressive fuel efficiency for private pilots and business travelers alike. Originally introduced in the early 2000s, the DA42 quickly earned a reputation for its sleek composite airframe, responsive handling, and robust safety features.
Perfect for those who require economical, efficient personal or business air travel, the DA42 delivers a premium flying experience with modern amenities and a focus on passenger comfort. This profile highlights its key features, performance metrics, cabin layout, typical charter pricing, and addresses the most common questions from discerning flyers considering this aircraft for their next journey.

The DA42 Twin Star is in the piston-twin class, making it a favorite among pilots seeking the blend of twin-engine reliability with modern technology. The aircraft seats up to four passengers and is renowned for its spacious and ergonomic cockpit, which features state-of-the-art Garmin avionics and intuitive controls. Its composite construction ensures both strength and lightness, supporting a maximum cruise altitude well beyond typical single-engine alternatives.
Efficiency is at the heart of the DA42's appeal. Its Austro AE300 diesel engines provide exceptional fuel economy, burning as little as five gallons per hour per side, while delivering quiet, smooth power and reduced emissions. For operators, the DA42's low direct operating costs and minimal maintenance requirements make it a compelling choice for both personal use and flight training organizations worldwide.
Charter clients value the DA42 for its reliability, safety record, and ability to access smaller airports and private airfields that are often unavailable to jets or turboprops. The result is a nimble, versatile flying experience tailored to shorter regional trips, with the comfort and peace of mind that only a modern twin can provide.

The figures below summarize the performance and dimensions that matter most when you are matching an aircraft to a trip. They reflect typical configurations; exact numbers vary with weight, weather, and how a given aircraft is equipped.

With a maximum range of approximately 1,051 nautical miles, the DA42 Twin Star is ideally suited for regional journeys and cross-country hops without refueling. It can connect pairs such as Los Angeles to Denver, Toronto to New York, or Paris to Rome with ease and reserves to spare. | The aircraft’s 180-knot high-speed cruise allows for efficient flight times, while its 18,000-foot service ceiling lets pilots rise above most weather and turbulence for a smooth ride. The DA42’s efficient engines and low fuel consumption give it access to a wide variety of fields, including smaller airstrips that are out of reach for larger aircraft. | For most travelers, this means flexible, direct routing and the ability to reach unique destinations quickly—offering time savings and convenience that commercial options cannot match.

The DA42’s cabin is designed for comfort and visibility, with ample headroom and large panoramic windows that fill the interior with natural light. Seating is arranged for up to four, offering leather upholstery, adjustable seats, and quiet ride quality thanks to its composite construction and advanced engine design. | Passengers benefit from a climate-controlled environment, folding tables, and in-flight connectivity options on select aircraft. The cockpit is equipped with the latest Garmin G1000 NXi avionics suite, providing pilots and passengers alike with advanced situational awareness and a modern, intuitive interface. | Baggage space totals around 57 cubic feet—more than enough for several suitcases, golf clubs, or weekend gear. For business or pleasure, the DA42 transforms short-haul travel into an enjoyable, productive experience.


Chartering a Diamond DA42 Twin Star typically runs in the range of $1200 to $1800 per flight hour, though the figure you are quoted depends on several factors. Rates move with the route, the season, repositioning (or ferry) time, airport fees, crew costs, and how a specific aircraft is equipped. Peak travel periods and one-way trips that leave an aircraft far from its base tend to sit at the higher end, while round trips and flights that align with an operator's existing schedule can come in lower.

It also helps to understand how charter pricing is structured. Most quotes are built around occupied flight hours plus those repositioning costs, landing and handling fees, taxes, and crew expenses. Because Jettly is a charter marketplace rather than an aircraft operator, you can compare live quotes from multiple FAA Part 135 and book the option that fits your route and budget.

Empty-leg flights, the discounted repositioning trips that operators are keen to fill, can also bring the cost of a Diamond DA42 Twin Star down significantly when the timing works in your favor. For an exact, current price on your specific trip, request a quote, and you will see real availability rather than an estimate.
The Diamond DA42 Twin Star fits a wide set of missions, which is part of why it stays busy. It is a strong match for:
While not intended for transcontinental or transoceanic routes, the DA42 excels for quick regional trips, pilot training, or short business missions where cost efficiency and flexibility are paramount. For groups of up to four seeking a nimble, modern aircraft with proven safety and comfort, the Twin Star is an outstanding value.

The Diamond DA42 Twin Star debuted in 2004 as the world’s first diesel-powered twin-engine aircraft, setting new benchmarks in efficiency and safety for its class.

Over the years, the DA42 has undergone continuous improvements, including upgraded avionics, enhanced comfort features, and further reductions in fuel burn and emissions.
Today, the DA42 Twin Star remains a favorite for those seeking a modern, economical twin for private and professional flying, with a global support network and a proven track record of reliability and safety.
