Sandra Corinna Kinzi spent $5.5 million turning her Gulfstream G450 into a flying reflection of her personal style, and the private jet is unlike anything else.
While most jet owners might settle for some new upholstery or tech upgrades, the CEO of SCK Aviation had different ideas.
She went all-in with a bold, all-black redesign that’s part luxury, part statement piece.
From custom marble countertops to matte finishes, every inch of the Gulfstream G450 screams ‘one of a kind’.

Let’s start on the outside.
Sandra Corinna Kinzi had the entire airplane painted in matte black, which is a dramatic move that reportedly cost around $500,000.

Inside, the makeover continues with fabric seating, sleek black marble from Italy in the galley and bathroom, and a custom-designed carpet in a black-and-grey pattern.
To break up the monochrome just a bit, she added chrome accents on light fixtures and seatbelt buckles.

It’s dark, stylish, and surprisingly cozy.
And it’s not just a personal passion project.
After all, Kinzi’s flying fashion statement won her the 2024 Yacht & Aviation Award for interior design.
The award recognizes standout luxury in air and sea travel, and Kinzi’s vision clearly stood out from the usual beige-and-glossy wood interiors
Of course, looks aren’t everything, especially in aviation.
While the Gulfstream G450 provides a luxurious flying experience, it is no slouch when it comes to performance.
With a range of nearly 5,000 miles, this private jet is perfect for Kinzi’s frequent international trips between Austria, the Netherlands, and the US.
And let’s face it: if you’re going to fly that far, you might as well do it in a jet that feels like your living room at 41,000 feet.
If you can’t quite afford a private jet, perhaps the best alternative is to fly an airline that gives you a private suite in First Class.
Or like us, you might just have to watch others doing it.
