Trusted in the skies since 2008.
Built in Portugal. Operating worldwide.
Based in Ericeira, Portugal, Primeslot started in September of 2008 and entered the aviation market in January of 2009. Through the years, we have gained the trust of the industry.
Over the years, our team built something rare in aviation: genuine multi-discipline expertise. From flight dispatch and ground coordination to permits, security and brokerage — every professional at Primeslot understands the full picture. That breadth is what makes us a different kind of partner.

Precision
A consistent internal method designed to eliminate operational ambiguity.
Partnership
We become an extension of your team — quietly, reliably, around the clock.
Meet our founder.
"I started in this industry with nothing but passion and a determination to prove that operations done right make all the difference. Everything I've built since then has been in service of that same belief."
I have been driven by a passion for aviation since I started my career at just 19 years old. At 21, I formalised and deepened my technical knowledge at a renowned Aviation School in Portugal, graduating as a Flight Operations Officer.
At 28, as a woman entering a traditionally male-dominated industry, I founded Primeslot Aviation Support — not with the backing of a large corporation, but with deep operational knowledge, an uncompromising work ethic, and a clear vision: to build the partner that operators actually needed.
What started as a bold personal milestone has grown into a globally trusted brand, built on transparency, precision and the kind of commitment that only comes from someone who has lived every aspect of this operation.
The industry's trust is not given — it is earned, every single day. And that is exactly how we intend to keep it.
"There are only a few people in a dynamic sector such as aviation where you can blindly trust someone to stand and deliver every time with perfection. Sandra Cardoso is one such person. She takes on all challenges with a calm mind and always comes up with the best possible solutions. What I admire the most is that she brings a touch of humanity to her profession — a very rare quality in today's world."
