Daniela Deed

Daniela has worked in the airport industry since 2001 when she joined as one of the handling agents.

I worked my way up the ladder over the years, making the most of the opportunities presented to me, gaining experience and knowledge across a range of positions. I have worked in very large teams but also very small teams, which came with their own challenges and dynamics.

I am extremely proud of my time as Chairperson for their official charity partner, CLIC Sargent, when I helped to raise a substantial amount of money making a difference to lives of young people living with cancer.

I joined SES Aviation in July 2022. I have learnt a lot about FBO operations since joining and I have an incredible team working for me, who make every flight very special for our clients. Every day is different which makes it very interesting and fulfilling.

I lead with compassion and honesty.
