Proton Air Services

What Proton Air Services does

Proton Air Services is a privately held Greek aviation services company founded in 1989 that provides integrated ground handling and flight support services at 11 airports across Greece and Cyprus for business aviation operators, commercial airlines, charter companies, and cargo/government flights. The company is Hellenic Civil Aviation Authority (HCAA) certified and holds ISO 9001 and ISO 14001 certifications. Its service portfolio spans eight core offerings: ground handling support (ramp, passenger, baggage handling), slots and permits acquisition, refueling, subcontracted maintenance support, catering, airline representation, air charter booking, and VIP meet & greet services. Leadership is provided by CEO Konstantinos Krystallis, supported by a team of 14 direct employees plus subcontracted maintenance engineers with 20+ years of MRO experience.

The company generates revenue through a mix of professional services fees and transaction-based margins, primarily from refueling, charter arrangements, and airplane representation work. Pricing is quote-based and not publicly disclosed, varying by aircraft type, services bundled, and airport. Distribution is exclusively direct through company-owned station offices at each of the 11 airports, with no intermediaries or third-party sales channels. GTM is enterprise field sales targeting airlines, private jet operators, and charter companies requiring ground handling and flight support. The company is a member of the European Business Aviation Association (EBAA), the National Business Aviation Association (NBAA), and partners with the Greek National Tourism Organization (GNTO) and the Sky Valet FBO network (joined late 2023) to extend reach. The firm is bootstrapped, with no disclosed funding rounds, acquisitions, or external institutional investors.
