Flightkeys

What Flightkeys does

Flightkeys is a Vienna-based private software company founded in April 2015 by aviation experts with over 30 years of experience in flight planning and optimization. The company develops FLIGHTKEYS 5D, a cloud-based flight management system that performs cost-driven, multi-dimensional trajectory optimization for commercial airlines. The platform processes gate-to-gate trajectories in a single pass using full flight dynamics simulation, probabilistic (5th-dimension) modeling of weather and traffic uncertainty, dynamic aircraft performance data, and precise overflight cost formulas. It is positioned as a clean-sheet 21st-century alternative to legacy two-step optimization systems and supports in-flight trajectory re-optimization, contrail avoidance, and standards-based integration (FIXM 4.0, FF-ICE R1, tight ATM coupling).

The company serves approximately 100 airline customers operating roughly 10,000 aircraft globally, generating 380,000 flight plans per day and 291 million lifetime trajectories. Its revenue model is enterprise SaaS subscription with quote-based pricing tailored to airline requirements, and go-to-market is executed through direct enterprise sales to airline operations centers, supplemented by annual User Group Meetings and industry events. Strategic partnerships include a contrail avoidance trial with American Airlines, Google, and Contrails.org (62% contrail formation reduction, 69% warming reduction across 2,400 transatlantic flights), an APM integration with Storkjet, and a September 2024 strategic growth investment from Insight Partners (with founders retaining majority control) intended to fund U.S. and European expansion and roadmap acceleration. The company also operates SPACEKEYS (spaceflight planning) and SKYKEYS sub-brands under the Flightkeys Group umbrella.

Broad incumbents

• Honeywell Aerospace: Provides GoDirect Flight Efficiency and other flight planning/operations software as part of its broader aerospace portfolio. Competes in flight planning but within a much larger avionics and aerospace systems franchise.
• SITA: Air transport IT specialist serving airlines, airports, and governments with a broad portfolio including network operations, flight planning, and crew management. Overlaps with Flightkeys but as a multi-product incumbent rather than a flight-planning specialist.
• Sabre: Major global travel technology company with airline operations solutions alongside its GDS business. Adjacent competitor offering broader airline IT, with overlapping flight planning and disruption management modules.
• Amadeus: Global travel technology provider offering airline IT, Altéa passenger services, and operations solutions including flight planning capabilities. Competes broadly in airline software with a much larger portfolio.
• GE Aerospace: Formerly GE Aviation; a broad aerospace incumbent with software offerings for flight operations, fuel efficiency, and predictive analytics. Overlaps with Flightkeys in aviation optimization but as part of a much wider engine and systems franchise.

Direct peers

• Navtech (Saab): Provides flight planning, navigation data, and air traffic management solutions to commercial airlines and ANSPs. Direct peer in trajectory planning with comparable probabilistic and weather-optimization capabilities.
• IBS Software: Provider of iFlight and other airline operations platforms including flight planning, crew rostering, and disruption management. Direct peer serving similar enterprise airline customers with mission-critical software.
• Lufthansa Systems: Subsidiary of Lufthansa Group providing Lido flight planning and optimization solutions used by numerous global airlines. Direct competitor with a similar SaaS-style delivery model and airline operations center focus.
• Jeppesen: A Boeing subsidiary providing flight planning, navigation, and airline operations software to commercial and business aviation globally. The dominant incumbent in airline flight planning systems and the most direct competitor to FLIGHTKEYS 5D.

Others

• Storkjet: QAR-based Aircraft Performance Monitoring (APM) provider that integrates with FLIGHTKEYS 5D. Adjacent technology partner — not a direct competitor — supplying performance data that enhances Flightkeys' optimization accuracy.
