A new-generation flight schedule optimization system that maximizes an airline’s total network profitability by determining the best flight time and fleet type for each flight leg.

The Most Advanced Network Planning & Scheduling Tool on the Market

Key Benefits

Maximized Profitability

The system balances network profitability and operational constraints to find the best times (for both nonstop and connecting traffic) and allocates the right aircraft to each flight in the schedule.

Improved Aircraft Utilization

Planners can develop more effective schedules that increase aircraft utilization by simultaneously adding a combination of fleeting and timing changes to the schedule.

Sensitivity Analysis/Infeasibility Finder

The system detects conflicts that may cause an infeasible schedule with respect to operational constraints, while automatically correcting input rules. The system also evaluates the cost of operational constraints relative to total profitability.

Faster Schedule Generation

The system rigorously builds flight schedules that satisfy all operational constraints, so that manual efforts are minimized.

Optimize Holidays and Special Events

The system optimizes schedules for peak travel days, such as holidays and special events, while also incorporating starting and ending transition schedules.

Enhanced Strategic Planning

Planners use the system to perform a variety of strategic analyses to evaluate different fleet types or network structures.

How Does SkyMAX Work?

Advanced Optimization

SkyMAX generates flight schedules by solving a global optimization problem that tallies and evaluates millions of schedule combinations. It uses a novel solution methodology that combines mixed integer programming (MIP) and network optimization techniques to determine a near-optimal solution.

Both techniques utilize a time-space network in which each node denotes a specific location at a specific time. Each flight schedule is represented as a flow of planes in this time-space network, and our methodology optimizes the flow through this network to maximize profitability while honoring all constraints.


SkyMAX considers numerous constraints while creating a true clean-sheet flight schedule.

Network planners could enter inconsistent or over-constrained data. SkyMAX detects and reports these inconsistent data and over-constraints. It relaxes some constraints to achieve a feasible solution. Planners have control over which constraints are relaxed by the system.

Multiple Optimization Modes

SkyMAX is a multi-purpose system that can be used in several optimization modes depending on your airline’s needs.

Network planners can perform studies, develop insights on how to trade off between conflicting objective functions and generate flight schedules that are aligned with business objectives.

Clean-Sheet Mode

Generate a clean-sheet schedule, giving SkyMAX the freedom to optimize the schedule as long as all operational constraints are satisfied.

Improvement Mode

Improve the profitability of an existing flight schedule while satisfying all operational constraints.

Evaluation Mode

For each flight schedule, gnerate itineraries (passenger routes), assign passengers to them and calculate financial KPIs, including revenue, cost and profit.


All optimization modes are designed to improve:


Fix constraint violations, such as fix turn and fix gate, to improve schedule operability.

On-Time Performance

Improve schedule robustness.


Generate itineraries that maximize passenger connectivity.


Improve the desired profitability objective.
