JFKIAT reduce ground delays by 5 minutes per flight with Assaia

Cost saving potential of $40 million per year

JFK International Air Terminal (JFKIAT) is one of the most active air terminals in the New York area, serving 30 international and domestic airlines with an annual passenger volume of 21.8 million travellers in 2018. The terminal serves 24 airlines and works with a range of ground handlers, resulting in a need for maximum visibility of operations between all stakeholders on the turnaround to reduce delays and ensure a safe apron environment.


JFKIAT sought to maximise their turnaround efficiency with real-time alerts and data to ensure gates were available on time for incoming flights. They needed notifications to ensure that ground handlers were adequately prepared for incoming flights - from refuelling and catering services all the way down to baggage loading. JFKIAT needed not just to understand but also improve turnaround performance while minimising delays in the process.


Assaia leveraged their proprietary Predicted Off Block Time (POBT) technology to optimise on-time arrival gate availability and alert ground handlers in real-time. This algorithm considers the aircraft model, landing site, weather conditions, the airport as well as passenger count along with real-time data about the situation on the apron for optimal efficiency. Assaia’s algorithms have tracked millions of turnarounds across more than 30 airports.

Through the Stand Clear solution, JFKIAT is able to spot any potential safety hazards or delays in a timely manner - allowing for an increased level of assurance when it comes to employee safety, passenger comfort and punctuality. This also helps reduce overall fuel consumption and carbon emissions, ultimately resulting in streamlined operations that benefit everyone involved.


  • Average reduction in ground delays of 5 minutes for all flights managed by Assaia, resulting in a cost-saving potential of $40 million per year
  • Increased capacity to handle additional flights with the same number of gates.
  • The percentage of occasions where the gate was clear upon arrival of aircraft has increased by 25%
  • Less waiting on the turnaround means higher arrival punctuality, and therefore departure punctuality, translating into a better passenger experience, and a reduction in fuel consumption and carbon emissions.
