Diversion Management



Diversions are an expensive, chronic, and disruptive element of flight operations, costing US carriers at least $300 million annually for domestic flights alone.* With the PASSUR Diversion Management solution, airports are proactively notified of diversions – status, location, duration – in advance of any other source, so they can proactively manage the customer, operations, and regulatory demands triggered by diversions.

  • A diversion is not a single, discrete event but rather a set of cascading actions that cause severe disruptions to airline schedules, major costs, and significant passenger frustration and ill will.

*Derived from industry benchmark cost ranges for narrow-body domestic diversions only; based on DOT ASQP annual reported diversions from top 10 US carriers, US to US diversions only.

What’s New

Regional Diversion Management (RDM)

Addresses the problem of highly disruptive large diversion events when a small set of airports get overwhelmed with diversions, while other airports have unused capacity. The result is extended delays, cancellations, and disrupted schedule recovery.

  • Airlines: need to know where everyone is diverting (not just their own flights) and diversion airport “capability status” (gates, fuel, deicing fluid, hardstands)
  • Airports, CBP, and Ground Handlers: need to know how many diversions are headed to them, what type of aircraft, which airlines, and whether crews are likely to time-out

PASSUR RDM addresses these challenges by creating the first-ever platform that ensures real-time information exchange and coordination between airports, airlines, and other key stakeholders during large scale diversion events, by providing:

  • Detailed information about all regional diversion activity — en route, on ground, in recovery
  • Detailed information about airport diversion service capability
  • Instant communication among all key stakeholders

PASSUR’s independent tracking, alerting, and statusing of diversions enables airports to be proactive when preparing to accommodate diversions to the airport to prevent extended on-board tarmac delays, facilitate quick diversion turnaround and recovery, and prepare staffing and other resources for flights that were diverted from the facility and recovered back to the original destination.


PASSUR’s Diversion Management program is part of an integrated suite that reduces costs and constraints gate-to-gate, powered by the largest commercial traffic management surveillance network in the world. It provides the data granularity, completeness, and precision needed to create predictive, real-time, post-operational visibility into diversions.

  • Long on-board tarmac delays
  • Diversion turn
  • Diversion recovery
  • Prepare for inbound diversions
  • Help to handle landed diversions expeditiously
  • Prepare Customs and Border Protection (CBP), terminal facilities, ground transportation, and other staffing and infrastructure resources
  • Alert stakeholders to diversion capacity and current status

* Derived from the industry benchmark cost ranges for narrow-body domestic diversions only, and based on DOT ASQP annual reported diversions from top 10 US carriers, US to US diversions only.

  • Diversion Management module
  • Tarmac Delay Management module
  • Surface Management module
  • Connectivity and Collaboration platform
  • This solution is used by airlines to manage holdings and diversions for 25% of the flights in the NAS (and increasing).
  • 12 major North American airports manage surface operations on the PASSUR platform.
  • 100+ airports manage major events and disruptions on the PASSUR Connectivity and Collaboration platform.
Snapshot Case Studies
  • During the Chicago ATC fire of 2014, Diversion Management was coordinated on the PASSUR platform with the airlines in real time. As a result, although there were 89 diversions from ORD, they were spread out among 34 airports – and no single airport received more than 11% of the diversion total.
  • A major Northeastern airport that uses PASSUR Diversion Management reports that it regularly receives alerts to inbound diversions in advance of FAA flight plan changes or airline advisories.
  • One airline that has deployed the Diversion Management solution system-wide reported an 11% reduction in diversions in the first year of the program – 108% higher than its original goal. This meant approximately 10,000 passengers who arrived at their intended destination instead of being disrupted through diversion to an alternate airport.
