An airline runs hundreds of aircraft, thousands of crew and millions of passengers against a schedule that weather, ATC and maintenance can break at any hour, and a single multi-hour disruption ripples through the next 48.

Solace connects the systems that each hold part of the picture, so the whole operation adjusts to the same event at the same time.

  • Propagate schedule changes to ops, crew, gate, bag and customer systems in seconds
  • Span legacy on-premises PSS and cloud-native services in a single event mesh
  • Modernize integration with no rip-and-replace, thanks to pre-built bridges to what you run today: IATA Type B (PNL/ADL/BSM), IBM MQ, Kafka, SAP, TIBCO, etc.

What can airlines do with Solace?

Disruption Management Stop One Delay From Becoming
Tomorrow's Cancellations

Disruptions are unavoidable — what separates carriers is how fast the whole operation learns the plan has changed.

Solace publishes each schedule deviation once and delivers it everywhere at once: crew, passengers, bags, gates, notifications and MRO all act on the same event within seconds.

That same stream gives AI agents current state instead of a stale snapshot, so recommendations flow back into the systems that act on them.

Crew Scheduling and Rostering Re-Crew with Continuous
Crew-Legality Validation

When a flight moves, every crew option has to clear duty-time and qualification rules before it can be offered.

Solace streams crew availability, duty-time clocks, qualifications and pairings across crew systems the moment they change, so rostering engines validate FDP limits, rest and qualifications continuously and surface only legal options.

Baggage Tracking Know Where Every Bag Is,
at Every Handover

IATA Resolution 753 requires custody tracking at every handover, and a mishandled bag is a failure passengers remember for years.

Solace carries scan and RFID events between departure control, baggage systems, handlers and the passenger app, so bag location is a live fact, and transfer bags re-flow automatically when a connection changes.

Passenger Experience and Loyalty Tell Passengers What
Changed Before They Ask

Passengers judge an airline against consumer apps, and a notification that lags the operation by ten minutes is worse than none.

Solace streams check-in, boarding, gate and disruption events to web, mobile and customer comms the instant they reach operations, while loyalty and in-trip events feed the offer engine in real time.

Legacy Messaging Modernization Retire TIBCO and MQ Without
Grounding the Operation

When the messaging layer fails, flights are delayed — and most carriers still run large TIBCO or MQ estates alongside cloud-native services never built to talk to them.

Solace replaces those estates incrementally across hybrid topologies — on-prem and cloud on one mesh — over open protocols, and coexists with Kafka where teams already use it.

Some Airport Success Stories

United Airlines

Problem: Outages and slow recovery in a hybrid estate held together by more than 100 TIBCO instances made every disruption more expensive than it needed to be.


Solution: A hybrid event mesh across on-premises systems and AWS coordinates flight operations end to end, with Event Portal cataloging and governing the event landscape as teams migrate off TIBCO.


Outcome: Streamlined operations, fewer outages, faster recovery and a real-time foundation for AI initiatives. A specific figure still needs to come from the account team — TIBCO instances retired or recovery time saved are the natural metrics.


Get the Full Story

Large Airline based out of Dubai

Problem: Flight delays were being caused by failures in the messaging layer itself — a TIBCO EMS estate carrying operational traffic it could no longer support reliably.


Solution: Replacement of TIBCO EMS with Solace globally, with an Event Mesh spanning on-premises and cloud environments across AWS-Dubai, Bahrain, Dublin, Singapore, and Azure Dubai, enabling reliable and real-time distribution of operational events across locations.


Outcome: ReNo flight delays have been attributed to messaging-layer issues since Solace was introduced, with two years of operational stability.

Large Airline based out of Qatar

Problem: Delayed crew updates across training, certifications, availability, sickness, rosters and pairings created inconsistent operational views and slowed crew recovery. This also increased the risk of crew legality and duty-time violations when the latest crew status was not available across systems.


Solution: Implement an event-driven architecture with Solace to distribute every crew-related change in real time across Crew Management, Rostering and Operations Control, ensuring all systems work from the latest crew status and legality picture.


Outcome: Faster crew recovery, improved crew utilization, reduced manual reconciliation and stronger crew legality and duty-time compliance, helping prevent assignments that could result in regulatory violations or operational disruption.

Large South American Airline

Problem: An event-driven modernization program needed a way to give application teams autonomy without fragmenting the airline's operational data across incompatible platforms.


Solution: Solace as the enterprise event backbone running alongside Kafka for application teams, with Event Portal for cataloging and governance.
