Five turnaround blind spots 
that increase delays and costs

Most turnaround delays do not begin with a delayed flight. They begin much earlier, through operational blind spots that quietly reduce visibility, limit recovery options and increase disruption costs. This article explores five of the most common causes and the questions every operations team should be asking. 

Fuel remains one of the largest cost factors for airlines. According to IATA, airlines are expected to spend around USD 350 billion on fuel in 2026, accounting for approximately 31,4% of total operating costs. As fuel costs rise, the financial impact of each departure delay increases. At the same time, airline-related operational issues such as passenger and baggage handling, and technical processes continue to contribute significantly to departure delays across the network. Many of these disruptions emerge during aircraft turnaround, where small coordination gaps, delayed information or limited visibility  affect on-time performance and propagate throughout the day. 

The following points highlight five operational blind spots that frequently contribute to delay propagation and additional operational costs. The accompanying questions are intended to prompt a critical review of existing turnaround processes. They offer a foundation for strategic discussions around visibility, coordination, and data-driven decision-making in turnaround management. Organizations that systematically address these blind spots position themselves to maintain operational resilience and respond effectively to disruptions. 

Increasingly, airlines and ground handlers are supporting these operational decisions with integrated turnaround management solutions that improve visibility, coordination, and decision support across the turnaround process. 

1. Limited Visibility Across Ground Activities

Refueling, boarding, baggage handling, catering and crew coordination depend on each other. According to EUROCONTROL, airline-related activities such as passenger and baggage handling, and technical processes contributed an average of 4.5 minutes of delay per flight in 2023. When teams work with different information or limited visibility, dependencies between activities can remain hidden until operational consequences become apparent. 

This lack of transparency forces teams into reactive coordination, reduces available recovery options, and puts departure performance at risk. 

Questions to consider 
✓ Can all turnaround milestones be monitored in real time? 
✓ Are dependencies between activities visible to all stakeholders? 
✓ Do teams share the same operational view? 

2. Identifying Disruptions Too Late 

Many operational systems report deviations once they have already impacted the turnaround process. EUROCONTROL data shows that reactionary delays added an average of 8.2 minutes per flight in 2023, illustrating how quickly disruptions can spread across subsequent operations. Once issues surface, the window for cost-effective mitigation narrows rapidly leaving teams with limited, often expensive, recovery options. Teams have less flexibility to react, operational pressure increases, and delays are more likely to have an impact throughout the day. What begins as a local disruption can affect multiple flights and stakeholders. 

Questions to consider 
✓ Are bottlenecks identified before departure performance is affected? 
✓ Do teams receive early warnings when a turnaround starts drifting off plan? 
✓ Can corrective actions be taken before delays become critical? 

3. Critical Path Uncertainty 

Not every delayed activity affects departure time. Operations teams need to understand which task currently drives departure risk. Without a clear view of the critical path, resources may be directed toward activities with limited operational impact. This can slow decision-making, create conflicting priorities, and reduce the effectiveness of operational interventions. 

Questions to consider 
✓ Is the current critical path visible during every turnaround? 
✓ Can teams focus resources on the activities that matter most? 
✓ Are operational priorities adjusted when conditions change? 

4. Cost Context in Delay Management 

Operational decisions that accelerate departures may not always be financially optimal. The true cost of disruption is shaped by passenger connections, crew logistics, aircraft rotations, and broader network effects - factors that can dramatically alter the financial implications of any intervention. Focusing exclusively on schedule recovery might obscure crucial cost drivers. A decision that reduces delay minutes can still increase passenger disruption, rebooking costs or downstream operational impacts elsewhere in the network. Without visibility into these trade-offs, decisions are often made under time pressure with limited understanding of their overall business impact. 

Questions to consider 
✓ Are passenger impacts considered during disruption management? 
✓ Can alternative actions be compared based on cost implications? 
✓ Are operational decisions supported by business impact data? 

5. Stakeholder Communication Gaps 

Ground operations involve multiple teams, systems, and locations. Delays often grow when information is incomplete, inconsistent, or too late. When stakeholders work with different data or receive updates at different times, coordination becomes more difficult. This can lead to avoidable delays, uncoordinated actions, and reduced operational reliability across the turnaround process. 

Questions to consider 
✓ Do all stakeholders receive operational updates at the same time? 
✓ Are critical changes communicated automatically? 
✓ Is information consistent across teams and systems?
