Behind Every Flight: The Operations That Keep IndiGo Moving

- By Pratyansh Raj

When we think about an airline, we often think about the aircraft, the destination or the experience of travelling. But behind every flight is a complex operational system that has to work with remarkable precision.


I recently found myself reading extensively about IndiGo and its operational model, and what fascinated me was how many management decisions are involved in something that passengers experience as simply “a flight.”


Airline operations are essentially a race against time. An aircraft generates revenue only when it is flying, which makes efficient utilisation extremely important. Once an aircraft lands, several activities need to happen within a limited turnaround window—passengers have to disembark, the aircraft needs to be cleaned, baggage has to be handled, catering and other services have to be completed, passengers need to board, and the aircraft has to be ready for its next departure.


A delay in one activity can create a chain reaction across the entire schedule.

This makes capacity planning, scheduling and process coordination critical components of airline operations. IndiGo's business model has historically focused on operational efficiency, a standardised fleet approach and relatively quick aircraft turnaround. These operational choices support its ability to offer frequent services across a large network.


However, operational efficiency does not mean simply doing things faster. It means designing a system in which different activities work together with minimum disruption.

For example, having more aircraft does not automatically create better operations. The airline needs pilots, cabin crew, airport slots, maintenance facilities, ground-handling arrangements and appropriate scheduling. Every additional flight creates a requirement for coordination across multiple resources.


While reading about IndiGo's operations, I was particularly interested in how a seemingly simple customer experience is actually the outcome of hundreds of interconnected operational decisions.


This became even more meaningful when the topic was discussed in my class at JIMS Kalkaji. What began as a discussion about airline operations soon moved towards concepts such as capacity utilisation, process efficiency, bottleneck management, quality, resource allocation and supply-chain coordination.


One point that stood out for me was that operations management is often invisible when it is working well. Passengers rarely think about the operational planning behind an on-time departure. They notice it only when something goes wrong—a delayed flight, misplaced baggage, a shortage of resources or a disruption in the schedule.


That is perhaps one of the biggest lessons from studying operations.

Good operations are not necessarily noticed; they are experienced.


The IndiGo example demonstrates that operational excellence is not created by one decision. It comes from hundreds of interconnected decisions being executed consistently.

For management students, this is an important perspective. Whether it is an airline, hospital, manufacturing company, e-commerce platform or restaurant, the customer ultimately experiences the outcome of the organisation's operations.


Behind every successful customer experience is a system—and understanding that system is at the heart of Operations Management.

The New Currency of Careers Is Continuous Learning

 -By Umama Mahmood 103/ PGDMB /2026 There was a time when completing a degree and gaining a few years of experience could provide a relatively stable career path. Today, that assumption is becoming increasingly difficult to sustain. Technology, artificial intelligence and changing business models are continuously redefining what  organisations  expect from their employees. The conversation around employability is therefore shifting from “What qualification do you have?” to “What can you learn, unlearn and apply?” The World Economic Forum and the IMF have both highlighted the growing importance of skills adaptation as technology changes the nature of work. The IMF notes that new skills and occupations are emerging alongside automation, making continuous learning increasingly important for both employees and  organisations . This does not mean that traditional qualifications have lost their value. Rather, qualifications provide a foundation, while continuous learning d...

Leadership in the Age of Change Is About Creating Confidence

- By Suhani Kumari 05/PGDMB/2026   Change has always been part of  organisational  life. What has changed is the speed at which  organisations  are expected to respond to it. Artificial intelligence, economic uncertainty, evolving employee expectations and changing customer  behaviour  are forcing  organisations  to make decisions faster than ever before. In such an environment, leadership cannot simply mean having all the answers. In fact, one of the most important qualities of a modern leader may be the ability to create confidence when all the answers are not yet available. Employees often experience  organisational  change differently from senior management. For leaders, a new technology may represent innovation and growth. For employees, the same technology may raise questions about job security, workload, skills and future responsibilities. If these concerns are ignored, resistance is likely to increase. This is why communicat...
