Air India and IndiGo are two of India’s leading airlines, but they follow different business models and strategies. Air India focuses on full-service travel and international connectivity, while IndiGo primarily follows a low-cost model. Their fleet choices, operating costs, pricing, networks and expansion plans influence their competitive positions in India’s aviation market.
1. Fleet Structure and Utilisation
Air India
Air India operates narrow-body and wide-body aircraft for domestic and international services. Its fleet includes Airbus A320-family aircraft, A350s and Boeing aircraft, with different types serving different routes. Fleet modernisation aims to improve fuel efficiency, passenger comfort and operational reliability.
IndiGo
IndiGo primarily operates Airbus A320 and A321-family aircraft, along with ATR aircraft on selected regional routes. It also uses leased wide-body aircraft for selected international services. Its largely standardised narrow-body fleet supports efficient training, maintenance and aircraft utilisation.
2. Cost Structure
Air India
Air India’s costs include aircraft maintenance, employee expenses, fuel, airport charges and fleet investment. Modernising its aircraft and improving operational efficiency are important parts of its transformation. Its full-service model also involves providing a wider range of passenger services.
IndiGo
IndiGo focuses on cost control through fleet standardisation, efficient aircraft utilisation and streamlined operations. Its low-cost model offers basic fares with optional services available for additional charges. However, fuel prices, aircraft availability and other operating expenses continue to affect its costs.

4. Employee Management
Air India
AirIndia is working to improve employee training, productivity and operational processes during its transformation under the Tata Group. Integrating operations, modernising systems and maintaining consistent service standards require significant coordination. Training and workforce development remain important to its long-term plans.

IndiGo relies on standardised procedures, employee training and operational planning to support its extensive flight network. Efficient coordination between ground teams, cabin crew, pilots and maintenance staff helps support daily operations. Its performance also depends on staffing levels, training and the wider operating environment.
5. Domestic Market Share and Brand Perception
Air India
AirIndia has a long history in Indian aviation and an important role in international connectivity. The merger with Vistara strengthened its full-service operations, while fleet and cabin upgrades are part of its transformation. It continues to compete with IndiGo in the domestic market and other airlines internationally.
IndiGo
IndiGo holds the leading position in India’s domestic aviation market. In June 2026, it had a 66.3% domestic market share, compared with 23.9% for the Air India Group. These figures reflect that month’s traffic data and may change over time.
6. Pricing Strategy
Air India
Air India’s fares vary according to route, demand, cabin class and fare conditions. Its full-service offering and premium cabins allow it to serve different passenger segments. To attract price-sensitive travellers, it also needs to remain competitive on domestic routes.
IndiGo
IndiGo uses demand-based pricing, with fares varying by route, booking time and seat availability. Passengers can select additional services according to their needs and budget. This model helps the airline appeal to travellers seeking competitive fares.

Its frequent services and connections provide passengers with a wide range of travel options. The airline also serves regional routes, including routes supported by regional connectivity initiatives where applicable.
8. Customer Experience
Air India
AirIndia is investing in cabin refurbishment, upgraded aircraft, digital services and improvements to its passenger experience. Its goal is to deliver more consistent service while modernising its operations. The experience can vary according to the aircraft, cabin, route and stage of the upgrade programme.
IndiGo
IndiGo focuses on affordable travel, frequent flights and streamlined passenger services. Digital booking tools and optional service choices help passengers manage their journeys. As with other airlines, delays and disruptions can occur, so punctuality and service performance should be assessed using current operational data.
9. Future Plans
Air India
AirIndia has expanded its aircraft commitments to support fleet modernisation and growth. In January 2026, it added 30 Boeing aircraft to its firm orders and converted 15 Airbus A321neo orders to A321XLRs, taking its total firm aircraft orders to 600. The airline plans to use its growing fleet to improve efficiency and expand its route options.
IndiGo
IndiGo has placed major orders for Airbus A320-family aircraft to support its future growth. It also increased its firm Airbus A350-900 order to 60 aircraft in October 2025, supporting its long-term international expansion plans. These aircraft commitments are intended to expand its reach beyond its traditional narrow-body network as deliveries progress.
Air India vs IndiGo
AirIndia and Indigo compete through different business strategies. Indigo’s extensive domestic network and low-cost model have helped it become India’s leading domestic airline by market share, while Air India is modernising its fleet and strengthening its full-service and international operations. Their future performance will depend on operational reliability, cost management, passenger experience and successful fleet expansion.
