Global aerospace and technology giant Thales has signed a massive 11-year avionics maintenance support agreement with IndiGo, India’s largest airline. The deal covers IndiGo’s current Airbus A320 fleet as well as over 800 new planes scheduled for delivery in the coming years. With this, more than 1,200 aircraft will fall under Thales’ long-term maintenance programs.
The contract underlines IndiGo’s ambition to expand its operations globally while ensuring world-class safety and efficiency standards.
Scope of the 11-Year Contract

The maintenance pact is designed around Thales’ signature “By The Hour” and “Repair By The Hour” programs. These models allow airlines to pay based on actual flight hours, ensuring predictable costs, reduced downtime, and quick turnaround for avionics repairs.
Repairs will be handled at Thales’ advanced Maintenance, Repair, and Overhaul (MRO) facility in Gurugram, Haryana, cementing India’s role as a key hub for aerospace servicing.
Electronic Flight Bag Rollout Extended
Alongside the maintenance deal, IndiGo has also extended its partnership with AvioBook, a Thales subsidiary, for another five years. AvioBook provides the airline’s Electronic Flight Bag (EFB) solution, which has already been authorized by India’s Directorate General of Civil Aviation (DGCA) for paperless cockpit operations.
The EFB system integrates digital flight documents, operational data, and navigation tools into tablets, replacing bulky paper manuals and reducing cockpit clutter.
Impact on Daily Flight Operations
According to Thales, AvioBook has already proven its value across IndiGo’s operations:
- Used across the entire IndiGo fleet for over a year.
- Helps cut down on annual paper consumption significantly.
- Streamlines flight operations on more than 2,000 daily flights.
With the extension, AvioBook will continue supporting 650,000 flights annually for the next five years, boosting operational efficiency and environmental sustainability.
Why This Deal Matters
For IndiGo, this long-term contract provides stability and predictability in managing one of the world’s fastest-growing fleets. The airline currently operates more than 350 aircraft and has over 800 new Airbus A320 family aircraft on order, making it one of the largest single-airline orders globally.
For Thales, the contract reaffirms its strategic presence in India and strengthens its role in providing next-generation aerospace technology solutions. Thales has been operating in India since 1953, with deep involvement in defence, aerospace, and digital innovation.
Sustainability Benefits
The move toward paperless operations is also a green milestone for IndiGo. By digitizing flight data, the airline not only reduces paper waste but also ensures faster access to updated information, cutting the risk of manual errors. Combined with modern avionics support, this will contribute to lower fuel consumption, fewer delays, and safer skies.
Global Aviation Context
This agreement places IndiGo alongside global carriers that rely on long-term maintenance partnerships to manage mega-fleets. With aviation costs rising and competition tightening, predictive maintenance and digital integration are becoming crucial for airlines to remain profitable while keeping safety uncompromised.
The deal also highlights India’s growing prominence in global aviation, as domestic carriers like IndiGo push aggressively into international markets.
What Lies Ahead for IndiGo
With both its fleet expansion and operational digitalization on track, IndiGo is gearing up for a transformative decade. New international routes, increased long-haul connectivity, and strengthened partnerships with technology leaders like Thales signal a shift from being a low-cost domestic airline to a global aviation powerhouse.
