French technology group Thales has signed an 11-year avionics maintenance support contract with IndiGo, India’s largest airline, for its Airbus A320 family fleet. The deal extends to over 1,200 aircraft, including the 800-plus planes scheduled for future delivery.

The agreement includes Thales’ ‘By the Hour’ and ‘Repair by the Hour’ programmes, with repairs to be carried out at its maintenance facility in Gurugram. Additionally, IndiGo has extended by five years its deal with AvioBook, a Thales subsidiary, for Electronic Flight Bag solutions.

The paperless AvioBook Flight system, already deployed across IndiGo’s fleet, has reduced paper usage and streamlined flight operations on over 2,000 daily flights. The extended contract will continue to support approximately 650,000 flights annually.

Thales, listed in Paris and operating in India since 1953, is a global leader in aerospace, defence, and digital technologies. The long-term partnership with IndiGo is expected to enhance operational efficiency while supporting sustainable aviation practices.
