British Airways will add its code onto a few destinations on IndiGo's network, and customers can enjoy improved connectivity between India and the United Kingdom for travel, the airline said in a statement.
Codeshare flights will be available for booking by Thursday for travel from October 12 subject to government approval.
British Airways operates up to 56 flights a week to five Indian cities, including Delhi, Mumbai, Chennai, Bangalore, and Hyderabad.
British Airways is now able to add three additional routes, thanks to the codeshare partnership with IndiGo.
The agreement means that customers traveling from Rajkot to London or moving through London Heathrow will be able to connect to their destination on a single ticket.
's extensive network in India.. s extensive network in India,' said Abhijit Dasgupta, senior vice president for network planning and revenue management at IndiGo.
Codesharing makes it possible for an airline to book its passengers on its partner carriers and provide seamless travel in regions where it has no presence.
IndiGo has already teamed up with Turkish Airlines, Qatar Airways, American Airlines, Air France-KLM, Australian carrier Qantas and Virgin Atlantic. With Jetstar, IndiGo has an interline pact with IndiGo.
A pact to issue and accept tickets for flights operated by the partner airline is known as an interline arrangement.
