American Airlines and IndiGo on Tuesday announced that they have entered into a codeshare agreement which allows the former to sell seats on the Indian carrier’s flights operating on 29 routes.

“The codeshare, which will require US and Indian governments’ approvals, is expected to begin in October, as American launches new service between New York (JFK) and Delhi on October 31 this year and between Seattle and Bangalore on January 4, 2022,” the joint statement mentioned.

The one-way codeshare agreement will place American’s code on 29 of IndiGo’s domestic routes, providing a convenient option for American Airlines customers to travel within India after landing in Bangalore or Delhi.

Once the one-way codeshare agreement comes into force, American will be able to sell seats — on its distribution system — of IndiGo flights on the 29 selected routes.

In a two-way codeshare agreement, each airline on its distribution system can sell seats of other’s flights. IndiGo at present has a two-way codeshare agreement with Turkish Airlines and a one-way codeshare partnership with Qatar Airways.

Vasu Raja, chief revenue officer, American Airlines, said: “Whether our customers are travelling for business or pleasure, this new partnership makes it easy to reach all four corners of India.”

“Today we’re adding 29 new routes to our map as a result of this agreement, providing customers with even more options,” Raja said.

IndiGo is India’s largest airline by number of passengers carried. With its fleet of 275+ aircraft, the airline operates more than 1,100 daily flights, connecting 70 domestic destinations and 24 international destinations.
