Mumbai - IndiGo, India's largest airline in terms of fleet and market share, is eyeing the highly profitable United States market through an existing codeshare agreement with Turkish Airlines. In a joint filing the two airlines with the US Department of Transportation, have requested "expedited approval of the application", a standard procedure for such cases.

Vinay Malhotra, IndiGo's head of international sales, stated on Friday that the partnership with Turkish Airlines would improve passenger services from India to Istanbul and Europe. Upon approval, IndiGo will be able to offer flights to 12 US cities, including Atlanta, Boston, Chicago, Dallas-Fort Worth, Houston, Los Angeles, Miami, New York, Newark, San Francisco, Seattle, and Washington D.C.

A codeshare agreement enables passengers to easily transfer from one airline's flight to another using the same flight number.

According to Malhotra, IndiGo has already ordered aircraft from French manufacturer Airbus, which will provide a steady supply of aircraft until 2030.

"We presently have over 300 aircraft in operation and nearly 500 more on order. Of course, the expansion will depend on the frequency and timing of aircraft delivery. However, as and when we receive the aircraft, they will be deployed in the domestic market and some overseas," Malhotra told ANI.

Currently, IndiGo operates 1,800 flights per day, 10% of which are on international routes.
