According to IndiGo, the arrangement is expected to expand AEGEAN’s access to India and South Asia, while giving IndiGo passengers additional options across AEGEAN’s domestic and European network.

IndiGo has already announced its plans to operate direct flights to Athens starting early January 2026, while on the other hand, AEGEAN has also announced flights to India by March 2026. IndiGo will begin with six weekly flights to Athens while AEGEAN will launch five weekly flights to Delhi and subsequently, 3 weekly services to Mumbai.

Through the agreement, AEGEAN passengers will gain access to more destinations in India and South Asia, as the airline’s flight code “A3” will be placed on a number of IndiGo-operated routes.

IndiGo’s “6E” code, in turn, will be added to AEGEAN’s domestic and European services from its hub at Athens International Airport. This arrangement is intended to provide smoother travel between India, Greece, and South Asia, IndiGo said.

According to both airlines, passengers will be able to book integrated itineraries with benefits such as through check-in. Specific details on the codeshare routes are expected to be announced later.

Pieter Elbers, CEO of IndiGo, said, “We are pleased to announce our partnership with AEGEAN, marking a significant step forward in our mission to give wings to India and enhance global connectivity. This collaboration enables our customers to conveniently book seamless itineraries on an expanded, integrated network across both airlines, including beautiful islands in Greece and other regional European destinations.”

Eftichios Vassilakis, Chairman of AEGEAN, commented, “We are delighted to establish a strategic partnership with IndiGo, one of the fastest-growing airlines in the world. This step expands AEGEAN’s footprint beyond Europe into one of the world’s most dynamic markets, strengthening the bridge between Greece and India.”
