NEW DELHI, June 1 (Reuters) - India's largest airline

IndiGo on Sunday announced an agreement with Air

France-KLM, Virgin Atlantic and Delta to

expand its long-haul services to North America, Europe and

Britain, the airlines said on Sunday.

Indigo has an extensive domestic network in India and is

expanding its international reach.

Once the partnership is complete IndiGo will be able to sell

flights under its own name on those operated by its partners out

of India, and onward travel from Amsterdam and Manchester on

select flights to Europe and North America.

IndiGo has an existing relationship with Air France-KLM and

Virgin Atlantic, and its Delta partnership is new.

U.S. carrier Delta has not flown to India since the

pandemic. CEO Ed Bastian told media at an airline summit in New

Delhi that Delta will restart direct services from the United

States to India over the next couple of years.

Delta is planning nonstop flights between Atlanta and Delhi,

subject to government approval, a joint statement said.

India is the world's third-largest air passenger market, and

is rapidly expanding its aviation industry.
