The group, which includes affiliates Latam Airlines Peru, Latam Airlines Colombia and Latam Airlines Ecuador, will start operating the new codeshare arrangement in the first quarter of 2020, subject to regulatory approval.

Its current arrangements with American Airlines will come to an end on 31 January next year.

Once the new arrangements with Delta commence, Latam customers will have the opportunity to connect with up to 74 onward destinations in the US and Canada while Delta passengers will have the option of 51 destinations in South America.

Enrique Cueto, group chief executive at Latam Airlines, said: “These codeshares mark an important milestone in Latam’s journey towards offering the best connectivity and customer experience in the Americas.”

The codeshare arrangement is just one part of the framework agreement that was agreed in September.

The arrangement will also see Delta invest $1.9 billion for a 20% stake in Latam as well as a further $350 million to support the establishment of the strategic alliance contemplated in the framework agreement.
