A British Airways (BAL) deal has been confirmed for 2019, after the airline said it would buy the long-serving subsidiary of US carrier United Continental Holdings (UAL).
British Airways, which operates more than 4,000 UK routes, said the deal would be worth up to £30 billion ($44 billion).
It was announced at the London Air Show.
The airline said the sale would be made to British Airways by the end of 2019, with a new entity to be formed by 2021.
The new entity will continue to operate the current aircraft, including the Boeing 777X, and will also operate the airline’s fleet of Airbus A330 jets.
The deal is expected to be completed by 2021, and BA said it is expected that the new entity, BA UK, would have “major opportunities” in the UK and the US.
BA has been the UK’s main airline for decades.
It is one of the UKs largest airlines, and is one the countrys largest carriers by revenue.
The company also owns Emirates, which also operates in the US, and has a stake in rival Norwegian.
