The UK’s International Airlines Group (IAG) is set to launch Level, a new low-cost long-haul airline brand.

Scheduled to enter service by June, Level will operate from Barcelona, Spain, to Los Angeles and San Francisco, US.

With two new Airbus A330 aircraft, the new airline will also cover Buenos Aires, Argentina, and Punta Cana, Dominican Republic.

The aircraft to be used by Level will be equipped with 293 economy and 21 premium economy seats.

"This will allow customers to connect from Vueling's extensive European network onto Level's long-haul flights."

IAG chief executive Willie Walsh said: “Level will become IAG's fifth main airline brand alongside Aer Lingus, British Airways, Iberia and Vueling. It will complement our existing airline portfolio and further diversify our current customer base.

“Barcelona is Vueling's home base and this will allow customers to connect from Vueling's extensive European network onto Level's long-haul flights."

Level flights will initially be operated by IAG partner airline Iberia and its cabin crews.

The new airline brand will also create up to 250 jobs in Barcelona.

IAG currently has 548 aircraft that travel to 268 destinations worldwide and carry more than 100 million passengers a year.

Established in January 2011, IAG is the parent company of Aer Lingus, British Airways and Vueling.
