LAN Airlines and affiliate carrier TAM Airlines have revealed their new unified cabin design.
The design was inspired by South America's colours and textures.
In the short-haul cabins, it incorporates four colours and two different leather textures, while in the new long-haul cabins, the fabric incorporates more cloth elements to "create maximum comfort for longer flights".

It is the first unified cabin design in the LATAM Airlines Group.
Two aircraft already feature the new cabin — they are a LAN A320 servicing domestic routes within Chile and a TAM A321 servicing domestic routes within Brazil.
Moving forward, all of the carriers' new A320 and A321 short-haul aircraft will feature the new cabin interior and seats.

Beginning in 2015, LATAM will introduce two new aircraft, the B787-9 and the A350-900, into its long-haul fleet featuring the new cabin design and offering two classes of service, economy and premium business.
Jerome Cadier, LATAM's marketing vice-president, said: "Every element was carefully selected and designed to include the best elements of the countries in the region to create a world class project.
"With these objectives in mind, the rich wood textures of the Amazon are present in several elements throughout the cabin, including part of the floor and details on the seats."

He added: "The fabric, textures, colors, and patterns are reminiscent of the beautiful landscapes of our region. Even the iconic beaches of Ipanema were a source of inspiration for the cabins."
In January, TAM Airlines announced it would cancel its London Heathrow to Rio De Janeiro route from March, but will temporarily reopen the service during this summer's football World Cup in Brazil (see news, January 14).
