The first UK carrier to operate Boeing 777-300ER is British Airways. UK’s national airline just has taken delivery of first of the six planes on order.

The newly registered G-STBA will have a four class interior, 297 seats and it is the first aircraft delivered to BA this year. By the end of the year, two more planes should be scheduled for flights under the British Airways livery.

BA is taking three more Boeings 777 by early 2012, and the executives of the company are already proud to announce that the interior of the aircraft’s cabin has been completely modernised. The new in-flight entertainment system will also assure the customer satisfaction by providing 50% more choices on movies, television and music products, the representatives of BA say.

“It is the aircraft first to be fitted-out with our new ‘World Traveller’ and ‘World Traveller Plus’ cabins”, Willie Walsh, CEO of British Airways, says.

The 777 delivered to the UK carrier will also feature BA’s ‘First’ and ‘Club World’ interiors.

British Airways therefore becomes the third European carrier to operate 700-300ER, after Turkish Airlines and Air France-KLM. The twin-engine jet airliner is powered by a couple of General Electric 90-115B turbofans, currently the most powerful used engines in use. The range of this lovely aircraft is 7,930 nautical miles (14,690 km).
