A third part of Terminal 5 has recently been opened at Heathrow Airport, giving British Airways passengers improved facilities and more space.
The £340 million satellite terminal, known as T5 C, is intended to make travelling a smoother experience for customers.
Now, an additional three million customers will be able to access their aircraft using an "air bridge" rather than a bus each year.
Andy Lord, director of operations at British Airways, said: "Terminal 5 has transformed our ability to offer the very highest standards of customer service which our passengers rightly expect for punctuality, baggage handling and relaxing before their flight. We hope that T5 C will improve our overall performance even further."
There are 12 boarding gates at the new terminal, eight of which are designed to meet the needs of the Airbus A380S, which British Airways will introduce from early 2013.
Last month, Heathrow Airport also saw Air India move from its location in Terminal 3 to Terminal 4, which has recently been refurbished.
