International Airlines Group, the parent company of British Airways, has announced an order for up to 42 777X airplanes, including 18 orders and 24 options. The commitment, valued at up to US$18.6 billion at list prices, will be reflected on Boeing's Orders and Deliveries website once it is finalized. "The new 777-9 is the world's most fuel-efficient long-haul aircraft and will bring many benefits to British Airways' fleet. It's the ideal replacement for the 747 and its size and range will be an excellent fit for the airline's existing network," said Willie Walsh, IAG chief executive. "This aircraft will provide further cost efficiencies and environmental benefits with fuel cost per seat improvements of 30 percent compared to the 747. It also provides an enhanced passenger experience." British Airways has been modernizing its fleet – one of the largest in the airline industry – to more efficiently serve its extensive global route network. In recent years, the airline has introduced the super-efficient 787 Dreamliner family to replace its medium-sized widebody jets. The new 777-9 will replace British Airways' larger widebody airplanes, mainly the four-engine 747 jumbo jet. In ordering the 777-9, British Airways extends a long-running relationship with the popular 777 family. The airline is one of the largest 777 operators with a fleet of nearly 60 of the long-range jet. The airline last year committed to four more 777-300ER (Extended Range) jets via operating lease. "British Airways is one of the most iconic international carriers, now in its 100th year of connecting the world with its impressive route network. We are honored that British Airways has selected the 777X as part of its fleet for its next century. Together with the 787 Dreamliner, we are excited for the 777X to help British Airways build on its incredible legacy," said Kevin McAllister, president & CEO of Boeing Commercial Airplanes. "The 777-9, in particular, simply has no competitor in its class when it comes to efficiency and performance. It is the right-sized airplane for British Airways to efficiently serve long-range routes with heavy passenger demand." The selection by IAG and British Airways puts the 777X at 358 orders and commitments from eight customers.
