"We continue to watch trends and speak to our customers to determine what the market will require in the years to come," Doug Alder, a Boeing spokesman, said Friday in an email. "Today, we're very focused on our current development programs: the 777X, the 737 Max and the 787-10."
Air Astana, which is 49 percent owned by British defense company BAE Systems, has issued a request for proposals for 11 stopgap jets to replace five 757s and a handful of other aging planes, with Airbus's re-engined A321neo emerging as the best prospect for the niche, Foster said.
Air Astana is seeking deliveries starting in 2017, with the planes on eight-year leases expiring from about the time that a 757 successor would become available in 2024 or 2025, the executive said. Discussions are under way with lessors including AerCap Holdings and Air Lease Corp., and an A321 order probably will be announced as soon as October, he said.
While Boeing delivered the last single-aisle 757 in 2005, the jet remains popular with carriers such as Atlanta-based Delta Air Lines Inc. for a range that's unmatched by any narrow- body jet currently manufactured.
Chief Executive Officer Jim McNerney said in May that Boeing was contemplating a new aircraft with comparable capabilities, though saw no immediate need to produce the plane.
Boeing's design would meld features from the single-aisle 737 Max, which seats as many as 192 people, and the twin-aisle 787-8, with a capacity for 242 travelers, McNerney said. The planemaker used a similar approach when it developed the 757 jointly with the larger 767 in the 1980s.
Air Astana has just taken delivery of a third Boeing 767 that may be the last passenger variant off the assembly line, according to Foster, a former CEO of Royal Brunei Airlines and senior executive at Hong Kong's Cathay Pacific Airways Ltd.
The Kazakhstan airline also has orders for three 787 Dreamliners for delivery in 2017 and 2019 that will be used on U.S. routes, Foster said.
Founded in 2002 as part of a planned BAE deal to sell radar equipment to the Kazakh government, Air Astana has expanded to offer 60 services, 38 of them international.
