Delta Air Lines, which bought Northwest Airlines in October, plans to make major changes to aircraft orders both had previously placed with Boeing, according to The Wall Street Journal. Delta is likely to scale back a Northwest order for Boeing’s new, but delayed, 787 Dreamliner, and ask the manufacturer to expand a Delta order for the 777-200LR aircraft. The 777-200LR would better enable the combined carrier to continue pursuing Delta’s strategy to shift a greater percentage of its flights to long overseas routes. A change in orders from Delta is unlikely to significantly hurt Boeing as it has secured other customers for 787s, and the manufacturer is likely to be willing to expand its order book for the more expensive 777-200LR.
