Delta Air Lines has ordered 30 Boeing 787-10 aircraft, according to the Simple Flying headline. The headline says the airline will not receive any of the aircraft until 2031. In other words, the stated timing puts receipt in 2031 or later, rather than before that year.
Simple Flying’s summary describes a five-year wait and says it raises questions about replacements, engines and capacity. It identifies those three topics as questions associated with the wait, rather than reporting them as outcomes. The stated order quantity, aircraft model and timing are presented alongside those issues.
