Delta Air Lines issued a statement on Northwest Flight 188 investigation regarding the company's cooperation with the National Transportation Safety Board (NTSB) and the Federal Aviation Administration (FAA) in the investigation of Northwest Flight 188. Delta and its Northwest operating subsidiary continue to openly and fully cooperate with the NTSB and FAA to complete the investigation. The pilots in command of Northwest Flight 188 remain suspended until the conclusion of the investigations into this incident. 

Using laptops or engaging in activity unrelated to the pilots' command of the aircraft during flight is strictly against the airline's flight deck policies and violations of that policy will result in termination. Delta CEO Richard Anderson said: "Nothing is more important to Delta than safety. We are going to continue to cooperate fully with the NTSB and the FAA in their investigations."  

The NTSB earlier issued a public release highlighting the initial findings of its investigation into the incident, including evidence that the pilots involved said they were distracted at cruise altitude between San Diego and Minneapolis-St. Paul. The NTSB's press release stated that the pilots said in interviews that "there was a concentrated period of discussion where they did not monitor the airplane or calls from ATC even though both stated they heard conversation on the radio ... neither pilot noticed messages that were sent by company dispatchers ... both said they lost track of time ... (and) each pilot accessed and used his personal laptop computer while they discussed the airline crew flight scheduling procedure."
