With the loss of all 239 aboard , Flight 370 is the second-deadliest incident involving a Boeing 777 and the second-deadliest incident of Malaysia Airlines ' history , second to Flight 17 in both categories . Malaysia Airlines was struggling financially , a problem that was exacerbated by a decrease of ticket sales after the disappearance of Flight 370 and the downing of Flight 17 ; the airline was re-nationalised by the end of 2014 . The Malaysian government received significant criticism , especially from China , for failing to disclose information promptly during the early weeks of the search . Flight 370 's disappearance brought to public attention the limits of aircraft tracking and flight recorders , including the limited battery life of Underwater Locator Beacons ( an issue that had been raised about four years earlier following the loss of Air France Flight 447 , but had never been resolved ) . In response to Flight 370 's disappearance , the International Civil Aviation Organization ( ICAO ) adopted new standards for aircraft position reporting over open ocean , extended recording time for cockpit voice recorders , and , starting from 2020 , new aircraft designs will be required to have a means of recovering the flight recorders , or the information they contain , before they sink into the water
