Boeing’s 737 MAX has resumed passenger flights in the US with an American Airlines flight between Miami and New York.
Regulators grounded the plane in March 2019 following two separate deadly crashes within five months.
The Federal Aviation Administration (FAA) lifted the ban last month after Boeing agreed to new safeguards.
American Airlines’ flight on Tuesday showed its confidence in the safety of the 737 MAX.
“This is an aircraft that has been more highly scrutinised than any ever before. We’re very confident that this aircraft is the safest in the skies,” the airline’s president Robert Isom said before the flight’s departure.
American Airlines currently has 31 737 MAX aircraft, including seven which were delivered after the FAA lifted its safety ban in November.
The airline and aerospace giant Boeing have both sought to reassure the public over the plane’s safety, although polls suggest that might be difficult.
A Reuters/IPSOS poll shows that more than half of passengers are wary of taking the jet when reminded of two fatal crashes that led to the grounding.
