Emergency Landing: Southwest Flight Diverted to Charleston Due to Suspected Fuel Leak

A dramatic turn of events unfolded on July 20, 2026, when a Southwest Airlines flight was forced to make an emergency landing at Charleston International Airport. The Boeing 737-800 aircraft, operating as WN4761, was en route from Orlando to Manchester, New Hampshire, when the crew detected a suspected fuel leak at an altitude of 37,000 feet. The plane, which took off from Orlando International Airport at 8:54 a.m. EDT, was diverted to Charleston after the crew declared an airborne emergency and alerted air traffic controllers with a 'squawk 7700' transponder code. Despite the alarming situation, the pilot managed to land the plane safely on Runway 15, with emergency response vehicles waiting in anticipation. The incident, which occurred about an hour into the flight, prompted a thorough investigation to determine the cause of the suspected fuel leak. Fortunately, none of the 137 passengers and crew members on board were injured. The airline has launched a 360-degree maintenance inspection to ensure the safety of its aircraft.
