A Delta Air Lines Airbus A330 flight from New York JFK to Tel Aviv was forced to make an emergency diversion to Dublin Airport after approximately four hours into the flight. The crew declared a squawk 7700, signaling a general emergency, due to a medical issue onboard involving one of the 174 passengers. The aircraft, still carrying a full fuel load for the long-haul journey, conducted a heavyweight landing at Dublin around 1:17 a.m. local time. Medical personnel met the flight upon arrival and transported the patient to hospital. The flight resumed its journey after departing Dublin at 5:03 a.m., with passengers expected to arrive in Tel Aviv around noon local time, about three hours later than scheduled. The incident highlights the use of squawk 7700 for emergencies, which can involve medical issues or mechanical problems, prompting ground support and emergency services. The aircraft's early position in its route and the fuel load resulted in a heavier-than-usual landing, but the operation was successful and safe.
