Turning back to SLC
The Airbus A330-900 continued climbing as it departed SLC, reaching a maximum altitude of 35,000 ft (10,668 m). However, at 17:53, the widebody jet began turning back and descending to SLC. The flight crew never squawked 7700, the code for a general emergency onboard, during the entire duration of the flight.
After landing at SLC, Delta Air Lines A330-900 has no further scheduled flights, according to Flightradar24 data. Its subsequent itinerary from AMS to New York John F. Kennedy International Airport (JFK) has also been canceled. The flight-tracking website’s records showed that the aircraft landed at SLC at 19:29. Meanwhile, Delta Air Lines sent a replacement aircraft, an Airbus A330-900, registered as N419DX, to operate the flight between SLC and AMS using the special flight number DL9906. The aircraft, which departed SLC at 15:12, landed at the Dutch capital at 7:20 (UTC +1) on March 25, 2024.
