Delta Air Lines DAL276 Airbus A330 Returns to Boston Logan After Reaching 10,366 Feet

Delta Air Lines flight DAL276, an Airbus A330-300 registered N820NW, departed Boston Logan International Airport (KBOS) on June 26, 2026 at 00:00 UTC on a route bound for France. The aircraft never climbed beyond 10,366 feet, well short of any transatlantic cruise altitude, and returned to KBOS approximately 50 minutes after the tracked flight began.

SkyMeter's analysis of ADS-B tracking data shows the aircraft began its takeoff roll around 00:14 UTC, lifting off on a heading of 66 degrees to the northeast and climbing at rates reaching 3,660 feet per minute. The flight then executed a series of left turns, swinging north and then west near Beverly Regional Airport (KBVY), and finally south near Laurence G. Hanscom Field (KBED), tracing a broad arc back toward Boston. The aircraft leveled briefly at 10,366 feet around 00:21 UTC before beginning its descent, with the steepest recorded descent rate reaching 3,420 feet per minute. A stabilized approach followed on a heading of roughly 133 degrees, with a steady descent from about 2,100 feet, and the aircraft touched down at approximately 00:35 UTC, about 21 minutes after becoming airborne.

The reason for the return was not discernible from the ADS-B data. The full replay of DAL276, including the departure, the turn-back arc over the Boston area, and the return landing, is available on SkyMeter.
