Delta Air Lines Flight 389 took off from Detroit around 10:30 a.m. local time on Saturday and was scheduled to land in Shanghai within 16 hours. However, flight-tracking data shows that nearly five hours into the journey, the Airbus A350 changed course just off the Alaskan coast near Juneau. It rerouted to Los Angeles, around 2,000 miles off course as the crow flies, touching down three and a half hours later.
After a United Airlines flight U-turned and landed back in Newark, passengers reached London 11 hours later than expected, and after their original plane. Thursday's Flight 934 took off from Newark Liberty International Airport shortly after 9 a.m. However, data from Flightradar24 shows that just around 20 minutes later, the Boeing 767 turned around short of Boston. It then circled half a dozen times over upstate New York before landing back at Newark, 1 hour and 45 minutes after departing from there.
