Long international flights are planned very carefully. Airlines plan the route, fuel, crew time, and safety steps before the plane even leaves the airport. When a long flight turns around in the middle of the ocean and goes back to where it started, it is a rare event.
This is what happened to Delta flight DL39, which was flying from Los Angeles (LAX) to Shanghai (PVG). The plane flew for many hours over the Pacific Ocean and then returned to Los Angeles. Many people called it a “flight to nowhere” because the passengers ended up back at the same airport.
This article explains what Delta DL39 is, what happened on the flight, why planes return to the airport, and what this event means for passengers and airlines.
What Is Delta DL39?
Delta DL39 is a long international flight. It connects the United States and China.

Everyone landed back at LAX

Why Did the Plane Return to LAX?
Reports said the flight returned because of a disruptive passenger. This means a passenger was causing serious trouble on the plane.
Airlines take safety very seriously. If someone is acting in a dangerous or threatening way, the pilots may decide that it is safer to land the plane as soon as possible.
Common Reasons Planes Turn Back
Planes can return to the airport for many reasons, such as:
-
A passenger becomes very sick
-
A passenger causes trouble or becomes violent
-
There is a problem with the plane
-
There is smoke or a strange smell
-
Bad weather at the destination
-
Crew members reach their work time limit
In this case, the main reported reason was passenger behavior.

Why Didn’t the Plane Land at Another Airport?
Some people ask why the plane did not land at another airport instead of going all the way back to Los Angeles. Over the Pacific Ocean, there are very few big airports that can handle a large international plane with many passengers.
Going back to LAX was safer and easier to manage.
Return to LAX vs. Landing Somewhere Else
| Factor | Return to LAX | Land at Another Airport |
|---|---|---|
| Airline staff | Full Delta staff available | Limited or no Delta staff |
| Police and security | Easy access in Los Angeles | May be harder in another country |
| Plane maintenance | Full service at LAX | Limited service |
| Passenger help | Hotels and rebooking easier | More difficult |
| Language and rules | Familiar to airline and crew | Different laws and languages |
Because of these reasons, going back to the starting airport is sometimes the best choice.
