Boeing 787-9 of United Airlines Emergency Landing at Sydney Airport. The Sydney airport was closed and the nearby roads were closed after a United Airlines flight on Monday morning.

The security officer, Airservices Australia, told that Mayday's call was automatically activated because the fuel gauge on the aircraft had dropped below a certain level and was not "unusual."

"It does not mean that he does not have more fuel and that he has to land immediately," the spokeswoman said.

"You still have a lot of fuel left."

The main roads around the airport closed at 6:30 am but were reopened shortly after.

News Corp reports that the road closures should allow the passage of emergency vehicles, which were waiting just in case.

But in the air, the 239 people aboard the flight did not know something was wrong.

A spokeswoman for the Sydney airport said previous reports of carbon dioxide leaks were false and that she simply reported on the presence of dry ice on board.

"Every plane says there's something dangerous on the plane and it's an airplane that has dry ice," he said.

The plane landed safely and the roads were reopened at 6:39 am
