A United Airlines Boeing 737 MAX 8 declared an emergency and returned to Las Vegas on the night of Saturday, 24 October, after a flight attendant spotted a passenger apparently texting that he intended to hijack the aircraft. Law enforcement met the plane on arrival.
According to Simple Flying, flight UA1681 had departed Las Vegas Harry Reid International Airport (LAS) at 10:51 PM local time, bound for Newark Liberty International Airport (EWR). The service was running eleven minutes late against its scheduled 10:40 PM departure.
What Happened on United Airlines Flight UA1681
The aircraft had climbed to 24,000 feet when the flight attendant spotted the suspicious text message and alerted the captain. The cockpit was locked down, and the captain made the decision to return to Las Vegas.
Crucially, Simple Flying reports that the passenger was not made aware that the crew had seen the message. ATC audio shared on social media captured a crew member relaying the situation: “The passenger doesn’t know anything is going on. The flight attendant saw him texting that he was going to hijack the aircraft.”
The aircraft made a U-turn over the Arizona ghost town of Oak Grove before routing back towards Las Vegas.
Squawk 7700 and the Emergency Declaration
Once the crew had assessed the situation, the aircraft squawked 7700, declaring a general emergency. This gave the flight priority handling for its return to Las Vegas. You can find details of this and other active emergencies in our Squawk 7700 hub, which tracks live emergencies and maintains an incident archive.
Because the flight had been loaded with fuel for a nearly six-hour journey to Newark, the aircraft was above its normal landing weight when it turned back. Simple Flying notes that the captain reported approximately 24,800 pounds (11,249 kg) of fuel remaining.
An Overweight Landing Back at Las Vegas
The Boeing 737 MAX 8 cannot dump fuel, so the crew flew at a reduced speed to burn off as much as possible before touching down. The captain warned air traffic control that the full length of Runway 26L might be needed.
The aircraft landed safely on Runway 26L at 11:42 PM local time, around 50 minutes after its initial departure, according to flight tracker data cited by Simple Flying. Law enforcement met the plane and spoke with the passenger, who reportedly remained unaware of the crew’s concern throughout the flight.
The Aircraft Involved
The aircraft at the centre of the incident was N17310, a Boeing 737 MAX 8 delivered to United Airlines in 2023. It is configured in a two-class layout accommodating up to 166 passengers. You can look up the full history and details of this airframe using our Aircraft Search tool.
United Airlines has been expanding its operations in recent months. Earlier this week, we reported on the airline opening two new flight attendant bases in Dallas and Sacramento.
What Happened to the Flight Afterwards
After law enforcement had dealt with the situation, the flight crew timed out, meaning a replacement service was required. Simple Flying reports that a replacement departure left Las Vegas at 7:03 AM on Sunday, 25 October, arriving in Newark more than eight hours late.
Simple Flying noted that a United Airlines spokesperson could not immediately be reached for comment at the time of publication.
The Bottom Line
A swift and composed response by the United Airlines cabin crew prevented what could have been a far more disruptive situation. The flight attendant spotted the message, alerted the captain without alarming the passenger, and the crew executed a textbook emergency return. The passenger was handed to law enforcement without incident.
