Delta plane plunges 27,000 feet in 10 minutes as oxygen masks suddenly drop aboard flight
The Federal Aviation Administration is reviewing two separate Delta Air Lines flights following cabin pressurization problems. One incident involved flight DL2311, a Boeing 737 traveling from Los Angeles to Salt Lake City, which plunged from 36,200 feet to 9,000 feet in 10 minutes before diverting to Las Vegas. A second flight from New York to Phoenix also returned to JFK International Airport after the crew reported a pressurization issue. Both events triggered the deployment of passenger oxygen masks during rapid descents.

FAA investigates Delta after two flights suffer pressurization failures
The Federal Aviation Administration is reviewing two separate Delta Air Lines flights following cabin pressurization problems. One incident involved flight DL2311, a Boeing 737 traveling from Los Angeles to Salt Lake City, which plunged from 36,200 feet to 9,000 feet in 10 minutes before diverting to Las Vegas. A second flight from New York to Phoenix also returned to JFK International Airport after the crew reported a pressurization issue. Both events triggered the deployment of passenger oxygen masks during rapid descents.
Why it matters
Rapid decompression requires pilots to descend quickly to a breathable altitude to prevent passenger hypoxia. Multiple pressurization events within a short window often prompt regulatory scrutiny to determine if a systemic maintenance or mechanical flaw exists across a fleet.
What is confirmed
- Delta flight DL2311 descended from approximately 36,200 feet to 9,000 feet in about 10 minutes.
- The Federal Aviation Administration is reviewing two separate Delta flights after pressurization problems prompted emergency responses.
- Flight DL2311 diverted to Harry Reid International Airport in Las Vegas.
- A Delta flight from JFK International Airport to Phoenix returned to New York after a reported cabin pressurization issue.
What to watch next
- FAA findings on the cause of the pressure losses
- Statements from Delta Air Lines regarding fleet-wide inspections
- Confirmation of any mechanical commonalities between the Boeing 737 and other affected aircraft

Delta Boeing 737 Diverts to Las Vegas After 27,000-Foot Descent
A Delta Air Lines flight from Los Angeles to Salt Lake City diverted to Las Vegas after the aircraft plunged 27,000 feet in 10 minutes. The rapid descent followed a cabin pressure emergency that triggered the deployment of oxygen masks for passengers. The Boeing 737 descended to 9,000 feet during the incident. The pilot described the event as a cabin pressure emergency requiring a rapid response.
Why it matters
Rapid decompression requires pilots to descend quickly to an altitude where passengers can breathe without supplemental oxygen. This incident involves a Boeing 737, a widely used narrow-body aircraft. The flight was forced to change its destination to Las Vegas to address the emergency.
What is confirmed
- A Delta Air Lines flight plunged 27,000 feet in 10 minutes.
- Oxygen masks deployed mid-flight during the descent.
- The aircraft involved was a Boeing 737.
- The plane descended to 9,000 feet.
- The flight was traveling from Los Angeles to Salt Lake City and diverted to Las Vegas.
Still unconfirmed
- The descent was described by a source as "Pretty Traumatic".
What to watch next
- Official report on the cause of the cabin pressure failure
- Statement from the FAA or NTSB regarding the aircraft's maintenance history
