Delta 737‑900ER Rapidly Descends to 9,000 Feet Over LAX After Cabin Depressurization

Delta Air Lines flight 2311 left Los Angeles International Airport bound for Salt Lake City when, just before landing, a Boeing 737‑900ER experienced a sudden cabin depressurization. The aircraft dropped rapidly to an altitude of about 9,000 feet, prompting the automatic deployment of emergency oxygen masks for all passengers and crew. The crew followed standard depressurization procedures, descending to a safe altitude before touchdown. The incident occurred only minutes before the aircraft was due to land, and no injuries were reported. While the exact cause of the depressurization remains under investigation, the event illustrates how quickly a commercial jet can lose cabin pressure and the necessity of immediate descent and oxygen delivery protocols.
