NEW YORK— A Delta Air Lines (DL) Boeing 757-200 returned to John F. Kennedy International Airport (JFK) on Thursday morning after its crew reported a cabin pressurization issue during a flight to Phoenix Sky Harbor International Airport (PHX).
Flight DL791 safely landed back at JFK after the pilots declared an emergency and requested priority handling from air traffic control.
The aircraft departed JFK shortly before 8:00 a.m. local time with 155 passengers and six crew members onboard.
It was scheduled to operate a roughly five-hour service to Phoenix, but the reported pressure problem prompted the crew to turn the aircraft around and return to New York, where it landed shortly after 10:20 a.m.
DL791 Returns to New York JFK After Pressurization Issue
The crew followed established procedures after identifying the cabin pressurization issue and declared an emergency to receive priority treatment from air traffic control.
The decision allowed the aircraft to return to JFK while managing the situation in accordance with normal operational procedures.
Delta said the flight landed safely and apologized to passengers for the disruption. There were no reported injuries among the passengers or crew, while the aircraft was taken for further inspection after arriving back at the airport.
The incident caused a significant interruption to the planned New York-Phoenix service, although the available reports did not indicate any further safety problems after the aircraft landed.
Delta’s maintenance teams were assigned to evaluate the Boeing 757-200 and determine the cause of the reported pressurization issue.
Boeing 757 Fleet Supports Delta Operations
The return of DL791 also highlights the continued role of the Boeing 757-200 within Delta’s fleet. The airline has retained the aircraft for several decades because its combination of passenger capacity, performance, and range allows it to serve a wide variety of domestic and longer routes.
Delta’s 757-200 fleet remains substantial, with 75 aircraft reported in service as of June 30, 2026. Those aircraft have an average age of 28.2 years, making the 757-200 one of the older aircraft types still operating across the carrier’s mainline fleet.
However, the reported pressurization issue should not be treated as evidence that the age of DL791 caused the problem.
Aircraft technical issues can occur for different reasons, and the available information does not establish a connection between the aircraft’s age and Thursday’s event.
Delta Moves Toward Gradual Fleet Replacement
Delta has gradually reduced the number of Boeing 757-200s in its fleet while increasing deliveries of newer narrowbody aircraft.
The airline operated 100 757-200s in June 2022, compared with 75 in June 2026, while its Airbus A321neo fleet expanded significantly during the same period.
The Airbus A321neo is positioned as an important replacement for the 757-200, offering Delta additional capacity and improved operating efficiency.
Delta has also committed to Boeing 737 MAX 10 aircraft, giving the airline another option as it gradually modernizes its narrowbody fleet, Simple Flying reported.
