We sincerely apologize to our customers for their experience on Flight 1203 on September 15. The flight crew followed procedures to return to SLC where our teams on the ground supported our customers with their immediate needs. Medical personnel met the flight at the gate and identified 10 individuals as needing evaluation or treatment. Delta offered to cover transportation for these customers to medical facilities. Delta technicians worked the pressurization issue on the aircraft successfully. It was taken out of service on the morning of Sept. 15 and went back into service on September 16.
It is unclear precisely why the cabin pressurization issue happened and the Federal Aviation Administration is investigating the incident. Sudden depressurization is a far more common, albeit still rare, occurrence compared to the cabin not pressurizing at all. As in this incident, pilots will get the plane down to a safe altitude as quickly as possible. Not many things are complementary with airlines these days; the rideshare to the hospital, thankfully, was in this case.
