DENVER (AP) -- A Frontier Airlines flight heading for San Diego has landed safely in Denver, after instruments showed a possible loss in cabin pressure.
A spokesman for parent company Republic Airways says instruments notified the flight crew Monday morning of the loss in pressurization, shortly after Flight 1557 left Denver International Airport. The flight crew declared an emergency and returned to Denver.
Republic spokesman Peter Kowalchuk says oxygen masks didn't deploy. He says the flight was carrying 98 passengers and four crew members.
