In the beginning of the movie, while in the simulator, a "rapid decompression" scenario is thrown at the crew. But with clearance to land AND the runway in sight, there's no way they'd be at 8,000 feet (the maximum normal airliner cabin pressure), let alone the 10,000 feet James Cromwell mentions outside the simulator. And as the plane descends toward the airport, the pressure reduces gently anyway to match the ambient air pressure of the destination.
