Gail Kornberg's gold hoop earrings disappear and reappear throughout the movie.
The blood stains on the man with a piece of plastic stuck on his face change between two continuous shots.
On the visual approach to Hilo, they are cleared to land on runway 8. The plane lands on runway 2.
When Mimi starts calling Maui Tower after attempting to restart the #1 engine, the clouds in the background change between shots.
After the pilots have lowered the landing gear there are several external shots of the aircraft with gear up (though they have no reason to doubt that the rear gear is down at this point).
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.
