When driving Kris and Kelly home after a day of stewardess training, the license plates on Angela's car are California 861 BMG - plates normally seen on the Townsend Agency's white Mustang Cobra II that Kris drives.
In Angela's kitchen, she drops a square metal coffee can and measuring spoons. Yet, in the shot of the floor, there are no visible spilled coffee grounds or measuring spoons.
As the Global Airways flight is touching down on the runway, there is a "head-on" shot of a Boeing 707. It is not the Global Airways plane; it appears to have blue paint here and there, not red. Also, around the cockpit windows, the paint is different. And, it does not have any cockpit "skylights." However, in the ensuing clip (overhead) of a plane touching down, we see the Global Airways plane once more.
In the parking garage when someone tries to hit Kris with their car, the stunt double wears different shoes than Kris - wedges instead of heels.
At night, when someone in a phone booth calls Angela at her apartment, it certainly appears that the person in the phone booth is already talking, well before Angela answers the phone. BTW, the person in the phone booth appears to be a female. Regardless, the caller sure was "fidgety."
As the Global Airways plane heads back to Los Angeles, at one point, the film is flipped horizontally: on the starboard side of the plane, "Global Airways" appears backwards. Presumably the editor wanted the plane to continue flying left to right on the screen but didn't have the needed footage.
After Mai-Ling kicks in the cockpit door, there is no visible damage to either the door or frame.
From the shot outside of the cockpit, the door appears to be ever-so-slightly open just before Mai-Ling kicks it in. Additionally, from the camera inside the cockpit, the viewer is given an all-too-clear view up her skirt as the door is kicked in.
When Angela first listens to the recorded instructions, it is clear that, although she presses "play" and a voice is heard, there is no cassette in the tape player.
