In the scene where Lauren and Sandy are on the conveyor belt in the bowels of the Albuquerque airport, Lauren throws a suitcase at the CIA agent right before he hits his head on the light fixture. As she picks up the bag, it's a duffel bag. Quickly it changes to a suitcase. By the time it hits his head, it's morphed into yet a third piece of luggage.
Lauren and Sandy report Michael is alive to a police officer who is wearing a lieutenant's bar on each collar but a New York City police captain's badge - which has three points on the top edge. A lieutenant's badge is a round sunburst.
When they are at the airport in NYC and the ticket agent pulls up potential flights for the two ladies to take, she reads flight 225 going through Kansas City, but if you look at the computer screen it reads Eastern Airlines Flight 225 going through Atlanta not Kansas City.
When Lauren and Sandy are being chased by the CIA while attempting to get on the plane in New York, Sandy throws money "thwarting" the CIA agents. If the CIA agents wanted to actually capture them, they could have easily had the plane held at the gate where they could have boarded the plane and taken them into custody.
At one point, both Lauren and Sandy hide in automatic dryers that are on. First, most automatic dryers wouldn't function with the weight of a human in it. Second, if both of them are in dryers at the same time, who turned them on?
At the beginning of the film, when Lauren is leaving her acting class, she stops at a Coke machine. Though she clearly presses a space above where the button is with the side of her hand to select a beverage, she then leans down and retrieves a Coke.
