Factual error: The Royal Canadian Mounted Police are shown checking baggage in the final scenes at the same time that FBI agents are making arrests. The flight landed in Goose Bay, Newfoundland and Labrador, Canada. According to the Criminal Code of Canada, any crime committed during an international flight that ends on Canadian soil is deemed to have been committed in Canada. That being the case, the RCMP as the national police force has full jurisdiction. There is no way the FBI would be involved at that point.

Plot hole: Bomb squad vehicles are present at the airport when the plane lands. There is no bomb disposal unit in Goose. If one is needed it has to come from two provinces away - travel time by vehicle, in March, going flat out: minimum 20 hours + a 2.5 hr ferry trip. Not to mention that the markings on said vehicles are American: transportation of those vehicles from the US wouldn't have been any easier than from Canada, on the contrary, so again, they wouldn't have had the time to bring them over.

Other: When either Kyle or Carson run down the staircase the rails move significantly. On a real plane this would not have passed the pre-flight safety checks and the plane would have been grounded. Nothing in the film suggests the rails would have loosened.

Factual error: At the end of the movie, when they land in Goose Bay, Newfoundland and Labrador, the firetrucks that rush to the scene are the wrong color. The firefighters at the Goose Bay airport drive yellow fire trucks, not red ones.

Continuity: The outline of the heart the little girl drew on the window change from when she drew it to when Jodi Foster breathes on it. This has nothing to do with the inside/outside shot of the heart.

Continuity: In the shot when Carson put the bomb in Avionics to activate it, he puts down two parts. The part to the right (from Julia's perspective) is a little inclined. But when Kyle is in Avionics looking for Julia, that part of the bomb is not inclined.

Factual error: At the end of the movie when Kyle and her daughter are being driven away we see a shot of the licence plate. Although it is marked "Newfoundland and Labrador" the numbers are before the letters, the reverse of what it is in the province.

Continuity: Near the end when the Air Marshall is getting off the plane to "get the two agents" there is a shot of him from behind walking off the plane with snow covering most of the ground, but when the shot cuts to a wide shot from the side of him all the snow is gone.

Factual error: Carson's face would have been a whole lot more disfigured had he actually been hit that hard with a fire extinguisher.

Continuity: When Stephanie is about to check avionics, Fiona holds the flashlight by the lamp end (bulb) as Stephanie takes the flashlight. However, in the next shot, Fiona still holds the flashlight, but she now holds the other end as Stephanie takes the flashlight from her.

Revealing: When Kyle is running up to the cockpit to pound on the door for the captain, you can hear an extra shout out "Hey, Jodie Foster."

Continuity: When Jodie Foster is banging on the captain's door, the "air marshal" grabs her from the back. When he does that, she is pressed against the door, with the peephole by her mouth. When he says, "Can I let you go," she says "Yes." The next shot, the peephole has moved by at least a few inches.
