Corrected entry: After Lisa kicks Jackson, her shoe gets stuck in his leg. In the next scene (in the bathroom), she is barefoot and has had no time in between these shots to take the other shoe off her left foot.
Corrected entry: For all the trouble the assassins went through, with 8 weeks detailed surveillance on Lisa, an expensive and incredibly difficult to obtain Javelin missile and such, they picked a surprisingly poor method of attack. It's pretty clear from the technical data of the Javelin missile and the images in the movie (where the effect is exaggerated) that the attack would have a very low probability of actually killing anyone, let alone the entire family as stated. Moreover, the boat the missile was fired from was too large to hide and too small to escape sufficiently far, and the assassins would most likely be caught. As such, the operation was needlessly complicated on many points, yet it worked almost perfectly. Whomever was planning the operation had to be both a genius and an idiot at the same time, which makes it a plot hole.
Corrected entry: When Lisa wakes up after being hit in the head by Jackson, he says that he got her some aspirin, but you can't get aspirin on flights.
Corrected entry: When Lisa and Jackson are talking on the plane she looks out the window and kind of leans her head toward the head rest. The camera switches positions and when it goes back she is now looking straight ahead. A little while later it shows her do the same thing only this time her head doesn't switch between shots.
Corrected entry: Near the end where Lisa is going to save her Dad and kills the hitman with the car. When Lisa goes to see if he is dead, there is a very large pool of blood around his head. But about five minutes later when Jack goes to get the knife attached to his belt, there is only a small pool of blood.
Corrected entry: When Lisa first sits down on the plane while Jackson is putting the other passenger's luggage up in the luggage compartment, Lisa's window is full of water drops because of the weather. However, when Jackson sits back down next to Lisa, the window is completely dry.
Corrected entry: In the scene on the plane during the lightning storm, the lightning is flashing brightly directly outside the planes windows. They are at cruising altitude at this point, and although thundercloud tops may be nearly this high, the lightning comes out of the bottom of the clouds, and wouldn't be flashing through the windows into the plane cabin.
Corrected entry: When Jackson comes in the bathroom where Lisa is, we get a quick glance of the mirror which says "18-F HAS BOMB" the letters are messy and the soap is dripping down. However, in another shot of the mirror, the letters are much neater and the soap is not dripping down at all.
Corrected entry: Lisa refuses an offer from her father to pick her up at the airport because "it is going to be too late." She then explains that she'll be on the Red Eye. Red Eyes are overnight flights that arrive in the morning, and therefore wouldn't be "too late."
Corrected entry: When Lisa's father's desk is first shown, we see an old picture of Lisa playing field hockey, she's in the picture with another player with a number "2" on her shirt. However, later on when the same picture is shown, Lisa is in it by herself without an opponent.
Corrected entry: In the scene where Jackson head butts Lisa, he says "I didn't want this to get complicated Rachel". He uses the actresses' name, not the character's.
Corrected entry: The coffee spill on Lisa is different when she goes to clean up in the airport bathroom. It is perfect and round not like the splattered spill seen before.
Corrected entry: When Lisa sits down next to Jackson on the plane the camera is on top of the phone. Later when Lisa steals his phone the camera is further down the phone.
Corrected entry: The Fresh Air jet shown throughout most of the film has two engines mounted under the wings and a single engine on the tail. But shortly after the confrontation between Lisa and Jack in the plane's lavatory, there is an outside shot of the jet flying through the sky with all three engines on the tail and none under the wings.
Corrected entry: When Lisa and Cynthia are first on the phone, Cynthia turns away from the customers and we see the computer behind her. In between shots, a small window on the computer appears and disappears. This happens several times before she's actually supposed to open the smaller window to type in Lisa's code.
Corrected entry: When Lisa and Jackson are in the TexMex having a drink, you see that both of them are drinking out of straws. However when Lisa starts chugging down the drink, the straw has disappeared.
