Factual error: The shot of the plane in the Melbourne airport before it took off, and the one in Los Angeles after it lands are of the same place.
Continuity mistake: Scott slaps Jennifer. Seconds later she sees the scorpion and lowers her hand. The angle changes and she is lowering her hand again.
Revealing mistake: After the old man is blown away, together with dozens of papers and other stuff, there's a brief shot of the door and some debris remains close to the open door, but don't move an inch.
Continuity mistake: The scorpion exits the cellar through the stairs, and a shot shows it running from the back of the plane towards the front. Then Jennifer comes up those same stairs and we can see she's in the front of the plane, by the cockpit.
Revealing mistake: After Jennifer saves Milhouse, the scorpion is seen running around the plane, and the shots are reversed and repeated.
Continuity mistake: When Scott points the gun, the sky is dark seen from inside the plane, but daylight from the aerial view.

Revealing mistake: The tentacle slaps the Captain, but he's already got the wound.

Continuity mistake: The amount of seats in Business Class keeps increasing and decreasing throughout the movie, mainly at the end.
Continuity mistake: Jennifer is fighting against the queen and ducks her blows. The angles keep changing with her moves, but each one is inconsistent with the previous position.
Continuity mistake: When Jan is killed, she keeps changing from lying down, sitting, or hanging from the side of the seat. She goes from one to another depending on the angle.
Visible crew/equipment: When the Arabs try to fix the circuits, Scott places the hat on his head and the shadow of a boom mike is seen above him.
Continuity mistake: While Milhouse points the gun at the passengers, a scorpion comes from behind a curtain. From its point of view everyone is standing up really close, but half a second afterwards, they're all sitting down except for the old man, who's managed to move five meters away.
Continuity mistake: Before a passenger is hit by a flying suitcase, he is comforting a woman. Her head keeps swapping positions depending on the angle.
Continuity mistake: After the Arabs stab the scorpion, there's a very brief shot of Jennifer pointing out with her arm, but after this shot she is in a totally different position.
Visible crew/equipment: When the crew is checking the toolbox to see how to kill the scorpions, boom mics are seen at the ceiling.
Continuity mistake: Jennifer gives a credit card to the Captain and her head's position differs between the front and side shots.
Continuity mistake: Jan's friend dies and places her blood filled hand on the window, from a different angle the hand is on the wall and the amount of wall has decreased.
