Chuck

When the plane lands, there is an announcement, "Welcome to Paris Charles de Gaulle. Bienvenue à Paris Charles de Gaulle." Of course, in real life, the pilot would state things like time and temperature, which would be too long for a TV episode. But Charles de Gaulle Airport is not, in fact, in Paris. It's in nearby Roissy. Non-Parisians refer to it as Charles de Gaulle, Parisians tend to just call it Roissy. It is usually referred to on planes as "aéroport de Paris Roissy Charles de Gaulle" or "Paris airport Roissy Charles de Gaulle," or something similar. But it's always called Roissy, because that's where it is.

When Chuck finds the coffin, the hand that touches the label has a ring on it, although Chuck never wears one in the other scenes.

When Chuck is asked by Hannah (Kristin Kreuk) to analyze the other people sitting with them in first class, the first two people are classified as "Syrian dignitaries". This is obviously false since the man on the left is wearing a turban, meaning that he is a Sikh, who only come from India.

When Chuck is told to stay on the plane, a large sized Eiffel Tower can be seen out the window, which is impossible. Planes do not have the right to fly over Paris, and the airport is too far away from Paris to see the Eiffel Tower as big as it appeared in that scene.
