Pure Luck

Continuity mistake: When Martin Short climbs over the hood of the Jeep, he knocks the windshield glass completely out of the frame. A minute later, the glass is installed as normal.

Revealing mistake: When the plane is delayed because the luggage got crushed, the sign changes their flight status to DELAYED. It's obvious that the one that changed is the only row meant to move. The letters are spaced out so that they can flip over but all the other letters have no spaces and actually look like stickers.
