Plot hole: When Miss Scarlet tells the other guests, they can pay her in government information, she forgets Mrs White is the only to have no connection to the government and thus can't pay her that way, nor does she have any more money like the others.
Plot hole: In the airport scene when Chance runs through security after Cody, he is chased by an airport police officer. During later shots you can see the officer in hot pursuit not far behind Chance. Yet when he gets to the exit gate beside the washroom where Cody was hiding, Chance spends several seconds scanning the gate area before setting off to the washroom. Surely the airport officer would've long caught up to Chance by then, but instead the same officer does not re-appear until some time later after Chance has intercepted Cody in the washroom.
