Something to note about the McCallister's flight to Paris in Home Alone is that the stock footage shows a McDonnell Douglas DC-10-10, which would not be used on such a flight, as it doesn't have the range for a transatlantic flight from Chicago to Paris. In real life, a DC-10-30 would be the more likely choice for an American Airlines flight between Chicago and Paris in 1990. The DC-10-30 can be distinguished from the DC-10-10 by it's different landing gear configuration. I guess the editors couldn't find any stock footage of an American Airlines DC-10-30 and so had to make do. It's worth noting that in the script, the McCallister's flight was said to be an Air France 747.
Home Alone 2: Lost in New York also makes extensive use of American Airlines. In this case, both Kevin's flight to New York and the rest of his family's flight to Miami use Boeing 767s. The former is accurate, as AA use 767s on Chicago to New York flights, but the Miami flight should in fact be an Airbus A300, as they were the only widebodies used by American Airlines on Chicago to Miami flights at that time. Incidentally, the film takes a bit of liberty with the timing. Both Kevin and his family are seen to have arrived at their separate destinations at roughly the same time, whereas in real life, a flight from Chicago to New York takes around two hours, while Chicago to Miami takes about three hours, so the scene of the family discovering that Kevin isn't with them should have taken place much later than Kevin discovering that he's ended up in New York instead of Miami. Still, they're movies and we have to suspend our disbelief.
