My dad has a trip to St. Louis tomorrow for business, and for some reason his company is having him fly from Des Moines. I got his flight numbers to check his flights for him. He has a layover in Chicago. His flight from DM to Chicago is on time, but on Chicago O'hare's website, it says the flight to St. Louis is cancelled. However according to American Airlines site, the flight is on time. St. Louis airport also says the arriving flight from Chicago is cancelled. What do you think>
