Dallas-Fort Worth is American Airlines' largest hub, and the airline has built a real transatlantic network around it. There are nonstops to London, Paris, Frankfurt, Madrid, Barcelona and Rome, and seasonal routes to other cities, with partners such as British Airways, Lufthansa and Air France adding their own flights.
For North Texans, that means you can often fly to Europe without a connection, which is worth a lot on a trip that is already long. The routes and frequencies change by season, so check what is flying for your dates, and look at connecting options too, since they are sometimes much cheaper.
