Dallas-Fort Worth Airport is the size of Manhattan and it is true that transit passengers can find plenty of shopping and get a workout just walking between terminals. But if the layover is more than a couple of hours, consider venturing into the city. With new ridesharing services such as Uber and Lyft, getting to downtown Dallas is only $25 each way. The newly revitalized downtown is home to beautiful parks, renovated museums and top-notch restaurants. Take in an afternoon at the Dallas Museum of Art, a stroll through the Dallas Galleria or the recently opened George W. Bush Presidential Library. Enjoy a Texas steakhouse or Southwestern specialties before heading back to the airport.
