Dallas/Fort Worth International Airport is one of the most popular airports in the world and, along with a SIXT rental car, is your key to exploring the Dallas-Fort Worth metroplex area. If you have some down time while at this airport, be sure to enjoy your time in one of the restaurants, yoga studios or lounges. For your leisure time in the area, we recommend you visit The Sixth Floor Museum and Dealy Plaza in Dallas or the Fort Worth Stockyards National Historic District.
