The first airport at Las Vegas was Anderson Field, opened in November 1920 southeast of present-day Sahara Ave and Paradise Rd. Purchased by the Rockwell brothers in 1925, the airfield was renamed Rockwell Field, and in April 1926 Western Air Express (WAE) began carrying mail (and eventually passengers). When the brothers sold Rockwell Field and the new owner canceled WAE's lease, the airline had to look for another airport. Local businessman P. A. Simon had built an airfield northeast of the city (now Nellis Air Force Base) and WAE moved there in November 1929 and bought the field a few years later.
