Mexico City, Mexico August 4, 2015 – Volaris* (NYSE: VLRS and BMV: VOLAR), the ultra-low-cost airline serving Mexico, the United States and Central America, reports July 2015 and year-to-date preliminary traffic results.

During the month of July 2015, Volaris increased total capacity, as measured in Available Seat Miles (ASMs), by 17.4% year over year, primarily by way of fleet up gauging and through high aircraft utilization.  Volaris transported a record 1.3 million passengers in the month, an increase of 20.6% year over year. Volaris’ total demand for July measured in Revenue Passenger Miles (RPMs) increased 17.3% year over year, reaching 1.2 billion.

Responding to strong passenger demand, Volaris increased international ASMs by 44.7%, while maintaining capacity discipline to more opportunistically increase ASMs in the domestic market by only 7.8%. Year-over-year network load factors remained flat at 87.4%.

During July 2015, Volaris started to operate one seasonal domestic route (Acapulco – Toluca) and two year-round international routes (Cancun – San Juan, Puerto Rico and Guadalajara – New York (JFK)).
