EXHIBIT INDEX

Volaris Reports June 2023 Traffic Results:

15% YoY Demand Growth with an 83% Load Factor

Mexico City, Mexico, July 7, 2023 – Controladora Vuela Compañía de Aviación, S.A.B. de C.V. (NYSE: VLRS and BMV: VOLAR) (“Volaris” or “the Company”), the ultra-low-cost carrier (ULCC) serving Mexico, the United States, Central, and South America, reports its June 2023 preliminary traffic results.

In June 2023, Volaris’ capacity (measured in ASMs) increased by 16.1% year-over-year, while demand (measured in RPMs) increased by 14.6%; the result was a load factor decrease of 1.1 pp YoY to 83.3%. Volaris transported 2.7 million passengers during the month, an 13.7% increase compared to June 2022. Demand in the Mexican domestic and international markets increased by 10.4% and 24.1%, respectively.

Enrique Beltranena, Volaris' President and CEO, remarked: "Demand remained strong in the international markets, including US transborder and Central America. We continue to anticipate that Mexico will return to Category 1 with the US and the team has started planning network changes that will allow us to allocate growth to the strong international markets.”

Beltranena went on to say: “We have also started preparation for peak summer travel. To enhance operational performance, Volaris has recently extended several leases that will provide additional capacity to our network and allow us to more quickly support any operational challenges we may face in this busy time."
