EXHIBIT INDEX

Volaris Reports May 2023 Traffic Results:

17% YoY Demand Growth with an 85% Load Factor

Mexico City, Mexico, June 6, 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 May 2023 preliminary traffic results.

In May 2023, Volaris’ capacity (measured in ASMs) increased by 21.6% year-over-year, while demand (measured in RPMs) increased by 17.1%; the result was a load factor decrease of 3.2 pp YoY to 84.5%. Volaris transported 2.8 million passengers during the month, an 11.1% increase compared to May 2022. Demand in the Mexican domestic and international markets increased by 7.1% and 44.8%, respectively. To mitigate aircraft delivery delays and unexpected engine shop visits, Volaris has been able to extend six aircraft leases and add three spare aircraft to its fleet. With these additional assets, Volaris has been able to maintain its capacity growth.

Enrique Beltranena, Volaris' President and CEO, remarked: “We are proud to have recently launched 40 new routes, successfully connecting underserved cities with leisure and bus-switching routes, further solidifying Volaris' leading position in the domestic market; notably, 33 of these new routes have no air competition.”

The information included in this report has not been audited and does not provide information on the company’s future performance. Volaris’ future performance depends on many factors. It cannot be inferred that any period’s performance or its comparison year over year will indicate a similar performance in the future.
