EXHIBIT INDEX

Volaris Reports May 2024 Traffic Results:

86% Load Factor

Mexico City, Mexico, June 6, 2024 – 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 2024 preliminary traffic results.

In May 2024, Volaris' ASM capacity decreased by 17.5% year-over-year due to the accelerated Pratt & Whitney engine inspections and the resulting aircraft groundings. However, load factor increased by 1.6 pp YoY to 86.1%, as RPMs decreased by less than capacity. Mexican domestic RPMs decreased by 22.0%, while international RPMs decreased by 3.6%. Volaris transported 2.4 million passengers during the month.

Enrique Beltranena, Volaris’ President, and CEO said: “Despite limitations in capacity growth due to fleet availability, we have successfully increased capacity in the U.S.-Mexico transborder market while optimizing our entire network. The international market now represents over 40% of our total capacity, leveraging our ability to generate US dollar sales. Further, our strategic adjustments to the domestic network are yielding promising results. Booking trends for the remainder of the second quarter are meeting our expectations and showing robust performance.”

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 several factors. It cannot be inferred that any period’s performance or its comparison year over year will indicate a similar performance in the future.
